                         deposition system that uses a bipolar, pulsed power supply was 
                         designed and tested to evaluate its capacity to produce quality 
                         diamondlike carbon films on the inner surface of steel tubes. The 
                         main focus of the study was to attain films with low friction 
                         coefficients, low total stress, a high degree of hardness, and 
                         very good adherence to the inner surface of long metallic tubes at 
                         a reasonable growth rate. In order to enhance the diamond-like 
                         carbon coating adhesion to metallic surfaces, four steps were 
                         used: (1) argon ion sputtering; (2) plasma nitriding; (3) a thin 
                         amorphous silicon interlayer deposition, using silane as the 
                         precursor gas; and (4) diamond-like carbon film deposition using 
                         methane atmosphere. This paper presents various test results as 
                         functions of the methane gas pressure and of the coaxial metal 
                         anode diameter, where the pulsed-DC voltage constant is kept 
                         constant. The influence of the coaxial metal anode diameter and of 
                         the methane gas pressure is also demonstrated. The results 
                         obtained showed the possibilities of using these DLC coatings for 
                         reduced friction and to harden inner surface of the steel tubes.",
