説明
Characterization of Pt–Ir alloy coatings on a Ni-base single crystal superalloy was carried out. Pt–Ir alloys with varied composition were sputter-deposited on TMS-82+, which were then subjected to annealing and Al-pack cementation treatments. It was found that all the as-deposited films consisted of Pt–Ir solid solutioned fcc single phase, while the annealing treatment at 1423 K for 1 h drastically changed the microstructure, depending on the composition of coated layers. On the other hand, concentration profiles of alloying elements were not drastically changed by the Al-pack cementation process. It was also revealed that Ir addition increases the surface hardness of all the as-deposited, annealed, and aluminized specimens.
