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.
Cordierite ceramic substrates can also be used in most catalytic converters. The catalyst washcoat is a carrier for the catalytic materials, which is used to disperse the materials over a high surface area. Titanium dioxide, aluminium oxide, silicon dioxide, or a combination of silica and alumina can be used.
