目的 利用植酸(PA)交联壳聚糖(CS)并通过超疏水改性来提升磷酸盐化学转化膜层的抗菌和防护性能,并研究超疏水改性处理对磷酸盐化学转化膜耐蚀性的影响,方法 将仿生超疏水技术和化学转化技术相结合,在镁合金基体上制备了具有超疏水和抗菌效应的磷酸盐化学转化膜。通过扫描电子显微镜、红外光谱、接触角测试、电化学测试等方法研究膜层的微观形貌、润湿性和耐蚀性。结果 SEM结果显示,通过优化PA的浓度可以使膜层更加均匀致密。接触角测试结果表明,该转化膜的接触角高达153.2°,呈超疏水性。电化学测试结果显示,相比于裸镁合金,该转化膜的自腐蚀电流密度下降了1个数量级,低频阻抗模值提高了2个数量级,展现出了卓越的耐蚀性能。结论 该膜层展现出了优异的抗菌性能和良好的自清洁性能,能够为基体提供优越的腐蚀防护效果。 |
英文摘要: |
Energy crisis, environmental pollution and other growing environmental problems have caused wide public concern, and energy conservation and emission reduction gradually become consensuses in scientific research and industrial production. As the lightest structural metal, magnesium(Mg) alloys have been widely used in a number of fields such as aviation, spaceflight, high-speed rail and automotive. However, the corrosion resistance of magnesium alloys is extremely poor, which seriously restricts their widespread use. The improvement of corrosion resistance is the key to the large-scale use of Mg alloys in the industrial field. Use of reliable surface protection coatings is an effective method to protect Mg alloys from corrosion. In addition to improving corrosion resistance, diverse service environments put forward more functional requirements for coatings. The warm and humid atmospheric environment of ocean provides favorable conditions. The formation of microbial film will not only accelerate the degradation failure of the coating, but also cause the corrosion of the substrate and shorten the service life of the equipment due to its secretion of organic acids. Therefore, the development of eco-friendly anticorrosion and antibacterial coatings has attracted more and more attention. |
