Abstract
Temperature resistant substrates, and particularly metals such as ferrous metals, coated for corrosion resistance with coatings containing particulate metal and hexavalent chromium-providing substance can now be made further corrosion resistant, as well as having excellent heat resistance, with a coating composite. In the composite, the undercoating contains a boric acid component plus substantial amounts of finely-divided aluminum as particulate metal. As an adjacent top layer, a coating containing silica substance is used.
