【Abstract】 The galvanic corrosion of graphite epoxy composite materials(GECM) coupled with steel 30CrMnSiA, LF2 aluminum alloy and TC4 titanium alloy had been studied. Electrochemical potential tests were performed for GECM and alloys in aqueous 3.5% NaCl solutions. Atmospheric corrosion was performed in 3 typical environments as Beijing, Tuandao (of Qingdao) and Wanning (of Hainan) for 1, 3, and 5 years. Galvanic corrosion of GCEM/ 30CrMnSiA couples was more serious in Wanning site. Some galvanic corrosion control methods were evaluated under different atmospheric corrosive conditions.更多还原
