摘　　要：通过真空电弧熔炼制备了一系列钛基非晶复合材料和钛基非晶合金,研究了合金中铍元素的含量对整体合金摩擦行为的影响。随着合金中铍元素的减少,非晶复合材料中的枝晶体积分数逐渐增加,整体合金的摩擦系数降低,但是合金的磨损率升高。所有材料的磨损表面都展现出了磨粒磨损的磨损机制,并且磨屑的尺寸随着枝晶体积分数的升高而逐渐降低。A series of Ti-based bulk metallic glass composites(BMGCs)and a Ti-based bulk metallic glass were prepared by arc melting,and the effect of Be contents on the wear performance was investigated.The results show that the decrease in Be content in the composites increases the volume fraction of dendrites in BMGCs;the increase in the volume fraction of dendrites reduces the coefficient of friction,but increases the wear ratio slightly.All the worn surfaces show abrasive wear,and the size of wear debris is decreased with increasing the volume fraction of dendrites.

关 键 词：非晶复合材料 摩擦行为 枝晶体积分数
