    摘要:

    為了進(jìn)一步提高Cu-Sn鍍層的硬度和耐磨性,在保持鍍層自潤滑性能的基礎(chǔ)上,采用納米溶膠技術(shù)與復(fù)合電鍍技術(shù)相結(jié)合的方法,將納米TiO2溶膠加入到電解液,制備獲得TiO2納米粒子強(qiáng)化的Cu-Sn-TiO2復(fù)合鍍層。通過對(duì)顯微硬度、摩擦學(xué)性能和微觀組織結(jié)構(gòu)的分析表明,適量納米TiO2溶膠的加入,細(xì)化了Cu-Sn鍍層組織,提高了鍍層的致密性,硬度和耐磨性均較Cu-Sn鍍層顯著提高。

    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.
