【Abstract】 The effects of the different kinds of surfactants on the hardness and wear resistance of electroless Ni P SiC plated composite coating were studied.The experimental resluts showed that the properties of the composite coating obtained from the bath solution containing both nonionic surfactant and positive ion surfactant were superior to that obtained from the solution containing one surfactant alone.The coating containing 8%P and 3%SiC was characterized as amorphous structure.The hardness of the coating could reach 900 HV.The wear resistance of the coating was 5～6 times as high as that of nickel coating.更多还原
