采用化学镀方法在TiO 2和石墨颗粒上共沉积镍磷镀层。用扫描电子显微镜（SEM）分析了涂层的表面形貌。采用X射线衍射（XRD）分析了涂层的结构。Ni-P-Cg-TiO 2复合镀层的显微硬度介于Ni-P-Cg和Ni-P-TiO 2复合镀层之间。DSC热分析表明，TiO 2和Cg颗粒对Ni-P镀层的热稳定性没有影响。石墨颗粒的加入降低了Ni-P-TiO 2复合镀层的摩擦系数和腐蚀速率。
Titanium dioxide (TiO2) and graphite (Cg) particles were co-deposited with nickel–phosphorous (Ni–P) coatings through electroless deposition process. Surface morphology of the coatings was analysed by scanning electron microscope (SEM). X-ray diffraction (XRD) was used to detect the structure of the coatings. Microhardness of Ni–P–Cg–TiO2 composite coating showed a moderate hardness between Ni–P–Cg and Ni–P–TiO2 composite coating. DSC thermograms indicated that the thermostability of Ni–P coating could not be affected by TiO2 and/or Cg particles. Moreover, the friction coefficient and corrosion rate of Ni–P–TiO2 composite coating could be decreased by the addition of graphite particles.
