摘　　要：以结晶度为衡量指标,通过正交试验确定了火焰喷涂超高分子聚乙烯(UHME-PE)的较优工艺参数,采用氮气侧吹冷却技术使涂层的结晶度降低了13.93%,涂层结合强度提高了16.42%;对UHME-PE涂层耐磨粒冲蚀机理进行了初步探讨。UHMWPE coating was produced by flame spraying, and the best of process parameters were determined by the crystallinity index of UHMWPE. The crystallinity of the coating, which was prepared by Side-blown using nitrogen cooling technology, is reduced to 13.93%, and the bond strength the coating is increased to 16.42%.The abrasive erosion mechanism of UHME-PE coating was discussed.
