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.
Abstract. Trivalent Chromium Process (TCP) coatings, which have been used recently as an alternative to chromate conversion coatings (CCCs), have been characterized. The TCP coating was found to be a dense layer consisting of particles, hundreds of nm in size on the coating surface, which is similar to CCCs.bstract.
