Abstract

In this paper, the PANI/PDA-TiO composite coating was prepared on 316L by constant current deposition with a current density of 2.8 mA·cm, in which the TiO powders were modified by PDA (polydopamine). The open-circuit potential of the obtained PANI/PDA-TiO composite coating is about 365 mV, which is more positive than that of the bare 316L. During immersion in 1 M HSO + 2 ppm HF for 200 h, the high stable corrosion potential and the lower indicate that the composite coating has long-term corrosion resistance.

摘要

在本文中，通过恒电流沉积法，以2.8 mA·cm的电流密度在316L上制备了聚苯胺/聚多巴胺修饰的二氧化钛（PANI/PDA-TiO）复合涂层，其中二氧化钛（TiO）粉末通过聚多巴胺（PDA）进行了改性。所制备的聚苯胺/聚多巴胺修饰的二氧化钛复合涂层的开路电位约为365 mV，比裸316L更正向。在1 M硫酸 + 2 ppm氢氟酸中浸泡200小时期间，高稳定的腐蚀电位和较低的（此处原文缺失相关内容）表明该复合涂层具有长期耐腐蚀性。
