Wear resistant anticorrosive diamond-like carbon coatings for moulds intended to cast items from plastics


Diamond-like carbon (DLC) coatings are applied by the pulsed cathodic arc plasma deposition on casting moulds in vacuum. Hydrogen-free diamond-like carbon coatings are characterized by perfect physical and chemical properties owing to perdomination of diamond-type bonds between carbon atoms. The method of the pulsed cathodic arc deposition in vacuum is patented. The coatings significantly improve surface quality and extend casting mold service life.

Specification:
incease in wear resistance of moulds up to 5 times
chemical resistance to action of thermoplastic and thermoset materials and corrosion preventing
no-sticking of plastic to mould sides
heat resistance up to 350°C
