添加铬钼的磷铜钛低合金铸铁磨球材料研究

Research on Low P-Cu-Ti Cast Iron with Cr and Mo Additions as Grinding Balls Material

对比研究添加铬钼与未加铬钼的磷铜钛低合金铸铁磨球材料的CCT曲线、淬透性能和耐磨性能，结果表明，少量添加铬钼可提高淬透性能和耐磨性能。

A comparative test was made of the CCT diagrams, hardenabili-ties and wearresistances of low P-Cu-Ti cast irons as grinding balls materials with and without chromium and molybdenum additions.The result showed that a little addition of chromium and molybdenum could increase hardenability and wearresistance
