摘要
本文通过试验表明,化学抛光不仅适用于一些软金属,而且还适用于特种性能的铸铁,如高铬耐磨铸铁和锰系球墨抗磨铸铁。化学抛光能清晰地显示出试样内部不同的显微组织形态。本文还阐明了化学抛光的适用范围,总结了化学抛光的优点,指出化学抛光是一种有发展前途,值得推广使用的方法。
This paper deals with the application of chemical polishing not only to mild metals, but also to cast iron having particular properties, such as the wearresistant high—chromium and the wearresisting nodular iron in manganese system. The method of chemical polishing is anailable for allowing the different internal microconstituents to appear clearly. The artical describes the wide scope of the application of it, summing up its aduantages. It has a future in development, and is worth popularizing.
