ABSTRACT:
A method is provided for improving the adhesion of a substrate material which does not form stable bonds to a bondable material by applying high energy bondable ions to the surface of the substrate to create an interface alloy layer and then adhering a bondable material to the surface of the substrate material. The high energy ions used may be meal ions. Before adhering, the thickness of the interface layer may be increased to form a layer utilizing conventional processes such as flame spray, plasma spray or D-gun spray. Additionally, the method may be used to join similar or dissimilar first and second substrate materials.
