Abstract:The principal surface modification technologies concerning copper and copper alloys, including ionic liquid plating, plasma spraying, laser cladding, laser alloying, laser surface hardening and surface remelting, were reviewed. Through proper surface modification, the relevant performances, the corrosion and wear resistance of the copper and copper alloys will be improved, which broadens the applications of copper and copper alloy. The superiorities of each modification technology were discussed as well as its drawbacks, focusing on the technical challenge from the high thermal conductivities of copper and copper alloys. And the trends of the modification technologies were briefly prospected in the end.
Key words: copper; copper alloys; surface treatment; electroplating; coating; laser processing
