Abstract

Abstract : 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.
