%X Crystalline diamond (CD) particles are incorporated into diamond-like carbon (DLC) films in order to prevent CD-DLC electrochemical corrosion. In this paper, the influence of the diamond particle sizes on the electrochemical corrosion resistance of CD-DLC films was investigated. The films were grown over 304 stainless steel using plasma enhanced chemical vapor deposition. CD particles with 4 nm, 250 nm, 500 nm and 2-3 mu m in diameter were incorporated into DLC during the deposition process. The investigation of CD-DLC electrochemical corrosion behavior was performed using potentiodynamic method. The results show that both protection efficiency and impedance increase with the decrease of I-D/I-G ratio. It means the increase of sp(3) bonds in DLC films reduces its electrochemical corrosion, improving the electrochemical protection efficiency and the impedance. Our results pointed out that CD-DLC films are promising corrosion protective coatings in aggressive solutions.
