METHOD OF CHROMIUM PLATING OF PLUNGERS AND PLUNGER PAIRS AND DEVICE FOR ITS EMBODIMENT Russian patent published in 1999 - IPC

Abstract RU 2130514 C1

FIELD: electrochemistry, in particular, methods and means for electrodeposition used in process of parts reconditioning. SUBSTANCE: method includes placement of treated part into electrolyte and passing of electric current between the part serving as cathode and anode submerged into electrolyte. In this case, part is given rotary motion at linear speed of any point of treated surface equalling 0.3-0.7 m/min. Device for method embodiment includes bath for electrolyte with pairs of parallel anodes installed over its length and system of suspensions for treated parts. Each suspension has horizontal pulley installed for rotation round vertical axis and fastened with part holders. Power supply system is connected with anodes and treated parts. Drive with regulated rotation speed is connected by means of V-belt transmission with all pulleys of suspension system for treated parts. EFFECT: higher microhardness and wear resistance of reconditioned plungers and plunger pairs. 2 cl, 2 dwg
