摘要
对亚硝酸钠钝化的各种工艺条件进行比较,并用酸性CuSO4滴定法检测钝化膜质量,筛选出能形成优良钝化膜的亚硝酸钠钝化的最佳工艺条件。
All passivation techniques with sodium nitrite were compared, the quality of passivation film was examed with the acidic CuSO4 dropping method. The NaNO2 passivation technique was the best choice, which could form good passivation film.
