马氏体耐磨球墨铸铁的研究

A Study of Martensitic Wear-Resistant Nodular Graphite Cast Iron

研究了淬火介质、淬火及回火工艺对马氏体耐磨球墨铸铁组织和性能的影响。结果表明,这种铸铁可应用于断面较小的耐磨件。

In this paper the effects of quenching medium, quenching and tempering temperature on the structure and properties of martensitic wear-resistant nodnlar graphite cast iron were studied. The results show that the ductile iron can be used for small-sizd wear resistant parts.
