Effect of chromium doping on high temperature tribological properties of silicon-doped diamond-like carbon films. Rodriguez, B. J., Schiller, T. L., Proprentner, D., Walker, M., Low, C. T. J., Shollock, B., Sun, H., & Navabpour, P. TRIBOLOGY INTERNATIONAL, December, 2020. Teer Coatings Ltddoi abstract bibtex Amorphous carbon films were deposited by means of closed-field unbalanced magnetron sputtering (CFUBMS). The silicon content was fixed at 1.3 at. %, while the chromium content was increased by modification of the current applied to the chromium magnetrons, with two doping levels, 0.3 and 2.7 at. %. Both, hardness and thermal stability were found to decrease as result of increasing chromium. Ball-on-disk tests revealed friction coefficients of 0.06 at room temperature with similar specific wear rate in all films (similar to 4 x 10(-13) m(3) N-1 m(-1)). Increasing annealing temperatures were found to reduce the coefficient of friction compared to room temperature values, while increasing the specific wear rate for all films.
