摘要: 本文通过对Cr28Ni3和Cr15No3铸铁的显微组织、硬度及耐磨性的试验,结果表明950℃1050℃空冷处理后对Cr28Ni3铸铁影响较小,而使Cr15No3铸铁的硬度和耐磨性较大幅度提高。

关键词: 高铬铸铁, 耐磨性

Abstract: This paper deals the matallography and the hardness and the wear resistance analysis of Cr28Ni3 and Cr15Mo3 cast iron. Result shows little influence on Cr28Ni3 cast iron at 950℃ or 1050℃ after heat treatment air cold. But has considerably increase in the hardnees and the wear resistance on Cr15Mo3 cast iron.

Key words: 高铬铸铁, 耐磨性
