| Abstract: |
| Copper and its alloys have become the indispensable material for key structures and components of ship industry and marine engineering because of their good corrosion resistance, electrical conductivity, thermal conductivity, mechanical properties and formability, and have extensive and important applications in propellers, seawater pipelines, pumps, valves and cooling systems, etc. However, due to the complex and demanding marine environment and the increasing intensity of use, copper alloys are facing more and more harsh service conditions, and the safety and reliability of key structures and components are under a great threat. The work aims to reviewthe classification and application of copper and its alloys commonly used in marine environment. The research progress on corrosion mechanism and affecting factors of typical copper alloys including pure copper, brass, cupronickel, and bronze issummarized emphatically. Finally, the future development of new copper alloys and their preparation and application are prospected. |
