采用合金元素钒、钨和钇对低压电器触头用铜基合金进行改性,研究了其耐腐蚀性能和力学性能。结果表明,与未添加合金元素的纯铜相比,复合添加合金元素钒、钨和钇可使合金的腐蚀电位正移0.028 V,冲击吸收功增加28J,抗拉强度达到223 MPa。 The vanadium, tungsten and yttrium alloy elements were used to modify low-voltage electrical contact copper-based alloys, and their corrosion resistance and mechanical properties were studied. The results show that the addition of alloying elements vanadium, tungsten and yttrium can make the corrosion potential shift 0.028 V, the impact absorption power increase 28J and the tensile strength to 223 MPa, compared with pure copper without alloying elements.
