Abstract
In order to improve the hardness and wear resistance on condition that the self-lubricating property is ensured, Cu-Sn coatings were prepared and strengthened by combining sol-gel method and composite electroplating technology. TiO 2 sol was added to the Cu-Sn electroplating bath to obtain nano-particles reinforced Cu-Sn-TiO 2 composite coatings. The microstructure, composition, microhardness and tribological properties were analyzed. The results show that the introduction of the TiO 2 sol in the plating solution changes the composition and structure of the composite coatings. The co-deposited TiO 2 is uniformly distributed in the Cu-Sn matrix and greatly improves the microhardness and tribological properties of the Cu-Sn coating.
