中文摘要:
      目的 设计一种新型牺牲阳极, 满足海洋工程钢结构阴极保护不同时期保护电流需求, 节约牺牲阳极用量。方法 通过改变常规阳极面积与质量比, 分别设计面积相同和质量相同的新型阳极和常规阳极, 并进行静态海水阴极保护对比试验。结果 面积与常规阳极相同的新型阳极, 在节约质量近50%的基础上, 实现了与常规阳极相近的发生电流; 质量与常规阳极相同的新型阳极, 表面积增加近70%, 实现了初期发生电流增加18%, 试验阶段发生电流增加14%, 被保护钢试样的快速极化。结论 通过增加常规阳极面积与质量比, 降低接水电阻, 增加发生电流的设计思路是可行的。
英文摘要:
      Objective A new type of sacrificial anode was designed to meet the protection current demand at different times of marine engineering steel structures and achieve the purpose of saving the amount of sacrificial anode. Methods By changing the area to weight ratios of the conventional anode, the same area and quality of conventional anode and new type anode were designed, respectively, and the comparative tests of cathodic protection in static seawater were carried out. Results One new type of anode, saving nearly 50% by mass, realized the similar current outputs with the same area of conventional anode. Another new type of anode, owning similar quality with the conventional anode, was increased nearly 70% of the surface area, and achieved the current outputs increasing 18% at the initial stage and 14% throughout the test, and the rapid polarization of the protected specimens. Conclusion By increasing the area to weight ratios of conventional anode, it is feasible to reduce the anode-to-electrolyte resistance, and then increase the current outputs.
