为了改善有机涂层的耐磨性，以超细Al2O3陶瓷颗粒增强环氧树脂，提高有机涂层的力学性能和物理性能。利用静电粉末喷涂环氧粉末、环氧/Al2O3、环氧粉末制备环氧/Al2O3梯度涂层，利用打分法、冲蚀试验研究了制备涂层的结合强度、耐磨性等性能。研究表明：基体经表面处理后，三层梯度涂层的结合力最强；当添加30%Al2O3陶瓷颗粒，涂层固化温度为220 ℃、时间为20 min时，涂层的耐磨性、硬度为最佳，涂层硬度可达到43 HV，用16～18目的金刚砂冲刷90 s后，涂层的磨损率仅为0.45%。

In this article， ultra-fine Al2O3 particles reinforced polymers were used to improve the mechanical and physical properties of the organic coating so as to improve its wear resistance. The epoxy-ceramic gradient coating was prepared by electrostatic spraying of epoxy powders， epoxy resin/Al2O3powders and epoxy powders sequentially. The wear resistance and the adhesion strength were studied by Scoring and erosion method respectively. It was found that the highest adhesion strength occurred on the gradient coating with three layers after surface treatment， the optimum wear resistance and hardness of 43 HV for the coating could be realized when 30% ceramic particles were added and cured at 220 ℃ for 20 min， and the wear rate of the coating， roughened by the bombardment of Al2O3 particles with the size of 16~18 μm for 90 s， was merely 0.45%.
