Q:Electric hammer drill material which has several?

Because of its high hardness, very wear-resistant, has a certain strength, suitable for high-speed cutting. But the poor toughness, very brittle, in order to improve the performance of the hard alloy, with some hard carbide titanium carbide substrate in chemical vapor deposition of a layer of 5 to 7 microns (TIC) or titanium nitride (TIN), which has higher hardness. Some use ion implantation technology to inject titanium, nitrogen and carbon into the substrate at a certain depth, which not only improves the hardness and strength, but also makes them move when the drill is regrinding.
