                         prepared by using different techniques and under different 
                         conditions have been of great concern. The main focus is to reach 
                         low total stress, high hardness, very high adherence with the 
                         substrate, and low friction coefficient, including the deposition 
                         in large area at high growth rate [1-2]. In this work, hard and 
                         adherent DLC films were deposited by using a low cost pulsed-DC 
                         discharge technique in methane atmosphere. Studies have been 
                         carried out in order to match the best set of parameters for 
                         deposition of hard and adherent DLC coatings on stainless steel 
                         substrates. A thin amorphous silicon interlayer was used to reduce 
                         DLC films total stress and to improve the films adhesion on the 
                         substrates, using silane as the precursor gas. A conventional 
                         profilometry technique was used to measure the total stress and 
                         thicknesses. The film microstructure was studied by means of Raman 
                         scattering spectroscopy. Nano-indentation was used to measure the 
                         hardness on DLC films. The friction coefficient measurements and 
                         the scratching tests were done by using a tribometer. Results of 
                         the deposition rates, total stresses, hardness degrees, structural 
                         properties, friction coefficients, and adherence tests as a 
                         function of the pulsed-DC voltage will be presented.",
