一、前言铝基合金阳极近年来得了迅速发展,在海洋环境中有取代镁基和锌基阳极之势。关于铝合金阳极在土壤条件下的应用,我国的腐蚀工作者作了一些积极的工作:制定了铝阳极在土壤中应用的技术标准(草案);评述了铝基牺牲阳极填包料配方;有二十多年应用铝阳极的经验和教训。本工作旨在研究碱性填包料的基本成分及一些添加剂对铝阳极性能影响,并探索应用酸性填包料的可能性。二、实验步骤
I. Introduction Aluminum-based alloy anode has gained rapid development in recent years and has the potential to replace magnesium-based and zinc-based anodes in the marine environment. As for the application of aluminum alloy anodes under soil conditions, our country’s corrosion workers made some positive work: drafted the technical standard (draft) for the application of aluminum anodes in soil; reviewed the aluminum-based sacrificial anode packing materials formula More than 20 years of experience and lessons learned using aluminum anodes. This work aims to study the basic composition of alkaline filler and some additives on the performance of aluminum anode, and explore the possibility of using acidic packing material. Second, the experimental steps
