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。 Aiming at the problem that the traditional sacrificial anode increases the hydrogen embrittlement susceptibility of high strength steel due to overpotential, Ga is used as the main activation element, Zn and Si are added to improve the dissolution performance of the anode, and the low sacrificing potential Al alloy with good electrochemical performance is developed Anode material, and verified its protective effect on high strength steel, evaluated its impact on the sensitivity of high strength steel to hydrogen embrittlement.
