摘要
在Ｐｄ － Ａｇ － Ｃｕ 合金中添加０－５ ～２ ｗｔ％ 的Ｐｔ， ０－５ ～５ ｗｔ％ 的Ｍｎ ， ０－５ ～１０ ｗｔ％ 的Ｎｉ， ０－０１ ～０－５ ｗｔ％ 的Ｓｍ ， 研制出２ 种用于玻璃釉电位器的电刷材料Ｐｄ － Ａｇ － Ｃｕ － Ｍｅ１ 和Ｐｄ － Ａｇ － Ｃｕ － Ｍｅ２ 合金。分析２ 种钯基合金材料的物理性能， 加工硬化、时效特性和组织结构， 结果表明， 添加微量Ｓｍ 能有效改善材料的耐磨性能。与进口材料ＴＹ－ ７０ 和美国Ｊ． Ｍ． ＭＥＹ 公司的专利高强度合金Ｐａｌｌｉｎｅｙ － ７ 合金等弹性电刷合金相比， 上述钯基合金材料具有更高的强度和硬度， 可替代ＴＹ－ ７０ 和Ｐａｌｌｉｎｅｙ － ７
Adding 0 5～2 wt% of Pt,0 5～5 wt% of Mn,0 5～10 wt% of Ni,0 01～0 5 wt% of Sm to Pd-Ag-Cu alloy,both Pd-Ag-Cu-Me 1 and Pd-Ag-Cu-Me 2 alloys researched and were produced.They are suitable for the electric brush material which used in glass glaze potentiometer.The mechanical properties,work hardening and ageing behaviour of the two Pd-base alloys have been studied.The results indicated that additive of trace element Sm could improve wearability effectively.Comparing with TY-70 and the high strenth patent alloy-Palliney-7 from J.M.NEY Co.of America,the two Pd-base alloys have had super strength and hardness,and could used to replace TY-70 and Palliney-7 alloy for electric brush and elastic sliding contact materials.
