The impact resistance test of tungsten cemented carbide balls is an important method to evaluate their ability to resist damage when subjected to external force impact, and is usually used to test the strength, toughness and durability of tungsten cemented carbide balls.

Tungsten cemented carbide balls are high-performance powder metallurgy products. They are primarily composed of tungsten carbide (WC), a high-hardness, refractory metal, with cobalt (Co), nickel (Ni), or molybdenum (Mo) as a binder, and are sintered in a vacuum furnace or hydrogen reduction furnace. Common series include YG, YN, YT, and YW. This material is highly valued for its excellent hardness, wear resistance, and corrosion resistance, while thermal stability is one of its core advantages in high-temperature environments.

I. Impact Resistance of Tungsten Cemented Carbide Balls 

Tungsten cemented carbide balls are made from a carbide matrix such as tungsten carbide (WC) or titanium carbide (TiC), sintered with a binder such as cobalt (Co), nickel (Ni), or molybdenum (Mo). Their impact resistance is primarily reflected in the following aspects:

Tungsten cemented carbide balls exhibit excellent fatigue resistance, which is significantly affected by composition, processing, and operating conditions. A high binder phase content, nickel-chromium additions, and optimized processing significantly enhance fatigue resistance, making them suitable for long-term stable operation under high-load, complex environments.
