摘要：Marine biofouling is a major issue deteriorating the service performance and lifespan of marine *** development of a durable,long-term,and environment-friendly antifouling coating is therefore of significant importance but still a critical challenge in maritime ***,we developed a Cu-Ti composite antifouling coating with micron-sized alternating laminated-structure of Cu/Ti by plasma spraying of mechanically mixed Cu/Ti *** coating was designed to enable controlled release of Cu ions through galvanic dissolution of Cu laminates from the Cu/Ti micro-galvanic cell in aqueous *** showed that remarkable antifouling efficiency against bacterial survival and adhesion up to~100%was achieved for the Cu-Ti ***/Ti micro-galvanic cell was in-situ formed within Cu-Ti coating and responsible for its Cu ions *** successive dissolution of Cu laminates resulted in the formation of micro-channels under Ti laminates near surface,which contributed to controlled slow Cu ions release and self-polishing ***,environment-friendly antifouling capability and∼200%longer antifouling lifetime than that of the conventional organic antifouling coatings can be achieved for the Cu-Ti *** the other hand,as compared to the conventional organic antifouling coatings,the Cu-Ti composite coating presented much higher mechanical durability due to its strong adhesion strength,excellent mechanical properties,and two orders lower wear *** present laminated Cu-Ti coating exhibits combination of outstanding antifouling performance and high mechanical durability,which makes this coating very potentially candidates in marine antifouling application.

摘要：As system of a serial of technologies and engineering activities, remanufacturing aims at restoring and rebuilding waste machinery through advanced technologies and industrialized measures under the direction of the product total life cycle theory. With the development of surface engineering, nano-surface engineering has been one subject of intensive studies. In addition, nano-surface engineering has become an important means for property reforming and promoting of remanufacturing parts. Many low-dimension and nano-size or nano-structure functional coatings, which can improve materials properties evidently, are deposited by new methods. In this paper, some researches about the new achievement and remanufacturing application of the nano-stmctured coatings by different nano-surface engineering technologies in our laboratory were introduced. Especially, nano-structured DLC multilayer coatings by d.c. plasma CVD, nano-composed Al2O3/Ni, SiC/Ni and Diamond/Ni coatings by brush plating, and nano-composed Al2O3/TiO2 coating by plasma spraying were introduced in detail.
