Abstract

In authorsʼ previous research, an anticorrosive method with sacrificial anode for steel members in atmospheric environment was proposed. In this method, porous sintered Al-Zn plate was applied as sacrificial anode materials. In addition to this, chemical fiber sheet was applied as the material which has functions of continual water absorption and retention needed for sacrificial anode reaction.<br>The object of this research is to clarify the influences of mixing and porosity ratios of the sintered plate and property of the fiber sheet on the anticorrosive effects and to investigate applicability of the anticorrosive method in various atmospheric environments. Electro-chemical tests using the sintered plate and material property tests using the fiber sheet were carried out. Moreover, atmospheric exposure tests were also conducted on the model specimens composed of the steel plate, the fiber sheet and the sintered plate. The results showed that the anticorrosive method seems to be applicable in atmospheric environments by controlling the anticorrosive effect and consumption of anode materials by putting various kinds of the sintered plate and the fiber sheet together.
