ELECTRIC ARC EVAPORATOR WITH SECTIONAL REVOLVING CATHODE Russian patent published in 2011 - IPC C23C14/32 

FIELD: machine building.

SUBSTANCE: electric arc evaporator consists of cooled cylinder cathode in form of cylinder ferrule rotating around its proper lengthwise axis. The evaporator is equipped with devices for supply and withdrawal of cooling medium, devices of electrical connection of the cathode with a source of electric power supply of charge and devices for location of position of a cathode spot on surface of cathode evaporation. Also, the cathode is made sectional with set of rings, ends of which form angle from 30 to 80 degrees to lengthwise axis of the ferrule, and with two end-capping rings, in which one end forms a right angle with lengthwise axis of the cylinder ferrule, while another forms angle equal to angle of the end of the contacting it ring from the said set. Both rings are interconnected on ends and form a continuous cylinder ferrule. Rings contacting each other are made out of dissimilar materials.

EFFECT: increased operational reliability.
