Harms of Tungsten Carbide Cutting Tools WC Leaching

Harms of tungsten carbide cutting tools WC leaching reflects on bad influernce on tungsten carbide cutting tools, tungsten resources, humans and the environment. Embodied in the following three aspects:
1. Influence on tungsten carbide cutting tools. In tungsten carbide cutting tools, WC is a hard phase of it. Tungsten carbide cutting tools WC leaching will reduce hardness and wear resistance, but also lead to loss of cobalt binder, thereby decreases hardness and strength of tungsten carbide  cutting tools and dramatically shorten tools life. The impact of shortened tools life, on the one hand will bring an increase in the number of tool changes, reducing production efficiency; on the other hand will lead to increased manufacturing costs.

2. Influence on tungsten resources. Tungsten carbide cutting tools will lead to leaching of waste tungsten resources, is not conducive to the sustainable development of tungsten resources.

3. Influence on humans and the environment. Tungsten carbide cutting tools WC leaching will easily make operations workers contracted asthma, pulmonary fibrosis and allergic dermatitis and other diseases, On the other hand, Tungsten carbide cutting tools WC leaching into the cutting fluid,will cause serious environmental pollution.
