    Abstract: PROBLEM TO BE SOLVED: To provide a coating which is compatible with a substrate material in a turbine engine components.SOLUTION: A part 10, such as the turbine engine component, has a substrate 11 to which a coating 12 which imparts oxidation resistance to the part 10 is applied, the coating being compatible with the material forming the part. If desired, the coating 12 may be applied directly to a surface 14 of the substrate. The substrate 11 may be formed from a wide range of metallic materials including, but not limited to, nickel-based and cobalt-based superalloys. For example, the substrate 11 may be a single crystal nickel-based superalloy. The coating 12 comprises from 11 to 14 wt.% chromium, from 11 to 14 wt.% cobalt, from 7.5 to 9.5 wt.% aluminum, from 0.20 to 0.60 wt.% yttrium, from 0.10 to 0.50 wt.% hafnium, from 0.10 to 0.30 wt.% silicon, from 0.10 to 0.20 wt.% zirconium, and the balance comprising nickel.
