主　　题：Marine antifouling Cu-Ti coating Plasma spraying Micro-galvanic dissolution Durable Self-polishing 

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.
