| 摘 要： | 用失重法研究了冷轧钢在不同浓度十六烷基三甲基溴化铵的盐酸、草酸、硝酸介质中的腐蚀行为,所得结果表明在盐酸介质中十六烷基三甲基溴化铵是冷轧钢优异的缓蚀剂,其在冷轧钢表面的吸附符合Langmuir模型,实验数据亦表明草酸溶液中十六烷基三甲基溴化铵对冷轧钢的腐蚀影响甚微,并且发现十六烷基三甲基溴化铵在硝酸介质中是冷轧钢腐蚀的增蚀剂.

| Abstract: | The corrosion behavior of cold rolled steel in hydrochloric acid,oxalic acid and nitric acid media in the presence of various concentrations of hexadecyltrimethylammonium bromide was studied using weight loss measurements.Results obtained revealed that hexadecyltrimethylammonium bromide is a very good inhibitor for cold rolled steel in hydrochloric acid,and the adsorption of the inhibitor on the cold rolled steel surface followed the Langmuir adsorption isotherm.Experimental data also indicated that the effect of hexadecyltrimethylammonium bromide on cold rolled steel corrosion is slight in oxalic acid solutions,and it was found that hexadecyltrimethylammonium bromide as an accelerator of cold rolled steel corrosion in nitric acid media. |

| Keywords: | cold rolled steel hexadecyltrimethylammonium bromide hydrochloric acid oxalic acid nitric acid inhibitive action corrosion behavior |
