Abstract

The modes of hypersonic metallization for the formation of coatings of aluminum on polymeric materials are selected. An empirical dependence of the sputtered aluminum particles size and the thermal-oxidative degradation temperature of the polymer is obtained. The microarc oxidation equipment has been developed for the formation of ceramic oxide coatings on the surface of aluminum gas-thermal coatings. It is found that the largest thickness of ceramic-oxide coatings is achieved when the ratio of air and propane in the atomizing air-propane mixture is from 15:1 to 18:1. The material of the sublayer (Ni) is determined, which ensures the maximum adhesion of aluminum coatings to polymers.

Keywords
