Functional coating and method of producing same, in particular to prevent wear or corrosion or for thermal insulation

摘要

A functional coating on a substrate, including an inorganic matrix phase composed as far as possible of a phosphate and a functional material embedded in it. In addition, a method of producing this functional coating whereby first at least one functional material is dispersed in a matrix solution including a liquid component and a phosphate, and the gelatinous dispersion thus produced is applied to the substrate in the form of a coating. Then this coating is converted by a heat treatment to the functional coating including the inorganic matrix phase and the functional material integrated into it. The functional coating described here is suitable e.g., for protection against wear or corrosion or for thermal insulation, e.g., in automotive engineering or in heating technology.
