Tungsten carbide production has been a cornerstone in the development of cutting tools, transforming the industry with its exceptional hardness, wear resistance, and thermal stability. This article delves into the impact of tungsten carbide on the cutting tool industry, exploring its applications, production processes, and future prospects.
Introduction to Tungsten Carbide
Tungsten carbide is a compound of tungsten and carbon, known for its hardness, which is second only to diamond. It is widely used in the manufacture of cutting tools due to its ability to withstand high temperatures and maintain sharpness over time. The production of tungsten carbide involves blending tungsten carbide powder with metallic binders like cobalt, followed by sintering at high temperatures to form the desired shape and structure.
Production Process of Tungsten Carbide
The production process of tungsten carbide involves several key steps:
1. Material Preparation: Tungsten carbide powder is mixed with a binder, typically cobalt, to enhance its toughness while maintaining hardness.
- Mixing of Tungsten Carbide Powder with Cobalt
- Pressing and Sintering
- Grinding and Shaping
2. Pressing and Sintering: The mixture is pressed into the desired shape and then sintered in a vacuum or hydrogen reduction furnace at temperatures around 1400°C to achieve the required hardness and structure.
3. Grinding and Shaping: The sintered carbide is then ground and shaped using diamond tools to achieve precise dimensions and edge geometry.
4. Coating: Some tools may undergo additional coating processes to enhance wear resistance and tool life.
