Abstract:
1. A method for forming an adhesion promotion bond layer between a metallic substrate having at least a metallic surface layer and a second substrate having a second surface, the method comprising: applying a surface treatment of the substrates as a self-assembly interlayer onto at least one of the surfaces, the treatment comprising using sulphur-containing molecules and forming a thiol modified surface as a coupling agent to bond chemically to both substrates and form a network structure of nanometer scale fibrils on the substrates and covering the entire treated substrate surface, wherein the thickness of self-assembly interlayer ranges between 1 Å-100 kÅ and the size of the nanometer scale fibrils in the self-assembly interlayer range from 1 Å-10 kÅ; and bringing the surfaces into sufficiently close proximity to each other for the interlayer to contact both surfaces, with the fibrils penetrating, and bonding chemically to the second substrate.
