摘要

在碳钢的酸洗工艺过程中,常需添加适量的酸洗缓蚀剂以防止钢表面造成过酸洗现象及消除酸洗过程中可能产生的氢脆问题。碳点作为一种对环境友好、廉价易得、化学稳定性好、具有潜在高缓蚀性能的“绿色”纳米材料,在腐蚀防护领域具有良好的应用前景。综述了国内外近年来碳点对于碳钢在酸性介质中在金属腐蚀防护领域的研究进展,对其缓蚀机理进行了探讨,对在腐蚀防护研究中存在的问题进行了简单阐述,并展望了碳点在防腐领域的发展趋势。

Abstract

In the pickling process of carbon steel, it is often necessary to add an appropriate amount of pickling corrosion inhibitors to prevent the steel surface from over-pickling and to eliminate the potential for hydrogen embrittlement during the process. Carbon dots (CDs), as a kind of green nano-material, are environmentally-friendly, low-cost, chemically stable and have potentially high inhibition performance, gradually showing good prospects for application in the field of corrosion protection. In this paper, the research progress of carbon dots in the field of metal corrosion protection of carbon steel in acidic media both domestically and internationally in recent years was reviewed, and their inhibition mechanism was discussed; the problems existing in the research of corrosion and protection were briefly described, and the development trend of CDs in the field of metal corrosion and protection was also prospected.
