K    However, the general term includes coatings created with not just metallic materials, but also oxides and ceramics. Deposit efficiency, bond strength, ease of operation, safety, changeover time, maintenance time and costs, appearance of the coating finish and the ability to automate the coating application affect the choice of spraying methodology. Coatings created by metal spraying range in thickness from 20 µm to several mm, depending on the conditions and methodology. Thermal spray is a process where metals, ceramic, cermet and selected polymeric materials are fed in the form of powder, wire and rods to a torch where the materials are heated or melted, and accelerated in the gas stream towards a substrate where they form a splat. This process melts pure or alloyed metal in wire form and, using compressed air, sprays the molten material at high speed onto a surface. As it is the most flexible of all thermal spray processes coatings, can be applied onto all suitable base materials with the widest variety of powders. J    The deposition rate of the surface is typically faster than other coating processes such as chemical vapor deposition and electroplating.
