Will the coating operate in high temperatures ?

Various coatings have been designed to run at temperatures greater than 1000 degrees C. The two main deposits employed are Thermal Barriers (TBC’s) and MCrAlYs (where M is Co, Ni, or Fe). Thermal barriers are designed to create a temperature gradient across the coating. These allow parts with a coating to work at high temperatures where they would otherwise soften or melt. The MCrAlY deposits are designed to improve oxidation and sulphidation resistance or part running in fuel rich high temperature environment.
