APPLICATION OF COATING AND ARC EVAPORATOR TO THIS END Russian patent published in 2015 - IPC C23C14/34 

FIELD: process engineering.

SUBSTANCE: invention relates to application of protective ion-plasma coatings and can be used in machine building, for example, for protection of turbo machine working and guide vanes. Proposed method comprises placing the parts in vacuum chamber, application of electric shift potential, ionic surface cleaning and coating application of cathode material arc evaporation. Said cathode is composed by a cylindrical shell with magnetic retainer of cathode spots area. Retainer can form the cathode spots as a strip directed along cathode cylindrical shell lengthwise axis. Said retainer displaces along the path coaxial with the circumference of cathode cylindrical shell with maintenance of its orientation. Reciprocation of cathode spots area on said strip is performed by the changeover of polarity of cathode opposite ends. This unit exploits the cathode central position in vacuum chamber.

EFFECT: uniform coating.
