多年来,典型的PVD涂层都是非常薄的超硬耐磨膜层,多数应用在刀具上,如钻头、铣刀、铰刀、刀片和滚刀等,也应用在各种模具上。这种应用的典型膜层厚度在1～5μm左右,当然也有特殊应用的膜层厚度接近10μm左右。然而,在汽车制造业和航空航天领域上的特殊应用膜层已经远远超过5μm。试验已经证明在这些领域里的特殊应用膜层越厚,耐磨性能和抗腐蚀性能更好。目前,有这种需要的超厚膜层可达到10～50μm左右,有
For many years, typical PVD coatings are very thin, hard-wearing layers that are used on most tools, such as drill bits, milling cutters, reamers, blades and hobs. The typical film thickness of this application is about 1 ~ 5μm, of course, there are also special applications of the film thickness of close to 10μm. However, special applications in the automotive and aerospace fields have far exceeded 5μm. Tests have demonstrated that the thicker the film for a particular application in these areas, the better in wear and corrosion resistance. Currently, there is such a need for ultra-thick film up to 10 ~ 50μm, there
