METHOD AND APPARATUS FOR ELECTRIC SPARK ALLOYING Russian patent published in 2001 - IPC

FIELD: processes for electric current treatment, mainly for strengthening surfaces of different metallic parts of machines and mechanisms. SUBSTANCE: disc type rotary body of apparatus includes system for automatically interrupting application of working pulses to apparatus. Compact roller-shaped electrodes and deforming members are mounted on disc body of apparatus with possibility of free rotation around their axes. Rolling friction is provided between alloying electrodes and deforming members at one side and strengthened surface of part at other side. EFFECT: enhanced efficiency of alloying process, improved quality of part coating. 4 cl, 3 dwg, 4 tbl
