采用粉末冶金技术制备了Mo-WC-Co合金

利用金相显微镜、XRD、SEM和EDS等手段分析了Al

添加量对合金组织的影响

并研究Al

含量对合金硬度及耐磨性的影响。研究表明

Mo-WC-Co合金的晶粒度和孔隙率随着Al

含量的增加逐渐减小;当Al

含量为0.2%时合金烧结致密度最高;Al

含量超过0.2%时合金的硬度趋于平稳但耐磨性下降。

Mo-WC-Co alloy was prepared by powder melullurgy method.Effects of Al

content on microstructure

hardness and wear-resistance of the alloy were investigated by OM

XRD

SEM and EDS.The results reveal that grain size and porosities of the Mo-WC-Co alloy are reduced with increasing in Al

content.The relative density of the alloy with 0.2% Al

content reaches the maximum value.With Al

content more than 0.2%

hardness of the alloy keeps stable while the wear-resistance is declined.
