摘要:

采用氧化-浸泡-蒸发循环实验与电化学阻抗谱、XRD、SEM、腐蚀坑深度和腐蚀失重等测量方法,研究了汽车消声器环境中409不锈钢在烟尘作用下的腐蚀行为。结果表明,有/无烟尘作用条件下,试样表面形成的腐蚀产物相似,但烟尘会使试样的腐蚀电位略升高,并且腐蚀坑深度和腐蚀失重增加,这主要是因为烟尘与409不锈钢间具有一定的电偶腐蚀效应,减小了腐蚀体系的电荷转移电阻,从而加剧了409不锈钢在冷凝液中的腐蚀。

Abstract：

The influence of soot on the corrosion behavior of 409 stainless steel for automotive muffler was studied by means of oxidation-immersion-evaporation cycle test with electrochemical impedance spectroscopy, XRD, SEM as well as pitting depth-and corrosion weight loss-measurement. The results show that the corrosion products formed on the sample surfaces are similar in the condensate liquids with and without soot. However, the corrosion potential increases lightly and both the pitting depth and weight loss become higher for the steel in the presence of soot. These can be attributed mainly to the galvanic effect between deposited soot and the stainless steel, which reduces the charge transfer resistance of the corrosion system and accelerates the corrosion of 409 stainless steel in the condensate solution.

Key words： soot automotive exhaust system corrosion stainless steel
