稀土添加剂在钢铁常温发黑中的作用

Effect of Rare Earth Additive on Room Temperature Blackening of Steel

在铜盐 亚硒酸钢铁常温发黑体系中加入稀土添加剂 ,通过对发黑膜外观形貌的观察 ,SEM、XRD测试 ,研究了稀土元素对发黑膜的显微组织和耐蚀性的影响。表明稀土元素可提高发黑剂的使用质量 。

The effects of rare earth additive on the microstructure and corrosion resistance of blackening film were studied in nantokite-setenious acid blackening system of steel at room temperature through appearance observation, SEM and XRD test of blackening film. Results showed that rare earth elements took anactive part in improving the use quality of blackening agent and the performance of blackening film.
