摘　　要：研究了作为牺牲阳极材料的Ｚｎ－Ａｌ－Ｃｄ、Ａｌ－Ｚｎ－Ｉｎ－Ｓｉ－Ｍｎ和Ｍｇ－Ａｌ－Ｚｎ－Ｍｇ合金在海水中与Ａ３钢等异种金属偶接时，偶对阴极金属材料和阴阳极面积比Ａｃ／Ａａ不同。Abstract The effects of coupled time, area ratio A c/ A a and solution temperature on galvanic corrosion behavior of Zn Al Cd, Al Zn In Si Mn and Mg Al Zn Mn alloys coupled to A3 steel have been studied in sea water. Results show that the j g is directly proportional to the area ratio, and increases with increasing solution temperature when temperature is above 20 ℃.
