Definitions
- a process for coating a gas turbine engine component includes applying a bond coat on a superalloy substrate of a component; applying a thermal barrier material to said bond coat; mixing a rare earth apatite and a rare earth zirconate to form a randomly dispersed system; and applying said randomly dispersed system to said thermal barrier material via Suspension Plasma Spray (SPS) or Precursor Plasma Spray (SPPS).
- SPS Suspension Plasma Spray
- SPPS Precursor Plasma Spray
- the bond coat 46 may be applied by any method operable to produce a dense, uniform, adherent coating of the desired composition, such as, but not limited to, an overlay bond coat, diffusion bond coat, cathodic arc bond coat, etc.
- Such techniques may include, but are not limited to, diffusion processes (e.g., inward, outward, etc.), low pressure plasma-spray, air plasma-spray, sputtering, cathodic arc, electron beam physical vapor deposition, high velocity plasma spray techniques (e.g., HVOF, HVAF), combustion processes, wire spray techniques, laser beam cladding, electron beam cladding, etc.
