| Detailed Product Description： | Plasma thermal spraying is a particular material will be melted by the heat source after discharged into the substrate surface, thereby forming a functional technical surface layer. By selecting different materials, coatings can achieve different functions, such as: corrosion resistance, abrasion resistance, high temperature, seals, insulation, electrical conductivity, insulation and so on. Plasma spraying is a versatile spray equipment, can be sprayed almost all thermal spray material, because of its up to more than ten thousand degrees flame temperature to melt the high melting point materials such as ceramics, so it is widely used in the spraying of ceramic materials. Plasma sprayed coatings prepared roles include: corrosion resistance, high temperature, thermal insulation, corrosion resistance, plasma, insulation. Tungsten - carbon binary system can form two crystal carbide, namely WC and W2C. WC carbide which is the main raw material for the manufacture, preparation of high wear-resistant coating is also an important raw material in the field of thermal spray powder. WC high hardness, particularly its high-temperature hardness. WC can be well wetted by C0, Ni, Fe and other metal melt, especially preferably the solution of cobalt are wettability. When raising the temperature to above the melting point of the metal, can be dissolved in these circles mouth molten metal, and when the temperature decreases, but also the precipitation WC0 these excellent properties, it can be drilled or nickel binder phase made of metal material, or covered by high-temperature sintering process to form a good abrasion wear-resistant coating. The main disadvantage is the high temperature oxidation of WC ceramic spray processing ability is poor, suffered severe oxidation at 500 ℃ ~ 800 ℃ seven air, easily decomposed by the intense heat and carbon for W2C, the so-called "lost carbon" test resistance in the atmosphere. This phase of the WC particles are pre-protected by a metal heat antioxidant do wrap coat or tie; also with TaC, TiC, such as the solution to form a composite carbide ceramic coating to improve the thermal oxidation resistance of WC. WC was heated to 2850 ℃ remained stable in an Ar atmosphere, in a high temperature nitrogen gas is also affected. W2C melting point and high hardness than WC, W2C ten WC eutectic mixture capable of forming a ceramic coating process and WC, lowering the melting point, easy to cast, so-called "cast tungsten carbide" or "fusible tungsten carbide" ceramic coating, which The average carbon content of 3.8% to 20% (mass>, which contains W2C 78% to 80% |
