Different industrial sectors including energy generation, aerospace, manufacturing, transport and automobiles, and many others search for new protective coatings with enhanced and optimized functional characteristics such as wear-, erosion- and corrosion resistance, electrical and thermal conductivity, surface energy and others. In this context, nanocomposite (NC) coatings formed by hard nanometer-size grains in softer amorphous or polycrystalline matrices and strong grain-matrix interfaces have been found to exhibit superhardness (more than 40 GPa) and other unique and excellent elasto-plastic and tribo-corrosion characteristics.

不同的工业领域，包括能源产生，航空航天，制造，运输和汽车，以及许多其他工业领域，以及许多具有增强和优化功能特征的新保护涂层，例如磨损，侵蚀和腐蚀性，电导率和导热性，表面能，表面能和其他。在这种情况下，发现纳米复合材料（NC）涂料是由硬纳米大小的晶粒形成的，在较软的无定形或多晶矩阵和强晶型矩阵界面中形成的纳米材料（NC）涂层表现出强烈的晶粒矩阵矩阵和强晶粒式晶体，这些晶粒表现出超强（超过40 GPA），以及其他独特的和出色的Elasto and polasto and-polasto and Trasto and-polasto and Tribosto and Triposo-collososion特征。
