This standard specifies the technical requirements and test methods for low-pressure plasma lame plating nickel-cobalt-chromium-aluminum-yttrium-tantalum (NiCoCrAlYTa) alloy coatings, which are suitable for high-temperature oxidation and thermal corrosion protection of high-temperature parts of aero-engines. The standard also applies to low-pressure plasma spray-on linings of Miscellaneous MCrAlY (such as Ni, Co, NiCo, etc.). Through testing of Coating thickness, bonding strength, Hardness and anti-oxidation performance, the standard provides reliable mass assurance and technical guidance for coating applications in high temperature environments, ensuring its Stability and durability under severe conditions.
