Thin-layer plastic coatings applied to various parts and articles have excellent anti-corrosion and, in the case of some plastics, high anti-friction properties. There are many different ways of applying thin plastic coatings, for example gas-flame, jet spray, vibrational, centrifugal, vortex and others. Of these, the method most widely used both at home and abroad is that of applying finely-dispersed powdered plastic to the surface of the part or article. In this method, the metallic article is heated to a temperature somewhat higher than the melting temperature of the powered polymer and charged into a tank containing a suspension of the powder. On coming in contact with the heated surface of the article the polymer melts and, with additional heating, flows over the surface, forming a continuous uniform coating.
