摘要：
To improve the oxidation resistance of γ-TiAl alloys, Ti-43Al-5Cr(L10) alloy substrates were coated with the L12-(Al,Cr)3Ti layer by pack cementation. Coatings were formed by immersing the substrate in a mixture consisting of 90% Ti-61Al-14Cr(L12) alloy powders and 10% Al2O3 powders, without activators, and then heating in an alumina boat under a vacuum of approx. 10-4Pa for 1-96 h at 1423 K. The coating layer for γ-TiAl alloys was effectively formed by surface diffusion and bulk diffusion of aluminum, titanium and chromium from pack alloy powders. The coating consisted of the two diffusion layers, an outer L12-phase layer and an inner L10-phase layer. The coated alloy showed a remarkable improvement in the oxidation resistance over the uncoated TiAl alloys.
