摘要 | (Ni,Pd)Al coating, prepared by low pressure pack cementation on the Ni-base superalloy M38 where Pd-20 wt pct Ni alloy was predeposited, consists of a single beta-(Ni, Pd)AI phase. The initial isothermal oxidation behavior of (Ni,Pd)AI coating was investigated by TGA, XRD, SEM/EDS at 800similar to1100degreesC. Results show that oxidation kinetics accord preferably with parabolic law at 800, 900 and 1100degreesC, but not at 1000degreesC. theta-Al2O3 was observed at 800similar to1100degreesC. It is found that Pd plays an important role in accelerating the diffusion of Ti from the substrate to the coating surface in the aluminide coating. |
