摘要 采用电弧熔炼、铜模吸铸法制备直径为5mm的Fe基块体非晶合金棒,利用销-盘式摩擦磨损试验机进行干摩擦磨损实验,利用扫描电子显微镜观察摩擦磨损形貌,研究了铁基块体非晶合金的摩擦磨损行为,并与GCr15轴承钢进行了对比。结果表明,铁基非晶合金具有较好的耐磨性能,30N载荷作用下,随着摩擦磨损行程的延长,铁基非晶合金体现了不同的磨损机制。铁基非晶合金与GCr15轴承钢的摩擦系数都集中在0.5~0.8之间,二者的耐磨性能相当。 The amorphous alloy rods with a diameter of 5mm of Fe41Co7Cr15Mo14C15B6Y2 were prepared by copper mold with sucking casting method.The characteristics of dry wear behavior for Fe-based bulk metallic glasses and GCr15 steel were investigated using pin-tray equipment at the ambient temperature in this paper.Worn surface morphologies of the samples were observed on a scanning electron microscope.Friction and wear characteristics of the Fe-based bulk metallic were studied and compared with GCr15 steel.Result indicated that the Fe-based bulk amorphous alloy shows well wear-resistance.With the wear distance extended,Fe-based bulk amorphous alloy shows different abrasive mechanism on the 30N load.The friction coefficient of the Fe-based bulk metallic glasses and GCr15 steel are both between 0.5 and 0.8.The two kinds of materials have the similar wear-resistance.
