【摘要】 通过测定失重量和摩擦力矩的波动情况,得出在不同工艺参数条件下试样的抗磨损性和摩擦系数的变化规律。实验结果表明:搅拌摩擦焊接头的摩擦磨损性能明显优于母材,当正压力从50N增加到100N时,母材的失重量增加近6倍,母材的失重量在同等加载情况下是焊缝的10￣20倍。实验还表明搅拌摩擦焊接头的摩擦力矩较小并且波动平缓。更多还原

【Abstract】 Variation rule of wear-resistance property and coefficient of friction were investigated by testing for wear mass loss and moment of friction under different parameter condition. The result shows that friction stir weld is much better wear-resistance than base material. The abrasion loss of base material is increased by six times when position pressure is increased from 50N to 100N and the abrasion loss is as 10~20 times as that of friction stir welds. The number of friction-moment of friction stir welds is low and stable.更多还原
