METHOD AND DEVICE FOR ELECTROLYTIC DEPOSITION OF COATING

摘要

FIELD: process engineering.SUBSTANCE: invention relates to electroplating and can be used for repair of gas turbine guide vanes. This invention is implemented as follows. Vane (120, 130) makes the cathode and has surface to be coated that confines critical zone (21) with anode (19). Plating bath is filled with insoluble particles. Said vane is placed on support (12) to working position relative to support wall (14). Support (12) is placed in plating bath for co-precipitation of particles and anode metal (19) to make coating (20) on aforesaid surface. Note here that said anode (19) is arranged to face said critical zone (21). Said support (12) is provided with current line control means to make coating (20) of preset depth, relatively constant for critical zone (21), and gradually decreasing to almost zero along the edges of said coating (20).EFFECT: coating resisting oxidation and corrosion shaped to prevent whatever disturbance of aerodynamic flows, ruled out further machining, for example, by cutting.14 cl, 7 dwg
