【Abstract】 Erosion-corrosion of Cu-Ni alloy pipe seriously influences the safety operation of ship and ocean engineering system. The research methods, corrosion mechanisms and the new methods for the characterization of erosion-corrosion of Cu-Ni alloys are reviewed in this paper. The influence of the composition, microstructure and sulfide inclusion of the alloy, as well as temperature,pH value, sand content, flow rate and impacting-angle of the flow media on the erosion-corrosion was analyzed. Finally,the trend of research on the erosion-corrosion of Cu-Ni alloy in sea water is prospected.更多还原
