APPARATUS FOR APPLYING COATINGS ONTO DIELECTRICS IN DISCHARGE CONDITIONS Russian patent published in 1997 - IPC

FIELD: coatings. SUBSTANCE: apparatus contains vacuum chamber, arc evaporator, support to dispose a part connected with negative contact of power source. To reduce temperature at which coating condenses onto dielectrics, prevent damaging surface being treated by microarcs, and increase adhesion of coatings at orthogonal fall of ion beam onto dielectric surfaces, apparatus additionally has insulator placed on support with protective housing installed on it and electrically insulated screen disposed between evaporator and protective housing. Dimensions and shape of the screen are determined from projection of part onto support. Screen has square holes, their period, distance between screen and part, and relative size of square being determined in accordance of a certain relationship. EFFECT: increased reliability of procedure. 3 cl, 1 dwg
