采用溶胶-凝胶旋涂法在304不锈钢基体上制备了ZrO2薄膜.采用电化学测试技术和往复磨损试验装置,研究了薄膜在不同NaC1溶液中的电化学腐蚀和摩擦腐蚀性能.结果 表明,涂层试样的耐蚀性和摩擦学性能均优于裸露基体.在NaCl溶液中,提高溶液温度或溶液浓度均降低了ZrO2薄膜的保护效果;基于溶液温度因素的实验研究表明,涂层试样表面出现严重的点蚀和明显的开裂;基于溶液浓度因素的研究表明,试样表面存在点蚀.对于涂层试样的摩擦磨损,随着NaCl浓度从2%增加到6.5%,磨损更加明显,腐蚀磨损加剧.“,”ZrO2 films were deposited on 304 stainless-steel substrates by a sol-gel spin coating method.Electrochemical testing technology and a to-and-fro wear test apparatus were used to study the electrochemical corrosion and tribocorrosion properties of the films in different NaC1 solutions.According to the results,the coated specimens are better than the bare matrix in resistance to corrosion and tribocorrosion.In the NaCl solutions,increasing either the solution temperature or concentration decreases the protective effects of the ZrO2 films;study of the solution temperature factor show that serious pitting corrosion and obvious cracking occur on the surface of the coated specimens;study of the solution concentration factor show pitting corrosion on the sample surfaces.Regarding the tribocorrosion of the coated specimens,as the NaCl concentration increases from 2% to 6.5%,the abrasive wear is more obvious,and the corrosive wear is aggravated.
