Flame Spray Equipment
In flame spraying, the heat source is a flame generated by the combustion of a combustible gas mixed with oxygen. A sprayable material, in the form of a wire, rod, or powder, is fed into the high-temperature flame zone. It melts, is broken into tiny particles by the gas flow, and is deposited onto the surface of the product.
This method has a relatively low thermal impact on the substrate (between 50 and 150°C), allowing coatings to be applied to a wide range of materials, including plastics, wood, cardboard, and more.
Flame spray torches are made from reliable components, are very easy to operate, and require minimal installation costs. This equipment is most often used for aluminum or zinc spraying, but its overall application range is very wide.
Coating Materials
- Wear-resistant: antifriction materials (babbitts, bronzes), nickel aluminide, nichrome, or coatings containing solid lubricants
- Heat-resistant: (Ni-Al, Ni-Cr, Ni-Cr-Al, Ni-Co-Cr-Al-X, MoSi2) + ceramics with specified porosity
- Corrosion-resistant (Zn, Al, Pb, Cr, Сu, Ti)
- Optical (Co3O4, Сo2O3, Сr2O3, MoSi2)
- Electrically conductive, electrically insulating
- Sealing (Graphite or boron nitride are used as solid lubricants in AC. As the operating temperature increases, aluminum, nickel, nickel aluminide, or zirconium oxide are used as the matrix)
