Plasma spray can be used to produce coatings. of virtually any metallic, cermet, or ceramic ma-. terial. The coatings are used for most of the types. of applications described in a subsequent section. The transferred plasma-arc process adds to. plasma spray the capability of substrate surface heat-. ing and melting. Figure 7 is a schematic repre-. sentation of the process.
A wide variety of materials can be engineered into thermal spray coatings to provide different degrees of electrical conductivity. Materials such as copper, aluminum, and molybdenum are the most commonly used. Materials such as iron-chrome-aluminum and molybdenum-disilicide are used for higher temperature applications.
