| Research Abstract |
The mast important technology to realize the micro-forming should be the application technique of them hard coating such as TiCrN, CrN, TIN, TiAIN, and DLC etc.. Results of tribo-test by ironing-type tribometer and other friction testing machine are as follows.
1)Appearances of adhesion are quite different among this hard coating dies and SKD11 die. In the case of hard coating dies, there is no relation between friction coefficient and products surface roughness.
2) DLC-Si should the lowest friction coefficient. Therefore DLC should be the best coating for micro/meso forming. But at high temperature the ability of DLC decreased.
Multi-layered DLC shows belier adhesive strength to the surface and are expedite to have belier tribo-characteristies such kinds of these coating will realize micro/meso forming in the near future.
