摘要

Based on the results of thermochemical analysis, NH₄I+NH₄Cl proved to be a more favorable activator for codepositing Co-Al-Y compared to NH₄I or NH₄Cl. Coating deposition experiments were also demonstrated that codeposition of Co-Al-Y with high concentration of Co and minute quantities of Y could be achieved at 1323K in the NH₄I+NH₄Cl activated packs. The coating exhibited the best cyclic oxidation resistance at 1323K when NH₄I+NH₄Cl were used as activator.
