Resumo | Amorphous hydrogenated carbon (a-C:H) films have been grown using different hydrocarbon precursors in order to find the best set of mechanical and tribological proprieties. The addition of noble gases to the hydrocarbon precursor atmosphere is expected to increase the ratio of ion to neutral radicals on the surface of the growing film without changing the H/C ratio of the gas mixture. This is in fact a powerful way to investigate the effect of ion bombardment on the structural arrangement and properties of a-C:H films. In this work, acetylene (C2H2) was be studied using argon as an inert additional gas, in order to determine the mechanical and tribological properties and microstructure of a-C:H films. The films were deposited employing an asymmetrical bipolar pulsed-DC plasma enhanced chemical vapor deposition (PECVD) system and an active screen that worked as an additional cathode. The a-C:H films were analyzed according to their microstructure, mechanical, and tribological properties as a function of the amount of argon diluted in the acetylene. The films microstructure and the hydrogen contents were probed by means of Raman spectroscopy. The internal stress was determined through measurement of the change in the substrate curvature by means of a profilometer, while nanoindentation experiments allowed to determinate the hardness and the elastic modulus of the film. The friction coefficient and wear resistance of the films were determined using a tribometer, while the adhesion of the films was evaluated via the scratch test. In order to improve the a-C:H films adhesion to steel substrates, a thin amorphous silicon interlayer was used. The results showed that the atmosphere of argon diluted in acetylene induced modifications in the properties of the a-C:H films. Hard, adherent, low-stress, and high wear resistant a-C:H films were deposited on steel substrates using a combination of a modified and asymmetrical bipolar pulsed-DC PECVD system, an active screen as additional cathode, and acetylene-argon atmospheres. The use of an amorphous silicon interlayer improved the a-C:H films deposition onto steel substrates. These results suggest that the used methodology represented a step forward for thin film growth by using lower pressure and higher plasma density than the conventional PECVD system and may represent a new and useful alternative for mechanical and tribological applications. |
