摘　　要：利用光学显微镜、模具孔径测量仪、扫描电镜分析了不同模具参数拉制的Ag-Pd键合合金线断口形貌及表面质量,研究了模具不同润滑区角度、不同定径区长度和形状以及出口区角度对线表面质量及拉断形貌的影响。结果表明:模具润滑区角度、定径区长度和形状、模具出口角度等对Ag-Pd键合合金线拉制质量有较大影响。确定的工艺参数为:模具润滑区角14°、定径区长度0.015 mm、模具出口角80°。Fracture morphology and surface quality of Ag-Pd bonding alloy wire drawn by different die parameters were analyzed by means of optical microscope, die aperture measuring instrument and scanning electron microscope. The effects of different lubrication area angle, length and shape of die bearing, outlet angle of the die on surface quality and drawing fracture morphologies of the wire were investigated. The results show that the lubrication area angle, length of die bearing, bearing shape and outlet angle of the die have a great influence on the Ag-Pd bonding alloy wire drawing quality. The determined process parameters are die lubrication area angle of 14°, the die bearing length of 0.015 mm, and die outlet angle of 80°.
