Cermet powder is a metallic carbide, nitride or boride powder with high-wear resistance, perfect corrosion resistance and high-temperature resistance, which is usually applied to thermal surfacing techniques, such as powder welding, oxyacetylene spraying or overlaying, HVOF/HAFA spraying, plasma transferred arc (PTA) overlaying, plasma spraying, laser overlaying, induction melting overlaying. Cemet powder is widely used in oil exploration, aerospace, mine excavation, machinery tools, marine facilities, and other fields. As hard material, it’s widely used as the thermal spray coating powder material, the welding material, the hard alloy, tungsten-carbide tools and the cermet.
