变质高铬铸铁组织与性能的研究

Study on the Structure and Properties of a ModifiedHigh-chromium Cast Iron

采用含K、Na、Mg、Ce的盐类和合金对高铬铸铁进行喷射变质处理.结果表明,上述元素对高铬铸铁的变质程度不同,其中钾盐的变质效果最佳.分析了各变质元素对高铬铸铁组织和性能的影响.

In injected modified treatment for a high-chromium cast iron was conducted using some salts and alloys containing K、Na、Mg or Ce elements. The experimental results showed that the different elements as mentioned above had varying modifying effect,of which the kalium was the best. The influence of each modifying element on the structure and properties of a high-chromium cast iron was analysed in this paper.
