Corrosion resistance of multilayer coatings deposited by PVD techniques onto the brass substrate

The paper presents investigation results of the structure and corrosion resistance of the CuZn40Pb2 brass deposited by PVD process with the thin multilayer Ti/CrN, Ti/ZrN, Ti/TiAlN, TiAlN/Mo coatings. The corrosion tests were made in a 1 M HCl solution. It was found out that coatings deposited by PV...

Description
Summary:The paper presents investigation results of the structure and corrosion resistance of the CuZn40Pb2 brass deposited by PVD process with the thin multilayer Ti/CrN, Ti/ZrN, Ti/TiAlN, TiAlN/Mo coatings. The corrosion tests were made in a 1 M HCl solution. It was found out that coatings deposited by PVD method on the brass substrate improve significantly its corrosion resistance. It has been demonstrated that the increase of the number of layers results in a significant increase of the corrosion resistance. The best results were obtained for the multilayer Ti/ZrN and Ti/CrN coatings.
