Modern materials for multi-functional hardsurfacing coatings
Our materials for applying hardsurfacing coatings using physical vacuum deposition (PVD) methods are oriented toward the synthesis of multi-functional coatings which, along with extreme hardness, boast a low friction constant, high tenacity, heat resistance, corrosion resistance, chemical inertness with respect to working material, and high resistance to plastic deformation and abrasive wear.
Some advantages of POLEMA 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 dramatically increase the strength of cutting and stamping instruments, to perform high-speed metalworking without metal-working oil, to increase erosion resistance and the endurance strength of machine parts.
- A wide selection of compositions makes it possible to control the chemical makeup and structure of the coatings, synthesize multi-layer nitride, gradient, and nano-structured hardsurfacing coatings for application in various spheres of metalworking, including under conditions of cyclical thermo-mechanical stress.
- The design of sputtering targets and evaporable cathodes is aimed at various types of vacuum units and various kinds of ion-assisted coating deposition.
- All products are made based on the customer's specifications. The materials used are marked 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
