Adhesion Aspects of Thin Films

Book excerpt: This book chronicles the proceedings of the First International Symposium on Adhesion Aspects of Thin Films, held in Newark, New Jersey, October 28-29, 1999. Films and coatings are used for a variety of purposes – decorative, protective, functional, etc. – in a host of applications. Irrespective of the intended function or application of a film or a coating, their adequate adhesion to the underlying substrates is of cardinal importance. Concomitantly, the need to understand the factors controlling adhesion and to tailor adhesion to a desired level is quite patent. This book contains a total of 16 papers, which were presented by researchers from academia, industry and other laboratories, and have been rigorously peer reviewed, suitably revised and properly edited before inclusion. The topics covered include: mechanisms, origin, evolution and measurement of stresses in thin films; surface stress effects on the intrinsic stress; various factors affecting stresses in thin films; delamination of coatings caused by residual stress; effects of surface treatments on the adhesion of metallic films; adhesion of CVD diamond to carbide cutting inserts; effect of carbon contaminant on adhesion of aluminum films; effect of interlayers on adhesion of ceramic coatings; effect of residual stress on adhesion and wear resistance of hard coatings; tribological properties of ceramic films; oxide layers as barrier coatings on a plastic substrate; adhesion aspects of organic coatings to metals; and adhesion of thin plasma polymerized fluorocarbon films.This book, providing a commentary on the current state of knowledge of adhesion of thin films, will be useful to anyone interested in thin films and will provide ideas on how to improve or tailor adhesion of a film or a coating for a given situation.
