Abstract

In this study, we proposed the sacrificial anode cathodic protection method as a countermeasure to reduce the corrosion of the steel sculptures under outdoor conditions and proved the anticorrosive effect experimentally. To affix the Mg sacrificial anode and the steel plate specimen, an adhesive bonding strength test was conducted with three types of conductive adhesives. Hence, the suitability of the conductive epoxy adhesive was confirmed, and a C-clamp experiment was conducted to supplement the connection. In addition, by applying a sacrificial anode suitable for the soil where the artwork is installed, the field applicability was reviewed through an artificial determination of resistance to cyclic corrosion conditions test(salt fog/dry/humid) to prove the suitability of the cathodic protection method by sacrificial anode. Hence, corrosion monitoring is in progress by test-laying steel plate specimens in an outdoor sculpture park to identify natural deterioration. In the future, based on the results of the outdoor exposure test, we plan to determine the proper method of bonding the sacrificial anode and the steel sculpture, and the replacement period of the sacrificial anode.

室外雕塑腐蚀阴极防护的适用性研究

在本研究中，我们提出了牺牲阳极阴极保护方法作为减少室外条件下钢雕塑腐蚀的对策，并通过实验验证了其防腐效果。为了将Mg牺牲阳极与钢板试样进行粘接，采用3种导电胶粘剂进行了粘接强度试验。因此，确认导电环氧胶粘剂的适用性，并进行C-clamp实验来补充连接。此外，通过应用适合艺术品安装土壤的牺牲阳极，通过人工测定耐循环腐蚀条件试验(盐雾/干燥/潮湿)来审查现场适用性，以证明牺牲阳极阴极保护方法的适用性。因此，腐蚀监测正在进行中，通过在室外雕塑公园试验铺设钢板试件来识别自然劣化。在未来，我们计划根据室外暴露试验的结果，确定牺牲阳极与钢雕塑的合适粘结方法，以及牺牲阳极的更换周期。
