发明名称 SMOOTH OUTER COATING FOR COMBUSTOR COMPONENTS AND COATING METHOD THEREFOR
摘要 A coating and method for reducing the incidence of cracking in a combustor assembly of a gas turbine engine, and particularly combustor assemblies of at least two components that are welded together to define a weld region that is prone to cracking at combustion temperatures sustained within the combustion chamber of the gas turbine engine. At least the surface of the weld region protected by a coating system comprising a thermal-sprayed metallic bond coat and a ceramic coating deposited on the bond coat. The ceramic coating is deposited by thermal spraying a powder having a particle size of not greater than 10 micrometers, and the outer surface of the coating system is smoother than the outer surface of the bond coat on which the ceramic coating is deposited.
