Surface Engineering for Coating: A Smart Technique (original) (raw)

Advanced Surface Coating Techniques for Modern Industrial Applications, Publisher: IGI Global, 2020

Abstract

Surface engineering defines the enhancement of certain properties of the surface of a component. Two main concern of surface engineering are (1) to increase the wear resistance or damage resistance of the component, and (2) to modify its frictional behavior. The components which enhance the response can be suitably design by the knowledge of surface engineering to exhibit a combination of properties that provides a more favourable tribological response. However, the properties of the surface engineered layer and the properties of the substrate is not only the crucial things, but also the properties of the interface, which can be classified as being either sharp or diffuse. Surface engineered component is not only associated with the behaviour of the surface material, but also with the material below the surface. Today, there are many different Surface engineering techniques available; starting from vacuum to atmospheric pressure, wet to dry, simple to sophisticated, and low-cost to high-cost to obtain the required purposeful distinctiveness of material. Most methods used today are dry and thus environmentally sound. This chapter describes various types of coatings over materials to get an overall idea of the technique keeping prime focus on graduate and undergraduate students.
