Preparation method: 
1. High temperature melting method involves melting cobalt and boron sources (such as elemental boron, boron iron, B ₂ O3, etc.) together under vacuum or protective atmosphere to alloy them. 2. Direct synthesis: Mix cobalt powder and high-purity boron powder in a 1:1 ratio, react in an argon atmosphere at 1000-1100 ℃ for 2-3 hours, cool and grind for purification. 
3. Reduction boronation: Mix cobalt oxide and boron anhydride, use magnesium/aluminum as a reducing agent for high-temperature reduction, and remove impurities by acid washing to obtain pure product. 
4. Gas deposition: Cobalt salt+boron source gas is used to deposit CoB thin films on the surface of the substrate, which are compatible with the coating. 
Purpose: 
1. Manufacturing of Cemented Carbide: 
Cemented Carbide composed of boron cobalt and other metals such as tungsten and titanium have excellent wear resistance and high temperature stability, and are widely used in cutting tools, drill bits, abrasives, and other fields.
