摘要： A coating process and system (20) for an article (10) having a substrate (22) formed of a metal alloy that is prone to the formation of a secondary reaction zone (SRZ) (36). The coating system (20) includes an aluminum-containing overlay coating (24) and a stabilizing layer (42) between the overlay coating (24) and the substrate (22). The overlay coating (24) contains aluminum in an amount greater by atomic percent than the metal alloy of the substrate (22), such that there is a tendency for aluminum to diffuse from the overlay coating (24) into the substrate (22). The stabilizing layer (42) is predominantly or entirely formed of at least one platinum group metal (PGM), namely, platinum, rhodium, iridium, and/or palladium. The stabilizing layer (42) is sufficient to inhibit diffusion of aluminum from the overlay coating (24) into the substrate (22) so that the substrate (22) remains essentially free of an SRZ (36) that would be deleterious to the mechanical properties of the alloy.
摘要翻译：一种用于制品（10）的涂覆方法和系统（20），其具有由容易形成二次反应区（SRZ）（36）的金属合金形成的基底（22）。涂覆系统（20）包括在覆盖涂层（24）和基底（22）之间的含铝覆盖涂层（24）和稳定层（42）。覆盖涂层（24）含有比基底（22）的金属合金大得多的原子百分比的铝，使得铝从覆盖涂层（24）扩散到基底（22）中有倾向。稳定层（42）主要或完全由至少一种铂族金属（PGM），即铂，铑，铱和/或钯形成。稳定层（42）足以抑制铝从覆盖涂层（24）扩散到衬底（22）中，使得衬底（22）基本上不含有对机械性能有害的SRZ（36）的合金。

摘要： A modified platinum group metal coating composition comprising a phase having a solid solution face-centered cubic (fcc) crystal structure, rich in platinum group materials. In order to be effective, the platinum group metal coating material was modified based on the chemical composition and chemical activity of the substrate material. The platinum group metal coating material was modified to include, in solid solution, elements of the superalloy substrate, specifically nickel (Ni) and cobalt (Co). Depending on the substrate material, the modified platinum group metal coating material may not even include Ni or Co, but may be modified to include amounts of different elements that are consistent with the chemical composition of the substrate. The modified platinum metal coating material also includes aluminum (Al). The composition may include small amounts of a second phase isolated within the fee phase matrix.
