研究了具有谐波组织的316L不锈钢在3.5%NaCl和Hanks溶液中的腐蚀行为，并与烧结非谐波和常规（锻造）316L不锈钢进行了比较。采用线性极化法、动态极化法和电化学阻抗谱法进行了研究。谐波、常规和非谐波316 L不锈钢在两种溶液中显示出相似的耐腐蚀性。然而，谐波钢表现出更好的钝化行为相比，锻造和烧结的非谐波钢。均匀分布的细晶粒和较高的孪晶界分数归因于其钝化行为的改善。
Corrosion behavior of a 316L stainless steel with harmonic microstructure was studied and compared with a sintered non-harmonic and a conventional (wrought) 316L stainless steel in 3.5% NaCl and Hanks’ solution. The study was performed using linear polarization, dynamic polarization and electrochemical impedance spectroscopy. The harmonic, conventional and non-harmonic 316L stainless steels showed similar corrosion resistance in both the solutions. However, the harmonic steel showed better passivation behavior as compared to that of the wrought and sintered non-harmonic steel. Harmonically distributed fine grains and higher twin boundary fraction were attributed to the improvement in its passivation behavior.
