Superhard Materials Research and Application of Thin Film Coatings
iN / NbN nanocomposite multilayers hardness is to 51GPa. The TiYN / VN nano-composite multilayer films competing high hardness 78GPa, close to the diamond hard \Recently, nanocrystalline composite TiN / SiNx film hardness reached a record 105GPa, can be said to fully meet the hardness of diamond. This surprising result has been the same research group,[link widoczny dla zalogowanych], different researchers and different research groups repeating have proved correct. This may be the first to obtain the hardness can be compared with the super-hard diamond film material. The meaning is obvious. Why is access to the hardness of diamond on the interpretation of the findings is not entirely convincing. Some people think that in the case of nano-multilayer films, the nano-multilayer interface effectively prevent the dislocation slip, the crack is difficult to extend, causing the anomalous increase in hardness. Nanocrystalline composite films in the case of TiN film may be nano-grains in the grain boundaries and highly dispersed nano-particles SiNx coherent strain around the place due to strengthening effect caused a sharp increase in hardness. Whether the above theoretical explanation is totally reasonable, this nano-composite multilayer films and nano-grain composite film is very bright prospect. Nanocomposite multilayers not only very hard,[link widoczny dla zalogowanych], low friction coefficient, so is the ideal tool (mold) coating material. Their emergence as the most hard to Diamond status of the material poses a severe challenge. At the same time there are also economic advantages are obvious, so it has a very good market prospects. However, due to some technical problem is not resolved, yet being widely used in industry. Can imagine with the technology to mature, these materials may prompt access to industrial application. Although sodium and sodium m m grain multilayer composite membrane has the highest hardness of the diamond position poses a severe challenge, but I see it, I think that they can not completely replace the diamond. Diamond film is a remarkably versatile multi-functional materials, application is not limited to superhard materials. And the thickness of diamond film can be made into a large (more than 2mm) of the self-supporting film, the nano-composite multilayer films and nano-composite film, it is impossible in any case.
