Tungsten Carbide-Cobalt and Nickel Alloy Blended PowderEutectic®29123• Ideal for boiler coal chutes and induced draft fan blades• Designed to resist to fine particle abrasion and erosion• Suited for use with cold spray and non tranferred arc processes

DESCRIPTION:Eutectic 29123 is a blend of an atomized Tungsten carbide/cobalt and Nickel alloy powder. It has been specificallydesigned to provide resistance to fine particle abrasion anderosion. Coatings of 29123 are ideally suited for utility boilercoal chutes and induced draft fan blades. The TeroDyn®2000, TeroDyn ® 3000, CDS8000 Systems as well as NontransferredPlasma Arc can be used to allpy 29123 powder.A bond coat is required to ensure good adhesion to the basemetal. Eutectic 21031 or 18995 are the alloys preferred forbond coating in most applications.FINISHING PROCEDURES:Use of Eutectic 29123 in the as-sprayed condition isrecommended. If finishing is necessary, please use thefollowing guidlines...Grinding Wheel Type: Green Silicon CarbideGrit Size: 60 - 80Grade.: H (soft)Structure: 5Bond Type: VitrifiedWheel Speed: Use Manufacturer’s RecommendationWork Speed: 50 - 65 surface feet per minuteTraverse SpeedRoughing: 5-15 inches per minuteFinishing: 3-8 inches per minuteIn-FeedRoughing: 0.001 inches per passFinishing: 0.0005 inches per pass or lessCoolant: Flood coolant with rust inhibitors in 2-5%concentrationNotes:1. Before grinding, all edges and ends of coating must be chamfer ground.2. Frequently dress the grinding wheel face to reduce friction and heat.TECHNICAL DATA:Coating Properties:Macro-Hardness: Rockwell C scale 50Micro-Hardness of Carbide: Rockwell C scale 75Density: 11 g/cc (TeroDyn Systems)11.3 g/cc (Plasma Systems)Maximum Service Temperature: 1200°F (649°C)Powder Properties:Hall Flow Rate: 12.9 secondsBulk Density: 5.2 g/ccPowder Coverage: 0.071 lbs/ ft 2 @ 0.001”APPLICATIONS:• Fan Blades• Coal Chutes• Pump Housings• Polishing Fixtures• Drilling Fixutres• Grain ChutesRECOMMENDED COATING AND SPRAY PARAMETERS:TD 2000Nozzle RL 200RotoJetRSF-1@10 psiModule Adaptor Yellow/RedOxygen*50 psi / 30 flowAcetylene/Propylene* 12 psi / 60 flowT-Valve Setting 10-12 clicksCoating Rate16 lbs/hrSpray Distance 7-9 inchesCoating Efficiency 90%* FM-1 flowmeterTD 3000Nozzle RL 200Oxygen50 psi / 32 flowAcetylene12 psi / 48 flowCarrier Gas (Nitrogen) 55 psiCoating Rate15 lbs/hrTerometer 90Spray Distance 7-9 inchesCoating Efficiency 90%CDS 8000Oxygen 4 bar58 psiAcetylene 0.7 bar 10 psiAir 0.7 bar10 psiModule Adaptor 3SSM 10Spray Distance 8 inchesYOUR RESOURCE FOR PROTECTION, REPAIR AND JOINING SOLUTIONSEutectic CorporationN94 W14355 Garwin Mace DriveMenomonee Falls, WI 53051 USAP 800-558-8524 • F 262-255-5542www.eutectic.comEutectic Canada428, rue Aime VincentVaudreuil-Dorion, Quebec J7V 5V5Phone: (800) 361-9439Fax: (514) 695-8793www.eutectic-na.comEutectic MexicoKM 36.5 AutopistaMexico-Quertaro54730 Cautitlan-IzcalliEstado de Mexico, MexicoPhone: 011 (52) 55-5872-1111e-mail: eutectic@eutectic.com.mxStatement of Liability: Due to variations inherent in specifi c applications, the technical information contained herein, including any information as to suggested product applications or results, is presented withoutrepresentation or warranty, expressed or implied.
