Self-fluxing powders

Self-fluxing alloys are universal and widely used materials in the technique of creating wear-resistant and resistant to chemical corrosion and oxidation coatings. The alloys are alloyed with boron and silicon, forming low-melting fluxes when the coating material interacts with the surface of the sprayed part. Boron and silicon reduce the melting temperature of the coating and increase the fluidity of the melt, and the presence of chromium boride solid and complex carboborides in the composition of the alloys provide the hardness and wear resistance of the coating.

Self-fluxing powder

Powder self-fluxing alloys of the Ni-Cr-B-Si system, in which carbides and borides of refractory metals (tungsten, vanadium, chromium, molybdenum) are often added to form composite alloys with higher physical-mechanical properties.
