. However, the seawater of Xiamen inhibits the pitting corrosion of copper alloys. No pitting corrosion is observed on copper alloy plates tested there. The copper alloys suffer from more serious pitting corrosion in the tide zone than that in the immersion zone at Qingdao after long time exposure. Key words: copper alloy; seawater exposure; pitting corrosion CLC number: TG146 Document code: A 1......
