A process (20) for applying a thermal barrier coating (51) to a turbine component (50) including the step (34) of depositing a bond coating layer (56) by, directing solid particles using a cold spray process. The layer of bond coating material may have different depths (80,82) in different areas of the component (50), and it may have different compositions (60,62) 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 (86) in order to optimize its bond to the overlying ceramic insulating layer (52).

1. A method of applying a thermal barrier coating comprising the steps of:providing a substrate material; directing solid particles of bond coating material toward a surface of the substrate material at a velocity sufficiently high to cause the particles to deform and to adhere to the surface to form a layer of bond coating material; applying a layer of ceramic insulating material over the layer of bond coating material.
