摘要：
Diamond-like carbon films (DLC) are deposited on Ti substrate by electrochemical anodic deposition at room temperature in pure methanol solution using a pulsed DC voltage at a range from 200 V to 2000 V. Raman spectroscopy analysis of the films reveals two broaden characteristic absorption peaks centred at similar to 1350 cm(-1) and 1580 cm(-1), relating to D-and G-band of typical DLC films, respectively. A broad peak centred at 1325-1330 cm(-1) is observed when an applied potential is 1200 V, which can confirm that the deposited films contained diamond structure phase. Tribological properties of the coated Ti substrates have been measured by means of a ball-on-plate wear test machine. A related growth mechanism of DLC films by the anodic deposition mode has also been discussed. (C) 2012 Elsevier B. V. All rights reserved.
