This article presents the major thermal spray processes and their subsets, presenting each of the commercially significant processes together with some of their important variations. Each process is presented along with the attributes that influence coating structure and performance. The article summarizes the essential equipment components and necessary controls. The various thermal spray processes are conventional flame spray, detonation gun, high-velocity oxyfuel spray, electric arc spray, and plasma arc spray. Other processes, such as cold spray, underwater plasma arc spray, and extended-arc and other high-energy plasma arc spray, are also considered.

This article describes the process of selecting an optimum coating and material system for a specific application. It reviews critical coating functions that influence the coating selection process, and presents some application success stories. The article explores the benefits of thermal spray coatings and functions they provide. It also presents key references from various National Thermal Spray Conference, United Thermal Spray Conference, and International Thermal Spray Conference Proceedings from 2006 through 2012.

Significant expansion of thermal spray technology occurred with the invention of plasma spray, detonation gun, and high-velocity oxyfuel (HVOF) deposition technologies. This article provides a brief history of the major initiating inventions/developments of thermal spray processes. It provides information on feedstock materials developed for specific thermal spray processes.
