Effects of Magnetic System Unbalance on Magnetron Sputtering Characteristics
Deposition rate and ion current density distribution profiles at DC magnetron sputtering of Al, Ti and Cutargets were studied as functions of the process parameters and level of magnetron unbalance. Based onthe experimental data the distributions of the ion-to-atom ratio on the condensing surface under variousdeposition modes were calculated. It was established that in the case of DC magnetron sputtering the ionto-atom ratio on the condensing surface increased if the sputtering yield of the target’s material droppeddown. The minimal energy impact on the growing film and the most uniform distribution profile of theion-to-atom ratio were achieved by applying the I-type unbalanced magnetron system

Optical and Tribological Properties of PVD/CVD Diamond-like Carbon Films
The optical and tribological properties of diamond-like carbon (DLC) films deposited by the combination of magnetron sputtering of graphite and plasmochemical dissociation of methane were studied. It was established that at methane concentration in the gas mixture Ar/CH4 at about 5–10 % the formation of DLC films with refraction index n 2.0, microhardness larger than 1000 HK and friction coefficient of 0.06–0.08 becomes possible
