摘　　要：从工程化应用的角度出发,研究了APS喷涂Cr2O3陶瓷涂层的工艺参数对涂层性能的影响.研究结果表明,粉末粒度分布、电弧电流和喷涂距离是影响涂层性能的关键因素,其他辅助条件,如抽风效果,也是获得良好结构涂层不可忽视的关键因素.所制备的性能稳定、均匀的耐磨涂层可满足激光雕刻的要求。From the point view of application in industry, the factors of APS sprayed Cr2O3 coatings were studied. The results showed that the powder size distribution, the arc current, and the spray distance has significant influence on the fabrication, micro-hardness, and wear-resistance characters of the Cr2O3 coatings. Furthermore, in this study the blowing and extraction effects of compressed air were found dominate function on the invested characters. The coating product has applied widely on the anilox product in printing and packaging industry.
