摘要
采用失重法、微观形貌观察法和电化学法研究了35CrMo钢在胍胶溶液、含砂水溶液和含砂胍胶溶液中的冲刷腐蚀行为和机理。结果显示:溶液的侵蚀性由高到低排序为含砂胍胶溶液、含砂水溶液和胍胶溶液;在含砂水中加入胍胶可明显抑制冲刷腐蚀;相比于胍胶溶液,35CrMo钢在含砂胍胶溶液中腐蚀电流密度的增大说明砂粒的存在能显著提高由力学作用引起的腐蚀增量。
The erosion corrosion behavior and mechanism of 35CrMo steel in guanidine gum solution,sand water solution and sand guanidine gum solution were investigated by weight-loss method,microstructure observation,and the electrochemical method.The results showed that the descending order of solution erodibility was as following:sand guanidine gum solution,sand water solution and guanidine gum solution.Guanidine gum added into the sand water solution could reduce erosion corrosion.The corrosion current density of 35CrMo steel was higher in the sand guanidine gum solution than in the guanidine gum solution,indicating that the presence of sand can significantly raise the corrosion increment caused by mechanical action.
