准晶材料兼具硬度高、摩擦系数小、耐磨损、耐腐蚀、表面能低等特性，有着十分广阔的应用前景。但受限于本征脆性，准晶材料不能作为结构件单独使用，涂层和薄膜形态成为研究热点。综述了准晶涂层和薄膜的几种制备工艺，主要介绍了热喷涂技术、激光熔覆技术、电子束沉积技术、真空蒸镀技术、磁控溅射技术，并对这几种镀膜技术的特点进行了归纳、对比、总结。详细概述了制备过程中涂层和薄膜的生长过程、生长机理，为之后相关研究工作奠定了良好的基础。对结构和性能的研究现状及在界面结合、组织转变、后续热处理工艺中面临的问题进行了讨论，性能方面主要包括准晶涂层和薄膜优良的抗氧化、耐腐蚀、耐磨损性能及其优异的不粘性，并对存在的相关问题提出了一些可能的解决方案。最后对准晶涂层和薄膜更先进的制备方法以及准晶材料在热障涂层、不粘涂层和固体润滑剂等方面的应用前景进行了 展望。

Quasicrystal materials have both high hardness, low friction coefficient, good wear resistance, good corrosion resistance, low surface energy and have very broad application prospects. However, due to intrinsic brittleness, quasicrystalline materials cannot be used as bulk structural parts. At present, the most popular applications are concerned with coatings and thin films. This article reviews the state-of-the-art of quasicrystalline coatings and thin films, including thermal spraying technology, laser cladding technology, electron beam deposition technology, vacuum evaporation technology, magnetron sputtering technology. The growth process and mechanism of the coating and thin film in the preparation process were summarized in detail, which laid a good foundation for the related research work. The research status of structure and properties and the problems in interface combination, structure transformation and subsequent heat treatment process are discussed. The properties mainly include excellent oxidation resistance, corrosion resistance, wear resistance and excellent non viscosity of quasicrystal coating and thin film. Some possible solutions to the existing problems are proposed. Finally, the more advanced preparation methods of quasicrystal coating and thin film and the application prospect of quasicrystal materials in thermal barrier coating, non-stick coating and solid lubricant are prospected.
