Study on the Simulated Cold Copper Alloy with High Tarnish REsistance
高抗变色铜基仿金合金的研究
The semi-bright Ag-RE ( silver-rare earth) composite deposits have the properties of higher hardness and wear resistance, greater adhesive strength, higher tarnish resistance, as well as lower porosity and lower contact resistance than pure silver plating layers.
这种银&稀土(Ag-RE)复合镀层比镀银层硬度高、耐磨,结合力和抗变色性能强,而且孔隙率和接触电阻都较低。
It has good corrosion and tarnish resistance in vitro. Immersing it in 0.1% Na_2S solution for 60 days, it appears little tarnish only, but still with good lustre.
本合金在0.1%Na2S溶液中浸渍60天,仅有极轻微变色,仍有较好光泽;
