摘要
采用静态挂片和动电位扫描法,研究了1Cr18Ni9Ti不锈钢在碱(NaOH)/表面活性剂/水解聚丙烯酰胺(HPAM)三元复合驱介质中的腐蚀行为。结果表明:不锈钢除在NaOH溶液中未见点蚀外,在其他几种介质中均有点蚀;在HPAM溶液中1Cr18Ni9Ti不锈钢的点蚀敏感性最大,在含NaOH的介质中点蚀敏感性降低。
The corrosion behaviors of lCrl8Ni9Ti stainless steel in Alkali (NaOH)/surfactant/HPAM solutions are studied by weight loss and potential scanning methods. The results show that lCrl8Ni9Ti stainless steel occurs pitting corrosion in all studied solutions with exception of the NaOH solution. The pitting sensitivity of lCrl8Ni9Ti stainless steel in the HP AM solution is the highest, and the pitting sensitivity becomes lower in the solutions with NaOH.
