Surface Modification for Improved Properties
Almost every material in use today has a surface which is different from the material beneath the surface. For the most part, these surfaces play a useful role in the service life of the material. Such surface/bulk material combinations can be considered as composites, with surfaces ranging from a naturally occurring oxide layer protecting such metals as aluminum, titanium, and stainless steel to very deliberately tailored additions of alloying elements to attain specific desired properties, as in the cases of molecular beam epitaxy and ion implantation. In tailoring a surface, important common features are: 1) the specific property of the coating material itself, as influenced by composition and microstructure, 2) the interaction between the coating and the substrate, and 3) the problem of adhesion of the coating to the substrate, which is of utmost importance since the expected properties will be lost if the desired surface is removed. Figure 1 gives examples of phenomena which are affected by these three important features of coatings which must be addressed in any application.
