Abstract

Ni-Co-AlO composite coatings were prepared by pulsed electrodeposition and electrophoresis-electrodeposition on aluminum alloy. The content of AlO particles of the Ni-Co-AlO composite coating prepared by electrophoresis-electrodeposition was significantly higher than the composite coating prepared by pulsed electrodeposition. The composite coating prepared by electrophoresis-electrodeposition exhibited a better anti-wear performance than that prepared by pulsed electrodeposition. The morphology, composition and microstructure of the composite coatings were determined by means of X-ray diffractometer (XRD) and scanning electron microscopy (SEM). The hardness and friction properties of the samples were tested on the microhardness tester and the friction and wear loss tester respectively.

摘要

采用脉冲电沉积和电泳电沉积法在铝合金上制备了Ni-Co-AlO复合涂层。通过电泳电沉积制备的Ni-Co-AlO复合涂层中AlO颗粒的含量明显高于通过脉冲电沉积制备的复合涂层。与脉冲电沉积制备的复合涂层相比，电泳电沉积制备的复合涂层表现出更好的抗磨损性能。利用X射线衍射仪（XRD）和扫描电子显微镜（SEM）对复合涂层的形貌、成分和微观结构进行了测定。分别在显微硬度测试仪和摩擦磨损损失测试仪上测试了样品的硬度和摩擦性能。
