             abstract = "Various precursors of diamond-like carbon (DLC) growth have been 
                         studied in order to find the best set of mechanical and 
                         tribological proprieties. Gaseous hexane (C6H14) stands out as an 
                         option because of its high vapor pressure and the fact that it 
                         accepts dilution with other hydrocarbons or even nanoparticles, 
                         forming convenient colloidal substances. Therefore, in the present 
                         paper, hexane will be studied using argon as an inert additional 
                         gas, in order to determine the mechanical and tribological 
                         properties and microstructure of DLC films deposited via a 
                         modified and asymmetrical bipolar pulsed-DC plasma enhanced 
                         chemical vapor deposition system. The addition of argon to the 
                         hexane 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. The film's 
                         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 showed the 
                         hardness of the film. The adhesion of the films was evaluated via 
                         the scratch test. In order to overcome the low adhesion of these 
                         films on AISI 304 stainless steel surfaces, a silicon interlayer, 
                         obtained by using low-energy ion implantation and silane as a 
                         precursor gas, was used. The results show that the precursor 
                         hexane atmosphere diluted with argon induces modifications in the 
                         properties of the films when a high quantity of argon is used. The 
                         importance of the effect of ion bombardment during film growth on 
                         the properties of the films was confirmed.",
