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.
It is also available as a crosslinked closed cell foam, used increasingly in aviation and aerospace applications. A fine powder grade, KYNAR 500 PVDF or HYLAR 5000 PVDF, is also used as the principal ingredient of high-end paints for metals.VDF exists in several forms: alpha (TGTG'), beta (TTTT), and gamma (TTTGTTTG') phases, depending on the chain conformations as trans (T) or gauche (G) linkages. When poled, PVDF is a ferroelectric polymer, exhibiting efficient piezoelectric and pyroelectric properties.
