From Powder to Powerhouse: The Making of Tungsten Carbide Strips
The creation of tungsten carbide strips is a testament to precision engineering:
- Powder Metallurgy: Finely ground powders of tungsten carbide and cobalt are meticulously blended in specific ratios to achieve the desired properties.
- 누르기 및 모양 만들기: The powder mixture is then subjected to immense pressure within specialized molds, forming the initial shape of the strips.
- Sintering: The Alchemy of Heat: The pressed strips undergo a high-temperature sintering process in a controlled atmosphere. During sintering, the cobalt binder melts and fuses the tungsten carbide particles together, forming a solid, incredibly dense material.
- Finishing Touches: After sintering, the strips may undergo further processing, such as grinding, polishing, or coating, to refine their surface finish, dimensions, and enhance specific properties.
