摘　　要：研究了载荷对Zr_(55)Cu_(30)Ni_5Al_(10)大块非晶合金往复直线滑动摩擦磨损行为的影响。研究表明,随着载荷增加,平均摩擦系数下降,但磨痕宽度增大。磨痕呈平滑直线型犁沟,载荷越大,磨损越严重;载荷较小时,非晶合金呈典型的轻微咬合或咬焊、连续磨损机理,随载荷增大,咬合或咬焊及粘着磨损作用机理增强,呈连续磨损、咬合或咬焊及粘着磨损共同作用机理。The effects of load on friction and wear behavior of a Zr_（55）Cu_（30）Ni_5Al_（10） bulk metallic glass in linear reciprocating sliding were investigated.The results show that,with the increase of load,the average frictional coefficient descends,and the width of the grinding trace increases.The grinding traces exhibit smooth linear furrows.The larger the load is,the more serious the wear is.Under small loads,the wear mechanism inclines to a combined result of slight bite or bite welding and continuous wear.With the increase of load,the wear mechanism gradually changes into a combined effect of continuous wear,occlusion or bite welding,adhesive wear and abrasive wear.
