In the production of lithium battery materials for new energy vehicles, the components of the rotary valves experience intense friction and wear during the transportation and mixing processes, which reduces the equipment's lifespan and can even contaminate the purity of the battery materials.

Solution: Coating the components with tungsten carbide can provide wear resistance, corrosion resistance, thermal insulation, electrical insulation, surface hardening, high-temperature erosion resistance, and protection against high-temperature adhesion and damage—properties that the base material lacks. This extends the lifespan of the components and improves the overall performance of the equipment. Applying tungsten carbide coatings to lithium battery equipment significantly reduces the wear rate of the components, greatly minimizes impurities in the materials, and ensures the purity of the battery materials.
