ELECTRODE MATERIAL FOR ELECTRIC SPARK ALLOYING

摘要

surface strengthening of steel and cast iron products. SUBSTANCE: electrode material for electric spark alloying on base of white iron contains next ingredients (mass%): carbon - (4-4.5); manganese - (0.5-0.6); silicium - (0.8-0.9); ferrum - the balance. Such material has lowered melting temperature that allows to reduce erosion strength, to increase mass transfer. EFFECT: enhanced efficiency of alloying process. 1 ex, 1 tbl
