The coating is doped with Al2O3, TiO2, and β-Sialon nanomaterials, forming an Al2O3/TiO2/β-Sialon ternary composite coating. Al2O3/TiO2/β-Sialon nanoparticles were prepared using the sol-gel method, and the composite coating was made by thermal spraying technology. The surface morphology, structural properties, and optical properties of the composite coating were analyzed.The results show that the composite coating prepared by this method has high hardness and wear resistance. Its wear and friction coefficients are reduced by more than 10% and 20%, respectively, compared to a single coating. In addition, the surface roughness of the composite coating is significantly reduced, and the optical transmission rate and anti-ultraviolet properties are also improved.Keywords: composite coating; sol-gel method; nanoparticles; friction performance; optical properties.一、讨论背景传统涂层材料的磨损、耐热、耐腐蚀性能较差，不能满足高负荷、高温、复杂工况下的使用需求。近年来，随着纳米技术的进展，人们开精品文档---下载后可任意编辑始讨论纳米粒子掺杂的复合涂层。纳米粒子具有独特的物理、化学性能，能够改善涂层的机械性能、耐热性、稳定性、光学性能等。Al2O3/TiO2/β-Sialon 复合涂...
