摘要金属腐蚀一直是困扰人类社会生活的一个大问题。许多看似很大的灾难其实起因都是因为零部件被腐蚀才导致发生的。仅我们国家而言,每年被腐蚀的钢就占到了每年钢产量的10%左右,造成的经济损失更是不可想象,对社会资源也是一种极大的浪费。86713
本文针对上述问题,通过调节g-C3N4/TiO2复合涂层的热处理工艺,改善优化g-C3N4/TiO2涂层的光电防腐蚀性能。采用不同煅烧温度和不同煅烧时间的g-C3N4/TiO2粉末,加入环氧固化等添加剂制备g-C3N4/TiO2复合涂层,经涂覆制备不同煅烧温度,不同煅烧时间,不同稀释剂的g-C3N4/TiO2复合涂层并进行相关测试;使用电化学工作站,扫描电子显微镜、XRD和接触角等测试手段对复合涂层进行表征,评价其结构及抗腐蚀性能;通过分析不同反应条件对产物的结构和抗腐蚀性能的影响,涂层最佳结构和抗腐蚀性能最优条件。研究表明:350度,煅烧2。5小时的条件下,样品耐腐蚀率最高。

Abstract Metal corrosion has been a serious problem for human social life。 In fact, many seemingly great disaster because the causes that led to parts corrosion occurs。 Only our own country, the annual corrosion of steel accounted for about 10% of annual steel production, economic losses is unthinkable, social resources is a tremendous waste。
In this paper, aiming at these problems, by adjusting the g-C3N4/TiO2 composite coating of heat treatment process, optimizing the g-C3N4/TiO2 photoelectric corrosion protection performance of coating。 Adopt different calcination temperature and calcination time g-C3N4/TiO2 powder, adding epoxy curing additives such as preparation of g-C3N4 /TiO2 composite coating, the coating preparation of different calcination temperature and different calcining time, different diluents of g-C3N4/TiO2 composite coating and the related test; Using electrochemical workstation, scanning electron microscope, XRD and contact Angle test means such as the composite coating were characterized, and evaluate its structure and corrosion resistance; By analyzing different reaction conditions on the product structure and corrosion resistance, the influence of coating on the best structure and corrosion resistance of the optimal conditions。 Research shows that: 350 degrees, 2。5 hours calcination conditions, corrosion rate of the highest sample。
