Black Particles on Sintered Tungsten Part
Black Particles on Sintered Tungsten Part
(OP)
A sintered tungsten part (SAE-AMS-T-21014, Class 4) was received with a black deposit on the surface. EDAX indicates that the particles contain tungsten. The deposit is well adhere and not removed when ultrasonicallycleaned in IPA. Does anyone have an opinion as to the cause? Could the "black" material be blue tungsten oxide?

What other elements were present in the "black" layer?
