| 摘 要： | 采用超声-电沉积方式制备Ni—Al2O3复合镀层。利用X-射线衍射仪、扫描电子显微镜、硬度仪以及摩擦磨损实验仪对复合镀层的组织结构、宏观残余应力、表面形貌、微观硬度以及摩擦磨损性能等进行研究。实验结果表明：适当的超声波作用使复合镀层基质金属Ni的晶粒细化，复合镀层的硬度提高，但也相应地增加了镀层的宏观残余应力；超声波-电沉积复合镀层的表面致密平整，镀层中粒子团聚现象减少，粒子分布更加均匀；超声-电沉积复合镀层的耐磨性明显优于单独电沉积复合镀层。

| Abstract: | Ni-Al2O3 composite coatings were prepared by ultrasonic-electrodeposition.The micro-structure,macro-residual stress,surface morphology,micro-hardness and wear resistant were investigated by means of X-ray diffraction(XRD),Scanning electron microscopy(SEM),micro-hardness tester and wear machine.The results show that with proper ultrasonic effect,the grain size of metals becomes smaller,the micro-hardness and macro-residual stress of ultrasonic-electrodeposited composite coatings are both higher than that of ... |
