摘　　要：针对传统牺牲阳极由于电位过负导致高强钢氢脆敏感性增加的问题,以Ga为主要活化元素,加入Zn和Si改善阳极的溶解性能,研制了具有良好电化学性能的低驱动电位铝合金牺牲阳极材料,并验证了其对高强钢的保护效果,评价了其对高强钢氢脆敏感性的影响。The hydrogen embrittlement sensitivity of high strength steel protected by traditional sacrificial anodes would increase due to high driving voltage. In order to solve this problem,the present work was focussed on developing low driving voltage sacrificial anode for high strength steels. Taking the Ga as main active elements,we designed and prepared several aluminum alloy anodes by adding Zn and Si for improving the dissolution performance. And the excellent sacrificial anode was attained and it could provide effective protection for high strength steel and wouldn＇t increase hydrogen embrittlement sensitivity.
