Abstract
A method of providing a bond coat for a thermal barrier coating of a part of a turbomachine includes forming a first metallic bond coat layer on a substrate. The method also includes forming a second bond coat layer on the first metallic bond coat layer. The second bond coat layer has a porosity and a surface roughness that is greater than that of the first metallic bond coat layer. Furthermore, the method includes grit blasting the second bond coat layer to densify the second bond coat layer while substantially maintaining the surface roughness thereof.
