Coating technology in the cutting tool, mold tool applications

In hardware store or metal cutting processing factory, we will see a gold, cobalt and copper color, black and so on seven ZaBa color bit, cutter, mould and so on, these are the coating after coating technology processing tools.
1. Golden color is plating TiN, on the tools ZrN coating. TiN is a widely used the first generation of hard material, hardness can reach 2000 hv, low friction coefficient, good impact toughness and processed materials affinity is small, not easy to form caused by adhesive wear devolop tumor, etc. ZrN hardness higher than TiN, is about 2400 hv, have certain antioxidant capacity. Stability is good.
2. The black is on the cutting tools plated with TiC/CrN coating. TiC is 2800-3000 hv microhardness and has high mechanical friction and abrasion resistance, its expansion coefficient and carbide, combined with the matrix solid. CrN coating while about 1800 hv microhardness is not high, but it has a strong wear resistance, oxidation resistance and high adhesive ability.
3. The cobalt copper is plated on the tools with TiAIN coating. TiAIN microscopic hardness up to more than 2800 hv, because of the addition of AI elements, the TiN coated tools in use process, improves the resistance to high temperature oxidation, the coating surface generated on a thin layer of AI2O3, chemical performance is stable, in order to protect the oxide coating, so TiAIN coating the working temperature can reach 800 oc.
Cutting tools, moulds and other metal tools can choose our many arc ion plating equipment. The equipment is used in hardware, glass crafts, ceramic crafts, etc., such as watches, mobile phones, metal shell, sanitary ware, cutting tools, moulds, electronic products, crystal glass, etc.
