摘　　要：对镁合金表面化学镀Ni-Cu-P进行改进,在其镀液中加入纳米粒子TiO_2,在镁合金AZ91D上获得耐磨耐蚀性能优良且兼具有抗菌性能的化学复合镀层。对此镀层表面形貌、组织结构、抗菌、耐磨、耐蚀性能进行了分析,结果表明:该镀层均匀、致密,结合力优良;Ni-Cu-P/纳米TiO_2化学复合镀层磨料磨损最佳耐磨性是基材的1.69倍,粘着磨损最佳耐磨性是基材的1.63倍;耐氯化钠和醋酸溶液腐蚀结果均显示该镀层具有较好的耐蚀性;抗菌性能中最佳杀菌率为99.7%,达到了理想的效果。Electroless plating of Ni Cu- Pon AZ91D magnesium alloy is improved, nano TiO2 is added in that bath, electroless composite coating of high wear and corrosion resistance and antibacterial property is obtained. The surface morphology,organization structure, antibacterial property, wear resistance and corrosion resistance are analyzed. The results show that the coating is uniform and compact, and has excellent binding force; the relative abrasive wear resistance of eleetroless composite coating of Ni-Cu-P/nano TiO2 is 1.69 times stronger than AZ91D; the relative adhesion wear resistance of electroless composite coating of Ni-Cu-P/nano TiO2 is 1.63 times stronger than AZ91D; the coating has better corrosion resistance; the antibacterial rate of best coating is 99.7%,which achieves the ideal result.
