Abstract:Since the strategic goal of “Strong Maritime Nation” was put forward, the marine and ship engineering technology has been developed rapidly, which puts forward higher and higher requirements for the corrosion resistance of materials. Copper alloy system has been widely used in marine and marine engineering, petrochemical industry and other fields because of its excellent corrosion resistance to seawater. Based on the current research on the corrosion behavior of copper alloys in marine environment at home and abroad, this paper summarized the corrosion behavior and related research of Ni-containing corrosion resistant copper alloys represented by Ni-Al bronze and white copper in Marine environment, combined with the influence of rare earth on the corrosion resistance of copper alloys, put forward the methods and prospects of improving the corrosion resistance of copper alloys.
