Cobalt-based alloy powders: Cobalt-based alloy powders refer to a category of high-performance alloy powder materials manufactured with cobalt as the matrix and supplemented by alloying elements including chromium, tungsten, carbon and nickel. Boasting excellent properties such as high-temperature resistance, wear and corrosion resistance, thermal fatigue resistance and oxidation resistance, they serve as core consumables for surface strengthening processes like thermal spraying, plasma surfacing and laser cladding, and are widely compatible with the operational requirements of high-velocity oxygen-fuel spraying equipment (HVOF), plasma surfacing equipment and laser cladding equipment.
