中文摘要:
      目的 通过在金属镁表面自组装MPTs 分子膜,改善金属镁的耐摩擦性。方法 采用自组装成膜技术,以MPTS 为自组装溶质,使其浸入到溶剂中制备成自组装分子膜溶液,然后吸附于镁基体表面。通过扫描电子显微镜(SEM)和自动椭圆偏振测厚仪测试了在金属镁片形成的MPTS 分子膜的形貌及膜厚范围,并进行了详细的分析。结果 随着自组装时间的延长,膜的致密性逐渐增强,力学性能得到很大的改善。当反应时间为5 min 时,MPTS 组装处于初期膜生长阶段,膜层比较疏松、多孔,此时的自组装膜还没有起到缓释作用;当反应时间延长到60~80 min 时,反应逐步趋于完全;当成膜时间达到80 min 时,已在金属镁表面形成了比较致密有序且质地均匀的MPTS 自组装分子膜。结论 通过自组装成膜技术,在金属镁表面形成性能优良的膜层,随着自组装时间的延长,膜的致密性逐渐增强,其耐摩擦性能得到进一步的完善,且其受力均匀。
英文摘要:
      The work aims to improve abrasion resistance of magnesium metal by self-assembling MPTs monolayers on the surface of magnesium metal. It was immersed in a solvent to prepare self-assembled monolayer solution with MPTS as self-assembled solute by taking advantage of self-assembled monolayer technology, and then was adsorbed on the surface of magnesium substrate. Morphology and film thickness range of MPTS monolayer formed on the surface of magnesium metal were tested by using scanning electron microscope (SEM) and auto ellipsometer and analyzed in details. With the extension of the self-assembly duration, the film compactness increased gradually and the mechanical performance improved significantly. When the reaction time was 5 min, MPTS assembly was in the initial film growth stage and film was relatively loose and porous. At this moment, self-assembled film had no sustained release effect. When the reaction time extended to 60~80 min, the reaction was gradually complete. When film formation time reached 80 min, the compact, orderly and even MPTS self-assembled monolayer formed on the surface of magnesium metal. A film layer of excellent performance forms on the surface of magnesium metal in virtue of self-assembled monolayer technology. With the extension of self-assembly duration, compactness of the film increases gradually, abrasion resistance further improves, and the film is stressed uniformly.
