Thermal spraying methods are the group of coating processes in which the material (metals, ceramics, cermet, and polymer) are fed in powder or rod or wire form to a torch where the materials are heated/melted, and accelerated towards a prepared substrate surface in the gas stream to develop a splat.

Abstract
In recent years, the demand of wear resistance material and coating is increasing very rapidly as it reduces substantial energy losses resulting from wear and friction. To overcome these energy losses, surface engineering is employed. Surface engineering is the process of coating or modifying the surface of part to minimize wear, friction, corrosion, as well as to enhance the lifespan of machine components and reduce the manufacturing cost. Recently, numerous coating methods are available for distinct material (pure metals to alloys, carbides, composites, and ceramics) applications. Hence, this chapter provides an overview on the prevention of tribo-surfaces through distinct methods of surface modification such as thermal, physical, and chemical methods of coating. Further, distinct coating properties, applications, future scope, and challenges are described.
