The purpose of this research is to basically investigate a corrosion protection method by sacrificial anode applying to steel members in atmospheric environment. In this method, porous sintered Al-Zn plate was applied as sacrificial anode materials. In addition to this, cross-linking chemical fiber sheet was also applied as the material which has functions of continual water absorption and retention needed for sacrificial anode reaction.
In order to investigate the anticorrosive effects, electro-chemical measurements of current, potential and corrosion protection effective range of corrosion protection were carried out. Moreover, atmospheric exposure tests were conducted with specimen consisted of steel, fiber sheet and porous sintered Al-Zn plate. The measurements results showed that the effectiveness of the corrosion protection method was confirmed.
