Flux-cored wire for surfacing corrosion-resistant and wear-resistant steel
The influence of boron carbide on the structure of a metal, deposited by a high-chromium flux-cored wire, is studied to improve the operational properties of corrosion-resistant coatings in tribological couplings. It is determined, that a martensite matrix with reduced fragments of structure, formed as a result of the separation of dispersed boride phases, increases the hardness and wear resistance of the weld metal.
