Abstract
A process ( ) for applying a thermal barrier coating ( ) to a turbine component ( ) including the step ( ) of depositing a bond coating layer ( ) by, directing solid particles using a cold spray process. The layer of bond coating material may have different depths ( ) in different areas of the component ( ), and it may have different compositions ( ) across its depth. The precise control afforded by the cold spray material deposition step allows the surface of the bond coating material layer to be formed with a predetermined surface roughness or with a plurality of micro-ridges ( ) in order to optimize its bond to the overlying ceramic insulating layer ( ).
