摘要
采用超声辅助脉冲电沉积方法在45#钢表面制备NI-TiN复合镀层。。利用X射线衍射仪(XRD)对复合镀层的物相组成进行检测分析,并利用原子力显微镜(AFM)、透射电镜(TEM)对Ni-TiN复合镀层的立体表面形貌及晶粒的分布进行观察分析。结果表明:当超声波功率为300 W时,所制备的Ni-TiN纳米复合镀层衍射峰强度最高,且含有Ni、TiN两相,Ni晶粒得到显著细化,TiN纳米颗粒分布较为均匀,无显著团聚现象发生。
Ni-TiN composite coatings were prepared by ultrasound-assisted electrodepositing method on 45# streel. The composite coating was detected by XRD diffraction. And the 3-dimensional surface topography of the composite coatings were observed and analyzed by using atomic force microscopy（ AFM） and transmission electron microscopy（ TEM）. The result indicate that the diffraction peak intensity of Ni-TiN nano composite coating is the highest,and the Ni and TiN phases are significantly refined when the ultrasonic power is 300 W. The distribution of TiN nanoparticles is uniform,and there is no significant aggregation in the coating.
