摘要
报道了滑环摩擦副电镀Pd -Ni/Rh/Au和电镀Pd -Ni/Au的汇流环试验情况 :电图象法测孔隙率 ;在 5± 1 %NaCl溶液、 35± 2℃下连续喷雾 48h进行盐雾试验 ;在SO2 7×1 0 - 4 % (V/V) ,H2 S 1× 1 0 - 4 % (V/V) ,32～ 35℃下进行 2 4h静态硫化试验。结果表明 ,汇流环整体上基本无腐蚀现象 ,即镀层基本上无孔隙 。
The test results of the slip-ring plating Pd-Ni/Rh/Au and Pd-Ni/Au in sliding pairs are reported.The porosity are determined by electrograph.The neutral salt spray experiments are carried out at 35±2℃ in 5±1% NaCl solution for a period of 48h.The static sulfuration experiments are carried out at 32～35℃ in SO 2(7×10 -4 %)and H 2S(1×10 -4 %)atmosphere for a period of 24h.The results indicated that the corrosion phenomenon in the slip-ring were not basically found,and that no porosity was found on the deposits.The slip-ring in the sliding pairs are suitable to use for corrosion-resisting demand in the environmental atmosphere.
