铝合金表面的缓蚀作用研究
Study of corrosion inhibition performance on aluminum alloy surface
摘要
Abstract
Aluminum alloy surface after treating with aqueous solution under different pH was observed by means of scanning electron microscope (SEM). The SEM image showed that aluminum alloy surface was significantly different under acid or alkaline condition because of different corrosion mechanism. The corrosion inhibition performance of five surfactants and two commercialized corrosion inhibiting agents were studied. Results showed that the corrosion inhibition effect of C12-14APG,cocofatty acid diethanol amide (6501) and LAS on aluminum alloy surface is excellent at pH -2,while under pH =9,only C12-14APG and 6501 show satisfactory corrosion inhibition effect. Among all the five kinds of surfactants under testing, C12-14 APG shows the best corrosion inhibition performance. The optimum concentration for two commercialized corrosion inhibitors differs with pH condition as well.关键词
