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.
