 Gas-flame sputtering of coatings. Products, technologies, equipment, materials, and staff training

Technical features:

  • material hardness, 58-63НRC;
  • microhardness, 12,2-11,8 GPa;
  • residual porosity, till 5%;
  • coating thickness, till 3,5 mm;
  • Adhesion strength, 52,0-56,0 MPa;
  • cohesion strength of coating material, 450-480MPa;
  • impact strength of material, 88-92 kJ / m2;
  • Steel dry fiction factor, 0,15-0,16
  • wear, (V = 12-14 m/s, Р = 3,2 – 3,5 MPa) 0,12- 0,14 µm / km;
  • operation temperature, till 400-420 оС.

Advantages:

  • the thickness of marked coatings is till 3,5 mm, this makes it possible to carry out repeated restoration (till 5 times) of one product for big nomenclature of details of rolling industry;
  • resistance after restoration is higher than resistance of heat-treated alloyed steels 3-7 times on depending of detail dimension type;
  • cost of detail with coating depend of thickness, marked coating, range of measuring of cost is from 0,9 till 1,4 times in comparison with the basic variant;
  • this technology ensures fiction factor 0,15-0,16 (with mean value 0,21).
