How to improve the wear resistance of tungsten carbide wear parts?

Carbide wear parts cover a very wide range, mainly including cemented carbide roll rings used in steel and other industries, synthetic diamond top hammers and cylinders, precision forming dies, precision optical dies, tungsten carbide nozzles, stamping dies, drawing dies, sealing rings, pistons, bearing journals, and surface-hardening welding and spraying materials.

The strong wear resistance of gold makes these parts products also have super wear resistance. However, the use environment of these cemented carbide wear-resistant parts requires their wear resistance to continuously improve highly. Let's take a look at how tungsten carbide wear parts can improve wear performance.



Cementedcarbide(https://en.wikipedia.org/wiki/Cemented_carbide#:~:text=Cemented%20carbide%20is%20a%20hard,composite%20by%20a%20binder%20metal.) has excellent comprehensive properties such as high strength, high hardness, high elastic modulus, high toughness and high wear resistance. Widely used in mine and oil extraction tools, industries that require high wear resistance, such as molds and wear-resistant parts. The wear performance of cemented carbide wear parts is affected by factors such as the use environment and the performance of the tungsten carbide wear parts.


The wear resistance of carbide parts is mainly determined by the microstructure and chemical composition of the tungsten carbide wear parts. The main structural parameters of cemented carbide are: grain size and binder phase content. The wear resistance of carbide parts is also affected by additive elements such as boron.


In the development of modern 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. Damage by corrosion, oxidation, etc. occurs frequently. Steel damage caused by friction and wear mostly starts at the surface. The use of surface protection measures to delay and control the damage of the surface has become an effective method to solve the wear problem of tungsten carbide wear parts.



Therefore, various anti-wear technologies on the surface of mechanical parts have emerged, such as coating, thermal infiltration, carburizing, nitriding, metal infiltration, thermal spraying, surfacing, coating (physical and chemical vapor deposition, separation (sub-plating), paste hardening layer, high-energy beam (laser or electron beam cladding, ion implantation), etc. Diluted metal has been successfully used in tungsten carbide wear-resistant parts. While improving carbide strength and impact toughness by more than 10%, the wear resistance of tungsten carbide wear parts wear-resistant parts has also been improved.


Surface protection of tungsten carbide parts to control surface damage is the most effective way to solve the wear problem of TC wear parts. LANGSUN CARBIDE has a variety of surface strengthening technologies, such as plasma surfacing welding, supersonic spraying, gas shielded welding, vacuum cladding, etc., can better protect tungsten carbide wear-resistant parts and prolong the service life.
