Metal cobalt mainly plays the role of binder and alloying agent in cemented carbide.
First, cobalt is a bonding metal that can provide good toughness through plastic deformation at room temperature, thus enhancing the impact toughness of cemented carbide. During the preparation process of cemented carbide, cobalt can wet the hard phase carbide and promote the sintering of cemented carbide. In addition, cobalt also has a protective effect on the hard phase carbides in cemented carbide. It can improve the high-temperature oxidation resistance of cemented carbide, thereby allowing the cemented carbide to maintain good mechanical properties in high-temperature environments.
Secondly, metallic cobalt can also be used as an alloying agent. It forms a multi-component alloy with other metal elements in cemented carbide such as iron and nickel, which can significantly improve the strength, hardness and wear resistance of cemented carbide.
In general, metallic cobalt mainly plays the role of binder and alloying agent in cemented carbide, and it has an important impact on the performance and manufacturing process of cemented carbide.
