A film of Ni-P-Carbon-nanotube composite material is deposited on the surface of the metal substances by electro-brush plating. In this process, the composition of the Ni-P-Carbon-nanotube composite plating solution, the pretreatment on the carbon-nanotube and the effects on quality by the different brush plating technology conditions are investigated. The results shows that carbon-nanotube particles can be distributed uniformly in the coating by oxidizing, sensitizing and activating while the temperature of the plating solution should be controlled at 55°C, and PH value, 1.5~2.5. After the carbon-nanotube is added, the coating defects, such as the crack, the desquamation and the low bond strength, can be prevent effectively.
