FIELD: instrument making.
SUBSTANCE: method is characterised by using DC source, electrolysis math with window in wall covered with elastic insert for tight fixation of covered samples, cover with anode and cathode, such as each sample, at sides or faces of which coating is applied. Each sample is placed into through slot congruent with its shape arranged in elastic insert, which tightly covers bath window from outside and is fixed with application of frame that tightly presses insert to bath wall. Bath is filled with electrolyte, anode is submerged, and electric current is supplied using current conductors arranged in inserts and contacting with samples, until specified parametres of coating are obtained.
EFFECT: making it possible to simultaneously apply local coating at samples of various shape with area of coverage from 0,5 mm2, excluding additional current losses and exhaustion of electrolyte.
