摘要

为了提高铜合金表面的耐蚀性，研究了La2O3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La2O3纳米粒子与硅烷对铜合金表面性能的影响。结果表明：La2O3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La2O3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。

Abstract

In order to improve the corrosion resistance of the copper alloy surface, the synergistic effect of La2O3 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 La2O3 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 La2O3 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, La2O3 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.

Key words： copper alloy; La₂O₃ nanoparticles; silane; synergistic effect; corrosion resistance
