Tungsten carbide wear parts are wide used in industrial fields,including cemented carbide rolls for steel industry, mining and oil extraction tools,tungsten carbide anvils and pressure cylinders for synthetic diamonds production, tungsten carbide precision forming dies,tungsten carbide stamping dies, tungsten carbide sealing rings, various wear-resistant nozzles, surface hardened insert welding, spraying materials, etc.
Cemented carbide is with excellent comprehensive properties such as high strength, high hardness, high elastic modulus, high toughness and high wear resistance. The wear resistance of hard alloy wear-resistant parts is mainly determined by the microstructure and chemical composition of the alloy. The main structural parameters of hard alloy are: grain size and binder phase content, and the wear resistance of hard alloy wear-resistant parts is at the same time Also affected by added elements such as boron.
In the development of modern science and technology and industrial production, many important mechanical equipment and its mechanical parts are under harsh working conditions, such as high speed, high temperature, high pressure, heavy load, etc., so the mechanical parts are formed due to wear, corrosion, oxidation, etc. Damage often occurs, and most of the damage caused by friction and wear starts from the surface.
The application of surface protection measures to delay and control surface damage has become an effective method to solve the wear problem of hard alloy wear-resistant parts. Therefore, various surface wear-resistant technologies for mechanical parts have emerged, such as coating, hot-dipping, carburizing, nitriding, metallizing, thermal spraying, surfacing, coating, pasting hardened layer, high-energy beam, etc. And they have been successfully applied in hard alloy wear-resistant parts. While increasing the alloy strength and impact toughness by more than 10%-20%, the wear resistance of hard alloy wear-resistant parts has also been improved.
