    Abstract:

    In order to improve the hardness and wear resistance, ensure the self-lubricating property, Cu-Sn coatings were prepared and strengthened by combining sol-gel method and composite electroplating technology. In the paper, TiO2 Sol was added to the Cu-Sn electroplating bath to obtain nano-particles enhanced Cu-Sn-TiO2 composite coatings. The micro-structure, microhardness and tribological properties were analyzed in detail. The results show that the introduction of the TiO2 Sol in the plating solution leads to change the composition and structure of the composite coatings. The co-deposited TiO2 is uniformly distributed in the Cu-Sn matrix and contributes greatly to improve the microhardness and tribological properties of the Cu-Sn alloy coating.
