A coating (24) suitable for use as an environmentally-protective coating on surfaces of components (10) used in hostile thermal environments, including the turbine, combustor and augmentor sections of a gas turbine engine. The coating (24) is used in a coating system (20) deposited on a substrate (22) formed of a superalloy material. The coating (24) contacts a surface of the superalloy substrate (22) and is formed of a coating material having a tensile strength of more than 50% of the superalloy material. The coating material is predominantly at least one metal chosen from the group consisting of platinum, rhodium, palladium, and iridium, and has sufficient strength to significantly contribute to the strength of the component (10) on which the coating (24) is deposited. |
