【摘要】 以水作为分散介质,制备了含丙烯酸树脂和MoS₂颗粒的分散液;以阳极氧化为前处理,采用电化学共沉积法在镁合金表面制备了MoS₂/树脂杂化膜层。膜层的摩擦磨损性能采用MR-060型多功能摩擦磨损试验机考察,并分析了膜层的磨损机制;采用PARSTAT2273电化学工作站进行了电化学阻抗谱（EIS）及极化曲线（PD）测试;利用FE-SEM和EDS分析了膜层结构及形貌。结果显示:膜层厚度高达50μm;在3.5wt.%NaCl溶液中,表现出优良的耐腐蚀性能;MoS₂的加入,有效的降低膜层的摩擦系数,提高耐磨损性能;此杂化膜层价格低廉、无毒、不燃,可作为一种全新、有效的GW103K镁合金防护膜层。更多还原

【Abstract】 With water as dispersion medium,MoS₂/resin hybrid coatings were prepared by electrochemical deposition on the magnesium alloy.Friction and wear properties of the film were investigated using MR-060 Multifunctional friction and wear testing machine.The electrochemical performance of the coating was evaluated by PARSTAT2273 electrochemical workstation;surface morphologies were analyzed using FE-SEM and EDS.The results show that the thickness of the film is up to 50μm.MoS₂ particles dispersed pretty well in the matrix of resin and the MoS₂/resin hybrid coating has very good corrosion resistance and wear resistance.It’s a rather effective film with very good prospects for magnesium alloy.更多还原
