摘要/Abstract

摘要： 在化学镀镍磷溶液中添加金纳米粒子，在基体钢铁上沉积得到镍-磷/金纳米粒子复合镀层. 金纳米粒子在镀液中的浓度为1.0?μmol•L-1. 用扫描电子显微镜，能谱仪，示差扫描热量分析仪，X射线衍射仪，显微硬度计等仪器对镀层性能进行了分析. 通过EDS分析表明，NiP镀层中P的质量分数为9.72%，而NiP/Au镀层中P质量分数为9.29%，金的质量分数为0.93%. 与镍-磷合金镀层相比，纳米复合镀层具有较高的硬度，并且镀层组织致密，孔隙率小，对基体具有更好的保护作用.

Abstract: The nano composite coating of NiP/Au was obtained by adding gold nanoparticles into the NiP electroless plating solutions. The concentration of gold nanoparticles in electroless plating solution is 1.0?μmol•L-1. The coating properties were analyzed by scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), differential scanning calorimeter (DSC), Xray diffraction (XRD) and microhardness tester. The mass concentration of P in NiP electroless coating is 9.72%, while that in the composite coating of NiP/Au is 9.29% and that of Au in the composite coating is 0.93%. The hardness of the composite coating is bigger than that of NiP alloy coating. The composite coating of NiP/Au has good protection on the substrate because of its compact structure and less holes.
