摘要
利用动电位扫描法和化学浸泡法研究了 316L不锈钢在两种无铬钝化工艺条件下所形成的钝化膜的耐点蚀性能。结果表明 。
The passive film was formed by the techniques of chromium free passivation developed by the authors. The pitting corrosion resistance of passive film on stainless steel 316L was studied with the potentiodynamic method and chemical immersion method. The results showed that the pitting potential increased obviously after a chromium free reagent Wb being added into the passivation solution of 35% HNO 3.
