  • Publication number: 20120228124
    Abstract: A method of depositing wear resistant layers, using PVD method, where the depositing is carried out from at least two working deposition sources, simultaneously, where at least one of said sources is a cylindrical rotating cathode working in an unbalanced magnetron regime and simultaneously, at least one of said sources is a cathode, working in low-voltage arc-discharge regime. Further, the invention is related to the apparatus for carrying out said method, the apparatus consisting of vacuum deposition chamber, in which there are at least two deposition sources with their relevant gas inputs of process gases and their shields, and in which at least one substrate on rotating support is placed, and where the most substantive is that at least one of said sources is a cylindrical rotating cathode working in an unbalanced magnetron regime, and, simultaneously, at least one of said sources is a cathode, working in low-voltage arc-discharge regime.
