cemented Carbide balls (also known as tungsten carbide balls) are widely used in precision bearings, sealing valves, oil drilling, mining tools, and other fields due to their high hardness, wear resistance, corrosion resistance, and high temperature resistance. Surface treatment is one of the key technologies for improving the performance of cemented carbide balls.

The heat treatment process of cemented carbide balls is mainly used to optimize their properties, such as improving hardness, wear resistance and fatigue resistance, while ensuring dimensional accuracy and surface quality.

The sintering process for cemented carbide balls is a key step in producing high-performance cemented carbide balls by combining refractory metal tungsten carbide (WC) with binder metal powders such as cobalt (Co) through powder metallurgy. Its core lies in precisely controlling parameters such as sintering temperature, time, atmosphere, and pressure to achieve a dense bond between powder particles, forming an alloy structure with excellent mechanical properties.

The production process of tungsten cemented carbide balls primarily involves powder metallurgy combined with precision machining techniques. The following is an overview of the carbide ball production process:
