Abstract: A method of forming a diamond-like carbon coating in vacuum, comprising the steps of: pretreatment of the surface of the pad; placing the part into a vacuum chamber; treating the surface of the part with accelerated ions; applying a sublayer of a material onto the treated surface of the part; electric are vacuum sputtering a graphite cathode from a cathode spot and producing a carbon plasma accelerating an ion component of the carbon plasma; depositing the produced carbon plasma on the surface of the part and producing the diamond-like carbon coating. A pulsed electric are discharge is used, by which a plurality of cathode spots are excited at the end surface of the graphite cathode, cathode spots moving along the end surface of the cathode at a speed of from 10 to 30 m/s and generating a carbon plasma having an ion energy of 40 to 100 eV and an ion concentration in the plasma of 1012 to 1014 cm−3, with electrically insulating the part in the vacuum chamber.
