An attempt has been made to analyze the surface analysis of the black coatings using a trivalent chromium coating and nickel based ternary coating. X-ray photoelectron spectroscopy (XPS) analysis confirmed that the existence of chromates, oxides, nickel, cobalt and copper in the black coatings. From the appearance of the species at the surface, binding energy and electron level were reported. The improvement of corrosion resistance was observed with black Ni-Cu-Co using salt spray analysis.
