摘　　要：为了提高铜合金表面的耐蚀性,研究了La_(2)O_(3)纳米粒子、硅烷的协同作用,通过优选试验获得了含有硅烷(PropS-SH)基础处理液配方,利用扫描电镜(SEM)及X射线衍射仪(XRD)对处理后的铜合金表面形貌及结构进行了分析;通过交流阻抗等电化学测试方法分析了La_(2)O_(3)纳米粒子与硅烷对铜合金表面性能的影响。结果表明:La_(2)O_(3)纳米粒子与硅烷的加入使铜合金试件表面形成了致密、均匀的La/硅烷复合膜,从而提高了铜合金表面的耐蚀性能,即La_(2)O_(3)纳米粒子、硅烷对铜合金的耐腐蚀行为具有协同作用,其效果优于传统BTA钝化效果。In order to improve the corrosion resistance of the copper alloy surface,the synergistic effect of La_(2)O_(3) nanoparticles and silane was studied. The formula of the basic silane treatment solution containing silane( PropS-SH) was obtained by orthogonal experiment,and the surface morphology and structure of the copper alloy after treatment were analyzed by scanning electron microscope( SEM) and X-ray diffraction( XRD). Moreover,the effects of La_(2)O_(3) nanoparticles and silane on the surface properties of copper alloys were analyzed by electrochemical testing methods such as AC impedance. Results showed that the addition of La_(2)O_(3) nanoparticles and silane enabled the formation of a dense and uniform La/silane composite film on the surface of the copper alloy specimens,which improved the corrosion resistance of the copper alloy. That is to say,La_(2)O_(3) nanoparticles and silane possessed a synergistic effect on the corrosion resistance of the copper alloy,and the effect was better than traditional BTA passivation effect.
