The process of carburization is the oldest and has been most extensively employed in industry as a method of case hardening of steels. The progress in the carburization technique, however, has not been extremely rapid. Therefore a new method with higher rate of penetration and better quality of case is extensively craved for. To find a solution of this problem, electrodischarge carburization has been conducted by the present authors to combine electrodischarge heating and the carburizing action in a special electrolyte. This is a method of case hardening of steels in a electrolyte that contains the chemicals required to produce a case comparable with one resulting from liquid carburization. This provides a convenient method of carburization, with low distortion and with considerable high rate of penetration and uniformity of control of the case.
The best carburizing conditions obtained in the present study are as follows:
electrolyte: ethleneglycol saturated with sodiumchloride
applied voltage: 150 V DC
carburizing time: 1∼5 min
case depth: 0.2∼0.3 mm
hardness of the case: >Hv 850
