Abstract RU 2797563 C1

FIELD: coating production.

SUBSTANCE method for producing a multilayer gradient wear- and corrosion-resistant coating and a device for its production by electro-spark alloying in vacuum and cathode-arc evaporation of the electrode material. The deposition of the layers of the specified coating is carried out by alternately changing the voltage in the range of 20-200 V and the duration of the pulses in the range of 20-500 μs using a rotating rod electrode with an alloying annular nozzle. The lower coating layer is deposited by electro-spark transfer and cathode-arc evaporation of the electrode material only, and the upper alloyed layer is deposited by additional cathode-arc evaporation of the material of the alloying annular nozzle. The lower layer of this coating is formed at lower voltage and pulse duration than the upper alloying layer. In one of these devices, a rotating rod electrode is installed in the current lead, on which an alloying annular nozzle in the form of a truncated cone is axially fixed. This nozzle is made of a material with a lower ionization potential than the electrode material, and is installed with a smaller cone base to the workpiece. In another of these devices, inside the hollow cylindrical part of the current lead rotation unit, along its lower edge, an alloying annular nozzle is fixed with its outer edge, inside which an electrode is axially installed. The alloying annular nozzle is made of a material with a higher ionization potential than the electrode material.

EFFECT: increased wear resistance and corrosion resistance of machined surfaces of parts.
