Modern materials for multi-functional hardsurfacing coatings

Our materials for applying hardsurfacing coatings using physical vacuum deposition (PVD) methods are aimed at the synthesis of multi-functional coatings which, along with extreme hardness, boast a low friction coefficient, high tenacity, heat resistance, corrosion resistance, chemical inertness with respect to working material and high resistance to plastic deformation and abrasive wear.

Advantages of POLEMA S materials for hardsurfacing coatings:

  • The materials reflect current trends in the creation of multi-functional hardsurfacing coatings in metalworking, the aviation industry and power engineering.
  • The coatings make it possible to  increase the strength of cutting and stamping instruments,exponentially to perform high-speed machining without cooling medium, to increase erosion resistance and the endurance strength of machine parts.
  • A wide selection of compositions makes it possible to control the chemical composition and structure of the coatings, to synthesize multi-layer nitride, gradient and nano-structured hardsurfacing coatings for application in various spheres of metalworking, including  conditions of cyclical thermo-mechanical stress.
  • The design of sputtering targets and evaporable cathodes is adapted for various types of vacuum units and various kinds of ion-assisted coating deposition.
  • All products are made on the basisof customer's specifications. The materials used are characterised by a homogenous microstructure and vacuum tightness.

POLEMA sputtering targets and evaporable cathodes are produced from various Al-Ti, Al-Ti-Si, Cr and Al-Cr compositions
