摘要

金属的腐蚀控制在技术上、经济上、环境上和美学上都很重要。最好的选择是使用抑制剂来保护金属和合金免受腐蚀。由于有机缓蚀剂本质上是有毒的，因此推广了可生物降解的、不含重金属和其他有毒化合物的绿色缓蚀剂。此外，植物产品价格低廉，可再生，易得。单宁、有机氨基酸、生物碱和植物源有机染料具有良好的缓蚀能力。植物提取物中含有许多有机化合物，具有O、P、S、n等极性原子，这些化合物被这些极性原子吸附在金属表面，形成保护膜，并服从各种吸附等温线。介绍了各种类型的绿色缓蚀剂及其对不同金属的影响。

Greener Approach towards Corrosion Inhibition

Corrosion control of metals is technically, economically, environmentally, and aesthetically important. The best option is to use inhibitors for protecting metals and alloys against corrosion. As organic corrosion inhibitors are toxic in nature, so green inhibitors which are biodegradable, without any heavy metals and other toxic compounds, are promoted. Also plant products are inexpensive, renewable, and readily available. Tannins, organic amino acids, alkaloids, and organic dyes of plant origin have good corrosion-inhibiting abilities. Plant extracts contain many organic compounds, having polar atoms such as O, P, S, and N. These are adsorbed on the metal surface by these polar atoms, and protective films are formed, and various adsorption isotherms are obeyed. Various types of green inhibitors and their effect on different metals are mentioned in the paper.

期刊介绍： Chinese Journal of Engineering Design is a reputable journal published by Zhejiang University Press Co., Ltd. It was founded in December, 1994 as the first internationally cooperative journal in the area of engineering design research. Administrated by the Ministry of Education of China, it is sponsored by both Zhejiang University and Chinese Society of Mechanical Engineering. Zhejiang University Press Co., Ltd. is fully responsible for its bimonthly domestic and oversea publication. Its page is in A4 size. This journal is devoted to reporting most up-to-date achievements of engineering design researches and therefore, to promote the communications of academic researches and their applications to industry. Achievments of great creativity and practicablity are extraordinarily desirable. Aiming at supplying designers, developers and researchers of diversified technical artifacts with valuable references, its content covers all aspects of design theory and methodology, as well as its enabling environment, for instance, creative design, concurrent design, conceptual design, intelligent design, web-based design, reverse engineering design, industrial design, design optimization, tribology, design by biological analogy, virtual reality in design, structural analysis and design, design knowledge representation, design knowledge management, design decision-making systems, etc.
