Abstract
Dispersion (or composite) coatings are among the most fascinating of the more recently developed coating systems. That said, they require no small effort to reproduce, on the industrial scale, the properties obtained under laboratory conditions. While nickel matrix composite coatings using silicon carbide or PTFE second phase are widely available as proprietary processes, other coatings using, for example, alumina, diamond, molybdenum sulphide or tungsten carbide offer interesting prospects. In the same way codeposition of propellants results in deposition of foamed coatings, while codeposition of particulate aluminium in a zinc matrix allows an alloy of these two metals to be formed.
