要約(英語): The corrosion behavior of aluminum wire used for overhead transmission line was studied in four corrosion environments: (1) sodium chloride solution, (2) sodium chloride solution with addition of alumina particles, (3) aluminum chloride solution, (4) aluminum chloride solution with addition of alumina particles. The corrosion test and polarization measurements reveal that the (2) and (4) environments with alumina particles roughened and rapidly corroded the surface of the aluminum wire. It is considered that the wet and dry environments of the overhead transmission line have changed aluminum hydroxide as corrosion products to alumina (aluminum oxide) which play polishing and gliding role to weaken the surface of the aluminum wire. It is also shown that the corrosion of the aluminum wire is categorized as an abrasive corrosion environment caused by alumina and corrosion fatigue by vibration of the wire in the sky.
