STEP MODEL OF EROSION OF ELECTRODES. II. APPLICATION TO THE CASE OF SPECIAL REGIMES OF ELECTROEROSION TREATMENTL. I. Sharakhovskii,a A. Marotta,b and A. M. Esipchuka UDC 621.387.143.014.31 The possibility of applying the step model of erosion of cold electrodes [Inzh.-Fiz. Zh., 76, No. 2, 116-122 (2003)] for special (optimized) regimes of electroerosion treatment of metals has been shown. A satisfactory agreement between the theoretical calculations and the experimental data of other authors [J. Appl. Phys., 66, No. 9, 4095-4103 (1989)] in electroerosion treatment of steel has been obtained. aA. V.
