Abstract
Studies were carried out to develop silicide based oxidation resistant coatings over Mo-30W alloy substrate
employing halide activated pack cementation coating process. Effect of activator content and temperature on
coating was studied. Coated samples were characterized for phase and microstructure evaluation by SEM and
EDS. Cyclic oxidation tests on coated alloy were performed at 1000oC up to 50 h. The coating provided enough
protection from oxidation.
