Q235-SiC_p surface wear-friction composites have been prepared by compound electroplate processing. The effects of concentration of SiCp in plating solution, current density, average pH and temperature of plating solution on microstructure and properties of the electroplated layer were investigated. The results show that the dry friction coefficient of electroplated layer is in the range of 0.55⁰.60,and its wear rate is less than 0.42×10 -7 cm³/J with the concentration of 35 g/L of SiC_p in plating solution and current density of 3.5 A/dm², which can meet the requirements of friction materials.
