Compared with cemented carbide, steel-bonded cemented carbide has better impact resistance and higher strength. One of the reasons is that the TiC cermet alloy contains a relatively high proportion of hard phases, which can significantly increase the hardness of the alloy. In addition, the hard phase has some unique properties, such as: the hard phase and the friction surface are non-metallic contact in the application process. Therefore, the friction coefficient between moving parts is significantly reduced, the probability of cold welding phenomenon is reduced, and finally the workpiece has less destructive and higher wear resistance.
In addition to high compressive strength, rigidity, flexural strength and elastic modulus, TiC steel-bonded alloys also obtain high toughness, that is, deformability. In addition, its high specific strength, low specific gravity, heat treatment expansion coefficient similar to steel, and high damping characteristics all play an important role in the application process. For TiC-based steel alloys, it also has these advantages of steel alloys.
