PVD (Physical Vapor Deposition) is a vacuum coating process in which the coating material is evaporated from a cathode and deposited onto the workpiece. The process is environmentally friendly and does not require the use of hazardous substances. PVD coatings can be single-layer or multilayer, with a gradient structure or nanostructured. Such architecture significantly improves adhesion to the substrate and increases the mechanical strength and wear resistance of the coating.<\/p>\n\n\n\n

PVD coatings:<\/p>\n\n\n\n

    \n
  • Wear-resistant, with a low coefficient of friction.<\/li>\n\n\n\n
  • Chemically inert.<\/li>\n\n\n\n
  • Attractive in appearance.<\/li>\n\n\n\n
  • Very thin and do not significantly affect the dimensions of the component.<\/li>\n<\/ul>\n\n\n\n

    Chromium-containing coatings provide corrosion protection for steels. Compared with electroplated chromium, the CrN coating process does not require the use of environmentally hazardous substances, while the wear resistance of the coating is significantly higher. <\/p>\n<\/div>\n\n\n\n

    Applications:<\/p>\n\n\n\n

      \n
    • Cutting tools<\/li>\n\n\n\n
    • Forming and punching dies<\/li>\n\n\n\n
    • Casting molds<\/li>\n\n\n\n
    • Tribological applications (rolling and sliding surfaces)<\/li>\n\n\n\n
    • Decorative products<\/li>\n<\/ul>\n<\/div>\n\n\n\n
      \n

      According to our customers, PVD coatings offer the following advantages:<\/p>\n\n\n\n

        \n
      • The service life of cutting tools increases more than threefold (Hevea AS)<\/li>\n\n\n\n
      • The service life of dies increases 3\u20134 times (Metaprint AS, Kitman Thulema AS)<\/li>\n\n\n\n
      • Elimination of lubrication for sliding guides (Efenco O\u00dc)<\/li>\n<\/ul>\n<\/div>\n\n\n\n

        Materials suitable for PVD coatings: structural steels, tool steels, alloy steels, hardmetals, copper-based alloys. PVD coatings have also been successfully tested on glass surfaces.<\/p>\n<\/div>\n\n\n\n
