- Abstract
Diamond-like carbon (DLC) films are the most studied coating materials due to their mechanical and physical properties. Many studies have been conducted on the deposition methods and doping to improve the properties of these films. Among the deposition methods, the electrochemical deposition has advantages such as convenience and inexpensive equipment. In our previous study, we were able to produce a titanium dioxide (TiO2) doped DLC film by electrochemical method from a mixture of methanol (CH3OH) and titanium solution obtained by dissolving titanium metal in hydrogen peroxide (H2O2). In this study, TiO2 doped DLC films were deposited by electrolysis of solutions formed from a mixture of titanium isopropoxide (TTIP) and methanol. The films deposited at two different TTIP concentrations were characterized morphologically, structurally and elementally. Scanning electron micrographs were shown that the films are homogeneous and compact. No change was observed in the morphology of the films after annealing the films at 600 0C. Chemical analyses showed that titanium was in the form of TiO2 and the amount of titanium increased with increasing TTIP concentration. X-ray diffraction analysis revealed that TiO2 was amorphous in the DLC matrix and the film prepared with lower TTIP concentration had diamond content. After annealing at 600 0C, it was seen that this film was graphitized. The obtained findings showed that TiO2 doped DLC nanocomposite films can be easily deposited with the solution proposed in this study.
