Abstract:
A method for use in a physical vapor deposition coating process includes depositing a ceramic coating material from a plume onto at least one substrate to form a ceramic coating thereon, and during the deposition, rotating the at least one substrate at rotational speed selected with respect to deposition rate of the ceramic coating material onto the at least one substrate.
Abstract:
A thermal barrier coating is applied to a turbine engine component having a substrate. The thermal barrier coating has a first layer which has a strain tolerant columnar microstructure at an interface with the substrate for spallation resistance and a second layer which is porous conduction and radiation thermally resistant at an outer surface of the thermal barrier coating.
