摘　　要：为了增大非晶合金尺寸,设计了一种新型摩擦焊装置,用来连接毫米尺度的非晶合金棒料.该装置主要由主轴旋转单元,直线驱动单元以及参数控制单元三部分组成,分别实现工件的旋转、直线运动、摩擦焊接参数控制及采集.采用LABVIEW软件搭建了操作界面,实现焊接过程中主要参数的输入及监控采集.以Zr 55Cu 30Al 10Ni5非晶棒料为焊接对象,在不同焊接参数下进行了摩擦焊试验.结果表明,较高的转速能更快的让摩擦界面较短时间内完全进入过冷液相区,成功实现工件连接.新型摩擦焊装置能够实现非晶合金棒料的连接,达到设计要求.To increase the dimension of bulk metallic glass,a new friction welding set-up was constructed for joining the bulk metallic glass rods with millimeter dimension.This friction welding setup includes spindle rotation unit,linear driving unit and parameters control unit.They were used to carry out the rotary motion,linear motion,parameters control and collection during friction welding,respectively.The LABVIEW software was used to design the operation interface for inputting and monitoring ＆ collecting experimental data.With the different welding parameters,Zr55Cu30Al10Ni5 bulk metallic glass rods were welded using the new friction welding set-up.The results indicate that the high rotate speed makes the temperature in whole interfaces reach supercooled liquid region within a very short time,also it facilitates workpieces to be weld successfully.The new friction welding set-up can be used to join the bulk metallic glass rods and the design meets the requirement.
