Research Progress in Cutting Tool PVD Coating Material
Li Juntao;Shaanxi Institute of Technology;
With the progress of PVD coating technology,cutting tool coating material toward the direction of multilayer multi-nanocomposite from simple single binary,and become a research hotspot. Nanocomposite coatings tend to diversify the composition,the structure tends to multilayer,gradient,composite,the function of hard / soft combination. Because of its mechanical properties,high hardness,high wear resistance,high-rise combined with strength,although most still remain in the experimental stage,but has shown a good prospect.
