Surface engineering is a multidiscipline activity aimed at tailoring the properties or surfaces of engineering materials to improve their function or service life. As applied to metals, surface engineering includes processes such as plating, diffusion treatment, physical and chemical vapor deposition, ion implantation, thermal spray coatings, selective hardening, hardfacing, and a variety of less-used and proprietary processes. These processes will be described briefly and it will be shown that each process has a niche where it works better or is more cost effective than competing surface engineering treatments or bulk materials. This paper will review the various forms of wear that occur in industrial environments. Techniques will be described to match available surface engineering processes with wear situations. The goal is to present selection guidelines for machine designers and industrial operating personnel on the use of surface engineering to solve wear problems.
