Issue 47/2015 - Research on novel nano-coatings has progressed

A few days ago, the reporter learned from the Department of Science and Technology of Zhejiang Province that after more than three years of hard work, the Zhejiang Natural Science Foundation funded project undertaken by Ningbo Materials of the Chinese Academy of Sciences - the self-organizing growth and high-temperature self-lubrication behavior of V-Si-N nanocomposite hard coatings has achieved phased results, which is expected to replace the mainstream PVD (physical vapor deposition) coating technology
in the near future.

Three years ago, with the joint funding of the Natural Science Foundation of Zhejiang Province, Ningbo Institute of Materials proposed a new idea of nanostructure strengthening method for lubricating coatings in view of the shortcomings of the existing hard coating improvement method, and designed the V-Si-N nanocomposite coating
.
V-Si-N nanocomposite coatings have very good wear resistance, and their wear rate is comparable to the optimal data reported in the literature for nano-multilayer coatings and carbon-based coatings
.
In recent months, the research team has worked hard to carry out application research on V-Si-N nanocomposite coatings, and conducted high-precision cutting tests
of stainless steel with a company outside the province.
The test results show that the advantages of this coating are obvious, not only the tool life is long, but also the surface finish of the workpiece to be processed is good (up to 8 grades) and high
precision.
