METHOD OF APPLICATION OF PROTECTIVE COATINGS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC C23C14/24 C23C14/50 

FIELD: technological processes.

SUBSTANCE: device comprises at least one pair of opposing vacuum-arc evaporators with a common electrically insulated anode for each pair and one pair of gas-discharge ion sources forming the annular processing zone of the products. Each evaporator is arranged to move along their axis of location. The electrically insulated holder of the articles to be processed is made in the form of a first rotation shaft arranged on the axis of the annular processing zone of the products and a second rotation shaft. The first rotation shaft is coaxially covered by the outer shaft, the second rotation shaft and the outer shaft are connected by a transfer mechanism of the rotation pulse from the first rotation shaft to the second rotation shaft. The second rotation shaft is movable along the radius of the annular treatment zone of the articles and around the first rotation shaft. The positive pole of the source of displacement with the electronic key is connected to the body of the vacuum chamber.

EFFECT: providing the possibility of applying to products with a curved surface, including turbine blades, blink, blades and nozzle blocks of gas turbine engines, various dimensions, protective and protective hardening coatings from plasma with a high thickness uniformity with reduced energy consumption, increasing the productivity of the coating process and simplifying the design of the device.
