There is a certain relationship between the wear resistance and hardness of cemented carbide, but it is not completely consistent.
Hardness refers to a material’s ability to resist scratches and dents, and is often measured using a hardness testing method. Materials with high hardness are not easily deformed when stressed, so they have better resistance to deformation. However, materials with high hardness do not necessarily have better wear resistance, because wear resistance is also affected by factors such as the toughness, fracture toughness, and surface treatment of the material. For example, high carbon steel has high hardness, but due to its poor toughness and prone to fracture and fatigue damage, its wear resistance is not necessarily better than other materials.
Wear resistance refers to the material’s ability to resist friction, wear, etc. Materials with good wear resistance usually have higher hardness and better toughness, and technologies such as surface treatment and coating can also improve their wear resistance. For example, after heat treatment, nitriding and other treatments on the surface of steel, a surface layer with high hardness and good wear resistance can be formed to increase the service life of the material.
Therefore, there is a certain relationship between the wear resistance and hardness of cemented carbide, but the specific influencing factors need to be considered comprehensively. When selecting cemented carbide, comprehensive considerations need to be made based on the actual application scenario to obtain the best wear resistance.
