ANP PRQJECT QUARTERLY PROGRESS REPORT Pd-3% Mn alloy. As a result of this investigation, it was found that a brazing alloy in contact with one base metal may be severelyoxidized, whereas it may be relatively unattacked when in contact with another base metal. This might be explained by the fact that the least oxidation -resistant constituents of the brazing alloy may diffuse more readily into certain base metals than into others. Corrosion af Braz%ng Alloys by Sodium Hydroxide. Since A nickel is relatively unattacked by molten sodium hydroxide at 15Q0°F, it serves as a suitable base metal for testing the corrosion resistance of brazing alloys in this medium. Examination of a joint brazed with 60% Pd-40% Ni alloy and tested in NaOH for 100 hr showed 168 that no attack is present. Several other alloys were attacked, and the joints brazed with the Cr-Ni-Si-Mn and the Cr-Ni-Si alloys fractured during removal from the test capsule. Corrosion of Brazing Alloys by Sodium and Li thiom. Because brazing operations may be proposed for as- sembling fuel plates into subas- semblies for certain types of reactors, it was of interest to study the static corrosion resistance of brazed joints in contact with sodium or lithium. The 60% Pd-4QX N i alloy, which ex- hibited excellent corrosion resistance to all other media tested, was severely attacked by the liquid metals. The extreme attack of sodium on brazed Inconel is illustrated in Fig. 12,7, which is the photomicrograph of a Fig. 12.7. Inconel Brazed with 60$ Pd-4Q% N i After 100 hr at 15QO0F in Sodium, Etched with aqua regia. 15QX.
