发明名称 STEEL TIN PROTECTED WITH ZINC COVER AND PROTECTIVE LAYER OF CHROME AND HYDRATED BROMINE OXIDE
摘要 Steel sheet, especially suitable for car-body fabrication, galvanized and further protected by a layer of metallic chromium and hydrated oxides of chromium, electrolytically deposited. The improvement is that the metallic chromium is present in extremely fine particles that exert a very marked covering and protective effect on the underlying zinc. In this way, and with the help of the chromium oxides that further cover and protect the underlying layers, a product is obtained whose corrosion resistance is far superior to that of similar products.
