The composition and parameters of magnetron plasma have been examined for the case of MoS2 target sputtered in argon. In experiments, the magnetron discharge was operated in DC and pulsed modes with f = 1–100 kHz repetition rate. Density and temperature of electrons were measured with a Langmuir probe. Coating thickness was measured with a surface profiler after the deposition. Coating density was evaluated by a weighing method. Phase composition of coatings deposited in different regimes was determined by XRD. The adhesive properties of films was measured with a scratch tester. MoS2 coatings deposited on AISI316L steel and CuAl9NiFe4Mn1 bronze samples with different surface roughness underwent tribological tests in vacuum, at 250°С temperature, with a 3-mm-radius indenter. Friction and wear tests were produced with the track length equal to 1 km.
