灰铸铁和球墨铸铁的失效形式以及常用的强化手段

Failure Forms of Gray Cast Iron and Nodular Cast Iron and Their Strengthening Methods

灰铸铁和球墨铸铁因其优越的性能、低廉的价格在工业中得到广泛的应用,但是因为石墨软基相的存在,耐磨性耐蚀性较差,因此需要表面处理去除石墨相,提高其性能。

Gray iron and nodular cast iron are widely used in industry because of their superior performance and low cost,but the existence of soft graphite phase?leads to?poor wear resistance corrosion resistance,so surface treatment is needed to remove the graphite phase to improve gray iron and ductile iron performance.
