Corrosion behavior of B30 Cu-Ni alloy and anti-corrosion coating in marine environment LI Qing-fen(李庆芬)1 , LI Chun-hui(李春辉)1 , XU Li-kun (许立坤) 2,LIU Guang-zhou(刘光洲)2 1. College of Mechanical... behavior of B30 Cu-Ni alloy in a sterile seawater and a SRB solution was investigated. The results show that the corrosion potential of specimen in the SRB solution is much lower than that in the sterile......
indicate there is local corrosion on Cu-Ni alloys in the immersion zone of Yulin marine, Zhoushan marine and Qingdao marine. The specimens in Yulin marine are corroded most seriously due to high temperature and marine-living adhesion. But the seawater of Xiamen inhibits the pitting corrosion of Cu-Ni alloys, so that no pitting corrosion is observed on Cu-Ni alloy plates tested......
