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.

不同的工业部门，包括能源发电、航空航天、制造、运输和汽车等，都在寻求具有增强和优化功能特性的新型防护涂层，例如耐磨、耐侵蚀和耐腐蚀、导电性和导热性、表面能等。在此背景下，由较软的非晶或多晶基体中的硬纳米尺寸晶粒和强晶粒-基体界面形成的纳米复合材料（NC）涂层被发现表现出超硬度（超过40 GPa）和其他独特且优异的弹塑性和摩擦性能-腐蚀特性。
