METHOD OF ELECTROLYTE COATING APPLICATION ONTO INTERNAL SURFACE OF SMALL CROSS-SECTION ITEM, AND DEVICE FOR METHOD IMPLEMENTATION

摘要

FIELD: electrics.;SUBSTANCE: method involves submersion of item with anode mounted in it into electrolyte, connection of negative power source pole to the item and positive pole to anode, coating application by electrolyte flushing through internal item cavity. Anode is made of wire inserted into perforated tube and is connected to power source at two sides regardless of item length. Wire inside perforated tube is the conductive cord of anode.;EFFECT: uniform coating of internal surface for items with small cross-section, including long items and items with complex profile, due to simplified method and device.;6 cl, 2 dwg, 1 ex
