Mobile robotic universal platforms for applying metallization, protective and specialized coatings using hypersonic metallization.
  • Formation of high density wear-resistant coatings of increased density with a productivity of over 16 kg/h;
  • Application of corrosion-resistant coatings over large areas (100 – 1000 sq. meters);
  • Using hypersonic metallization instead of galvanic chromium plating;
  • Application of coatings to protect housings of radio-electronic equipment from electromagnetic influence;
  • Application of steel coatings on aluminum and magnesium details;
  • Application of bactericidal coatings;
  • Application of decorative coatings;
  • Application of heat-resistant coatings.

Conventional electrometallization

(jet speed = 170 m/s)

Hypersonic metallization

(jet speed = 1200-1500 m/s)

The adhesion strength to the base is up to 60 MPa, which is twice as high as with conventional metallization and spraying;

Porosity of steel coatings is 1-4% compared to 8-12% for conventional metallization

Technology of applying antifriction and protective coatings by gas-flame spraying of thermoplastic polymer powders
Purpose:
  • Long-term protection of details and structural elements from exposure to aggressive environments and abrasive wear;
  • Application of antifriction layers;
  • Electrical insulation of connections of electrical power fittings;
  • Isolation of contacting dissimilar metals to avoid electrochemical processes;
  • Application of corrosion-resistant electrically insulating coatings with improved mechanical properties to connecting fittings of pipelines for transporting flammable products.
Advantages and efficiency:
  • Ease of implementation of the process, the possibility of applying coatings to structural elements without disassembling them;
  • Wide range of applied polymeric materials;
  • Application of coatings to metals, ceramics, glass;
  • The hydrospray gun is one of the lightest in its class.
