- 2009-2010年度科学研究費補助金(若手研究(B))研究成果報告書 課題番号：21760347 研究代表者：山口明伸 (鹿児島大学理工学研究科（工学系）准教授)本研究は、犠牲陽極方式の電気防食工法を、腐食因子の浸透を抑制するための塗装としての役割に防食効果を加えた「新しい高機能塗装」ととらえ、その適用性について検討したものである。その結果、犠牲陽極材として用いる溶射金属種類とその表面処理方法、環境条件、対象構造物の劣化程度等が、犠牲陽極方式の電気防食効果に与える影響を明らかにするとともに、犠牲陽極方式電気防食工法をコンクリート構造物の維持管理に効果的に活用する手法を提案した。A galvanic anode system is one of the ways of cathodic protection used to protect metal from corrosion using galvanic or sacrificial anodes. However, it is so difficult to control the corrosion reaction of sacrificial anode metal in the system that only seldom attempt has been tried for actual concrete structures. In order to apply this system more effectively in the fields of maintenance of concrete structures, electrochemical properties of sacrificial anode metals in several environments must be considered in detail. In this study, considering the system as a new coating system with a function of Cathodic protection, the influence of anode types, environmental conditions and deterioration levels of the concrete structure upon the effect of the system were clarified by experimental examinations.
