摘　　要：为解决制备Ni-B合金镀层时难以获得高非晶化结构的问题,采用控制变量法探索镀液成分对Ni-B合金镀层非晶化过程的影响规律,电沉积法制备出高B非晶态Ni-B复合镀层。采用X射线衍射技术(XRD)表征沉积层的相结构,利用场发射扫描电镜(FESEM)和能谱分析(EDS)考察沉积层的微观形貌和元素分布组成。结果表明:通过控制溶液组分,沉积层发生从晶态到非晶态的转变。所得沉积层非晶化程度较高,此体系可电沉积获得表面完整、紧密细致、几乎没有金属晶体衍射峰的非晶态Ni-B合金沉积层,沉积层中B含量可提高至10.21%(质量分数)。In order to solve the problem that it is difficult to prepare highly amorphous Ni-B alloy coating,the control variable method was used to explore the influence law of bath composition on the amorphous process of Ni-B alloy coating,and the electrodeposition method was used to prepare high-B amorphous Ni-B composite coating.X-ray diffraction(XRD)was used to characterize the phase structure of the sedimentary layer,and field emission scanning electron microscopy(FESEM)and energy spectrum analysis(EDS)were used to investigate the microscopic morphology and element distribution composition of the sedimentary layer.The results show that the sedimentary layer can be changed from crystalline state to amorphous state by controlling the composition of solution.The resulting sediments are highly amorphous.This system can be electrodeposited to obtain amorphous Ni-B alloy sediments with a complete,close and meticulous surface,and almost no metal crystal diffraction peak.The content of B in the sediments can be increased to 10.21%(mass fraction).
