Abstract The corrosion resistance of AISI 316L, AISI 904L, Sanicro 28, SAF 2205, SAF 2507 and SAF 2707 was studied in an acid mixture containing tartaric acid saturated solution, H 2 SO 4 and HCl, as a function of temperature (22–60 °C) and alloys composition. The stainless steels were examined through anodic polarization curves; an analytical method is proposed to obtain the characteristic parameters from these curves. The results indicate that Cr and Mo play the most important role on the active-passive transition of the tested alloys. AISI 904L, Sanicro 28 and SAF 2707 showed the best anodic characteristics among the examined stainless steels.

强酸混合物中不锈钢腐蚀的研究。第 1 部分：通过分析方法检查的循环动电位极化曲线

摘要 研究了 AISI 316L、AISI 904L、Sanicro 28、SAF 2205、SAF 2507 和 SAF 2707 在含有酒石酸饱和溶液、H 2 SO 4 和 HCl 的酸性混合物中作为温度 (22–60 °C) 和合金成分。通过阳极极化曲线检查不锈钢；提出了一种解析方法来从这些曲线中获得特征参数。结果表明，Cr 和 Mo 对测试合金的主动-被动转变起最重要的作用。AISI 904L、Sanicro 28 和 SAF 2707 在所检测的不锈钢中表现出最好的阳极特性。
