镁合金牺牲阳极是埋地管道阴极保护的主要材料。传统的镁阳极是材彤截面棒状形,从成分到规格都已标准化,但由于牺牲阳极的驱动电位有限,使得棒状阳极应用受到限制。为扩大牺牲阳极应用领域、完善应用技术,管道设计院和郑州轻金属研究院于1991年联合开展了带状镁阳极及高电位镁阳极的研究,通过一年多的研制,电化学测试及现场考查,达到了预期目的,从测取的数据看,新型镁阳极性能已达到国外同类产品水平,填补了国内牺牲阳极品种上的空白。1992年12月22日有色总公司组织的有二十余名石油、海洋、化工及冶金等行业的腐蚀专家及大专院校腐蚀权威们参加的带状镁阳极技术鉴定会对带状镁阳极给予一致的肯定。
Magnesium alloy sacrificial anodes are the main material for cathodic protection of buried pipelines. The conventional magnesium anode is a rod-shaped rod with a cross section, which has been standardized from the composition to the specification. However, due to the limited driving potential of the sacrificial anode, the application of the rod anode is limited. In order to expand the application field of sacrificial anodes and improve the application technology, the Pipeline Design Institute and the Zhengzhou Light Metal Research Institute jointly carried out the research on ribbon magnesium anodes and high-potential magnesium anodes in 1991, and through more than one year of development, electrochemical testing and on-site inspections. , To achieve the desired purpose, from the measured data, the performance of the new magnesium anode has reached the level of similar foreign products, to fill the blank on the domestic sacrificial anode varieties. On December 22, 1992, the Ribbon Magnesium Anodes were appraised by more than 20 corrosion specialists from the oil, marine, chemical, and metallurgical industries and the corrosion authority of universities and colleges organized by the Nonferrous Metals Corporation. Consistent affirmation.
