, implying poor adhesion of CNTs to Ni matrix. With increasing the CNT content in the coating, the corrosion resistance of the Ni-CNT composite coating becomes inferior due to the porous microstructure. Key words: composite coating; carbon nanotube; electrodeposition 1 Introduction Electrodeposition of composite coatings has been widely investigated for better wear resistance and dispersion......
