The　galvanic　corrosion　behavior　of　conductive　silicon　rubber　(CSR)　couples　with　different　alloys　(aluminum　alloy,　nickel-plated　aluminum　alloy)　were　investigated　in　3.5%　sodium　chloride　solutions　in　sealed　container　by　means　of　electrochemical　measurement,　weight-loss　determination,　and　surface　characterization.　It　was　found　that　weight-loss　method　couldn＇t　be　the　only　way　to　evaluate　the　corrosion　behavior　of　the　substrates　with　plated　layer.　The　corrosion　mode　of　aluminum　alloy　was　selective　and　oxygen　absorption　corrosion,　which　was　carried　out　along　the　{(1)　over　bar(0)　over　bar(0)　over　bar}　planes.　The　nickel　layer　of　nickel-plated　aluminum　alloy　could　exert　a　protective　effect　at　the　beginning　of　corrosion.
