摘要
Abstract
The structure change was observed and analyzed for the aluminidecoating on a representative Co-base superalloy DZ40M during high-temperatureo xidation in air. It is discovered that, this coating, which is prepared by low-p ressure chemical vapor deposition (LP-CVD), degrades mainly by oxidation on the surface of the coating at 900℃, but mainly by inner-diffusion of Al inward to the substrate at 1000℃.关键词
