Codeposition of Co–Al–Y on nickel base superalloys by pack cementation process
Source abstract
Abstract
Abstract Based on the results of thermochemical analysis, NH 4 I + NH 4 Cl proved to be a more favorable activator for codepositing Co–Al–Y compared to NH 4 I or NH 4 Cl. 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 1323 K in the NH 4 I + NH 4 Cl activated packs. The coating exhibited the best cyclic oxidation resistance at 1323 K when NH 4 I + NH 4 Cl were used as activator.
