Ni-P/GO coating on the surface of TA2 titanium can be obtained by electroless plating, followed by an analysis of the surface morphology and composition of the coating by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS), with the coating corrosion resistance to be verified by 0.5 mol/L H2SO4 and HF solution with a volume fraction of 2×10-6, and with the hydrophobicity of the coating to be tested by Droplet Angle tester system. The results show that Ni-P/GO coating is characterized with an excellent corrosion resistance ability, which helps to shield the corrosion of Ti matrix by corrosive solution; meanwhile, the corrosion potential of the coating increases from -0.45 V to -0.11 V, with the corrosion current density value being 13.8 μA/cm2, and the wetting angle of the coating after durability test being 116.849°.
