If the required treatments are not practicable, refer to the column 'Repair Alternative'. Use the<br />
abbreviation 'CAA' for Chromic Acid Anodizing and 'SAA' for Sulfuric Acid Anodizing.<br />
Anodic coating is considered to be the superior protection.<br />
The application of wash primer is preferred in those areas that would be difficult to clean after the<br />
application of chemical conversion coating. This would prevent a chemical product being trapped between<br />
parts and subsequently causing corrosion.<br />

<strong>51</strong>-23-<strong>11</strong> .<br />
1 Cadmium plating is a procedure in which the surface of the material is given a layer of<br />
cadmium. If corrosion occurs it will remove the thin layer first. This is referred to as sacrificial<br />
corrosion.<br />
2 There are two different procedures used to put the cadmium onto the surface of the material.<br />
The first method describes a cadmium plating procedure, in which the metal parts are put<br />
into several immersion baths. The second method describes the 'DALIC' Process, which is<br />
suitable for field repairs.<br />
3 Before you start the cadmium plating procedure, make sure that the parts are clean, show a<br />
bright metal surface and are free from corrosion (Refer to Chapter <strong>51</strong>-74-00 ).<br />
4 It is recommended that cadmium plating is carried out by trained and approved personnel.<br />

3 How to Obtain the Correct Thickness<br />
The thickness of the deposited metal is controlled by the ampere-hour meter. It further<br />
depends upon the area to be plated and the specific plating factor. The specific plating factor<br />
gives the number of ampere hours required to produce a deposit in mm or inches onto a<br />
surface area of square centimeters or square inches.<br />

- Example: You have to plate an area of 25 cm² (3.875 in²) with cadmium alkaline solution.<br />
The required thickness is 0.015 mm. The correct ampere-hours setting is: 0.488 x 0.015 x<br />
25 = 0.183 ampere-hours<br />
- Example: You have to plate the same area with the same thickness, but you measure in<br />
inches. The thickness is 0.0006 in and the area has the size of 3.87 sq.in Determine the<br />
correct number of ampere-hours as follows: 80 x 0.0006 x 3.87 = 0.183 ampere-hours<br />
4 Inspection<br />
The cadmium deposit must be fine grain, smooth, and free from blisters, pitting, burns and<br />
other defects. Ensure that the cadmium deposit has good adherence to the metal surface.<br />
Check this with an adhesive tape. Put a strip of adhesive tape onto the treated surface and<br />
draw it quickly away. The adhesive tape must be free from cadmium particles.<br />
5 Procedure for non stainless steel<br />
a<br />
b<br />
Remove all grease from the repair area with a clean cloth soaked in trichloroethane<br />
(Material No. <strong>11</strong>-026 ).<br />
When the cleaning agent has evaporated, mask off all areas which are not to be treated.<br />
WARNING: CLEANING AND DEOXIDIZING SOLUTION IS HARMFUL.<br />
c<br />
d<br />
With a prepared tampon apply the cleaning and deoxidizing solution (Item 1 in the<br />

3 How to obtain the correct thickness<br />
The thickness of the deposited metal is controlled by the ampere-hour meter. It further<br />
depends upon the area to be plated and the specific plating factor. The specific plating factor<br />
gives the number of ampere hours required to produce a deposit in mm or inches onto a<br />
surface area of square centimeters or square inches.<br />

You have to plate the same area with the same thickness but you measure in inches. The<br />
thickness is 0.0006 in and the area has the size of 3.87 sq.inch. Determine the correct<br />
number of ampere hours as follows: 70 X 0.0006 X 3.87 = 0.162 ampere-hours.<br />
4 Inspection<br />
The cadmium deposit must be fine grain, smooth and free from blisters, pitting, burns and<br />
other defects. Ensure that the cadmium deposit has good adherence to the metal surface.<br />
Check this with an adhesive tape. Put a strip of adhesive tape onto the treated surface and<br />
draw it quickly away. The adhesive tape must be free from cadmium particles. For more<br />
information refer to PMS Chapter 01-02-<strong>21</strong> .<br />
5 Procedure<br />
a<br />
b<br />
c<br />
d<br />
Remove all grease from the repair area (minimum one inch outside the repair area) with<br />
a clean cloth soaked in cleaning agent (Material No. <strong>11</strong>-003 or <strong>11</strong>-026 ) and wipe dry<br />
with a clean cloth or absorbent paper.<br />
Mask as necessary to define the area to be plated. If the area was already plated with<br />
cadmium, the brush plating must overlap the existing cadmium by about 4 mm (0.157<br />
in), refer to Figure 001 .<br />
Brush Plating Procedure<br />
Use one of the alternative procedures given in Paragraph 2.B.(1).(e).5.d and 2.B.(1).<br />
(e).5.e .<br />
Using SIFCO solutions<br />
NOTE: Prepare the work place with all the items. Start the power pack, adjust the<br />
voltage to 20 V and the current to the maximum and ensure the power pack is<br />
set in 'forward' polarity. Set the bonnet on the plating tool. Wet it first with demineralised<br />
water, squeeze with hand and paper, then place the electrode in the<br />
cadmium solution.<br />
- Manually abrade the area to be plated using a water wetted abrasive paper (<strong>320</strong><br />
grade or finer) or fine SCOTCH-BRITE pad and water. Feather the edge as shown on<br />
Figure 001 .<br />
- Rinse with demineralized water. Wipe with a clean wet cloth and wipe dry with a clean<br />
cloth.<br />
- Before switching on the current, wipe the area to be treated with a pad dampened<br />
with the plating solution (Item 12) or soak a tampon with the plating solution and start<br />
the appropriate tampon movement over the plating area. Ensure you have a liquid<br />
break free condition otherwise repeat 2.B.(1).(e).5.d Paragraph 2.<br />
- Using a prepared tampon move the tampon and apply plating solution at forward<br />
current cathodic plating polarity (part connected to (-) terminal and electrode (+) see<br />
manufacturer's instructions), plate at 15 to 20 V until a visible layer of cadmium is<br />
deposited, then reduce voltage to 8 to 14 V. Move the tampon in contact and over the<br />
surface and until you get the required thickness (see the required ampere hours in<br />
Paragraph 2.B.(1).(e).4 at a speed of approximately 6 to 24 m/min or 20 to 80 feet per<br />
minute. During plating do not allow the surface to dry and move the tampon to avoid<br />
the deposit to darken (burning).<br />
NOTE: For unspecified thickness the deposit must average between 0.015 mm (0.0006<br />
in) and a minimum of 0.01 mm (0.0004 in), refer to Paragraph 2.B.(1).(e).4 .<br />
- Rinse the area with clean cold running water.<br />
- Apply passivating solution (Item 13) with a brush or swab to the plated surface.<br />
Allow the solution to remain in contact for 15 to 30 seconds until a yellow or gold<br />
appearance is obtained.<br />

Example 1:<br />
You have to plate an area of 25 cm² (3.875 in²) with SPS 5070 cadmium LHE plating<br />
solution. The required thickness is 0.015 mm, the correct ampere hours setting is: 0.4 x<br />
0.015 x 25 = 0.15 ampere-hours.<br />
Example 2:<br />
You have to plate the same area with the same thickness, but you measure in inches. The<br />
thickness is 0.0006 in and the area has the size of 3.87 sq.inch. Determine the correct<br />
number of ampere hours as follows: 70 x 0.0006 x 3.87 = 0.162 ampere-hours.<br />
4 Inspection<br />
The cadmium deposit must be fine grain, smooth and free from blisters, pitting, burns and<br />
other defects. Ensure that the cadmium deposit has good adherence to the metal surface.<br />
Check this with an adhesive tape. Put a strip of adhesive tape onto the treated surface and<br />
draw it quickly away. The adhesive tape must be free from cadmium particles. Refer to PMS<br />
Chapter 01-02-<strong>21</strong> for more information.<br />
5 Procedure<br />

c<br />
Remove all grease from the repair area (minimum one inch outside the repair area) with<br />
a clean cloth soaked in cleaning agent (Material No. <strong>11</strong>-003 or <strong>11</strong>-026 ) and wipe dry<br />
with a clean cloth or absorbent paper.<br />
Mask as necessary to define the area to be plated. If the area was already plated with<br />
cadmium, the brush plating must overlap the existing cadmium by about 4 mm (0.157<br />
in), refer to Figure 001 .<br />

depends upon the area to be plated and the specific plating factor. The specific plating factor<br />
gives the number of ampere-hours required to produce a deposit in mm or inches onto a<br />
surface area of square centimeters or square inches.<br />

Table 007 - Specific Plating Factor<br />
Example 1:<br />
You have to plate an area of 25 cm² (3.875 in²) with SPS 5070 cadmium LHE plating<br />
solution. The required thickness is 0.015 mm, the correct ampere hours setting is: 0.4 x<br />
0.015 x 25 = 0.15 ampere-hours.<br />
Example 2:<br />
You have to plate the same area with the same thickness, but you measure in inches. The<br />
thickness is 0.0006 in and the area has the size of 3.87 sq.inch. Determine the correct<br />
number of ampere hours as follows: 70 x 0.0006 x 3.87 = 0.162 ampere-hours.<br />
4 Inspection<br />
The cadmium deposit must be fine grain, smooth and free from blisters, pitting, burns and<br />
other defects. Ensure that the cadmium deposit has good adherence to the metal surface.<br />
Check this with an adhesive tape. Put a strip of adhesive tape onto the treated surface and<br />
draw it quickly away. The adhesive tape must be free from cadmium particles. Refer to PMS<br />
Chapter 01-02-<strong>21</strong> for more information.<br />
5 Procedure<br />
a<br />
b<br />
c<br />
Remove all grease from the repair area (minimum one inch outside the repair area) with<br />
a clean cloth soaked in cleaning agent (Material No. <strong>11</strong>-003 or <strong>11</strong>-026 ) and wipe dry<br />
with a clean cloth or absorbent paper.<br />
Mask as necessary to define the area to be plated. If the area was already plated with<br />
cadmium, the brush plating must overlap the existing cadmium by about 4 mm (0.157<br />
in), refer to Figure 001 .<br />
Brush Plating Procedure<br />
Use one of the alternative procedures given in Paragraph 2.D.(1).(d).5.d and 2.D.(1).<br />

Selected effectivity :<br />
First wet with demineralised water the bonnets set on the plating tools then<br />
squeeze with hand and paper and let soak with solution for a minimum of 2<br />
minutes.<br />
The treatment must be achieved in totality without interruption.<br />
- Manually abrade the area to be plated using a water wetted abrasive paper (180<br />
grade) or aluminum oxide powder on a water moistened swab. Feather the edge as<br />
shown on Figure 001 .<br />
- Rinse with de-mineralized water.<br />
- Electrolytically clean with deoxidizing solution (Item 16) at 10 to 15 volts forward<br />
current.<br />
- Rinse with de-mineralized water ensuring a water break free surface.<br />
- Before switching on the current, wipe the area to be treated with a pad dampened<br />
with the etching solution (Item 17) or soak a tampon with the plating solution and start<br />
the appropriate tampon movement over the plating area.<br />
- Anodically etch with solution SCM 4350 at 10 to 15 volts reverse current.<br />
- Rinse with cold clean running water.<br />
- Do not allow to dry. Before switching on the current, wipe the area to be treated with<br />
a pad dampened with the plating solution (Item 14) or soak a tampon with the plating<br />
solution and start the appropriate tampon movement over the plating area.<br />
- Using a prepared tampon move the tampon and apply plating solution at forward<br />
current or cathodic plating polarity (part (-) and tool (+)) see manufacturer's<br />
instructions (Item 14). Plate at 6 to 20 V and move the tampon in contact and over<br />
the surface and until you get the required thickness (for required ampere-hours<br />
refer to Paragraph 2.B.(1).(f).5.e . During plating move the tampon at a speed of<br />
approximately 6 to 24 m/min or 20 to 80 feet per minute. During plating do not allow<br />
the surface to dry and move the tampon to avoid the deposit to darken (burning).<br />
NOTE: For unspecified thickness the deposit must average between 0.015 mm (0.0006<br />
in) and a minimum of 0.01 mm (0.0004 in), refer to Paragraph 2.B.(1).(f).5.e .<br />
- Rinse the area with cold running water.<br />
- Apply passivating solution (Item 15) with a brush or swab to the plated surface. Allow<br />
the solution to remain in contact until a yellow or gold appearance is obtained.<br />
- Rinse the area with clean cold running water.<br />
- Dry the repair area with an air blast or with a hot air dryer at a maximum temperature<br />
of 50° C (122° F) or gently dab the surface with soft clean tissues or absorbent paper<br />
or clean cotton wool.<br />
- Inspect the treated area as described in Paragraph 2.B.(1).(e).5.d .<br />
NOTE: Make sure that the required paint coatings are applied within 16 hours.<br />
NOTE: Do not return used solutions in original containers. The solutions, rinsing water<br />
and used bonnets must be processed within the firm or destroyed by an<br />
approved organization. Contaminated packaging if not re-used with the same<br />
product is also special waste to be sent to an approved organization for recycling<br />
or disposal.<br />
