摘　　要：本文用中频单晶提拉炉固溶高纯铂、铜,研制出11片不同含量铂基铜合金,并对11片铂基铜合金进行XRD、SEM-EDS、维氏硬度的检测,根据检测结果表明铂基铜合金形成了单相固溶体,铂基铜合金的硬度随着铜含量增加呈线性增大,同时随着铜含量的增加合金体的耐腐蚀性变差,孔隙、砂眼增加,性能变差。In this paper,eleven flake samples of platinum-copper alloys were prepared by solid-solution high-purity platinum and copper in medium-frequency single crystal pulling furnace.XRD,SEM-EDS and Vickers hardness were tested on the eleven samples.Platinum-copper alloy forms a single-phase solid solution.The hardness of platinum-copper alloy increases linearly with the increase of copper content.At the same time,the corrosion resistance of the alloy body deteriorates with the increase of copper content,pores and sand holes increase,the performance deteriorates.
