A pulsed galvanostatic anodic dissolution of chromium−nickel steels (types Kh18N10 (Cr18Ni10) and KhN35VT (CrNi35WT)) under the conditions of electrochemical machining is studied in chloride, nitrate, and mixed chloride−nitrate electrolytes at current densities up to 100 A/cm 2 . In all the considered solutions (except for the dissolution of CrNi35WT in chloride solutions), for relative pulse durations s  2 (duty cycle D  50%), the faradaic rate of dissolution reaches a limiting value of ~0.18 mg/C, irrespective of pulse duration (from 20 s to 2 ms), which translates into the current efficiencies of alloy dissolution of 50 and 68% for the Cr18Ni10 and CrNi35WT alloys, respectively. Using direct current for processing (i.e., s < 2) boosts the current efficiency, and the rise in surface temperature is crucial to this effect.

Application of a convective method and a combined method employing a high-frequency current alongside convection for drying kernels of apricot stones is experimentally studied. The drying rate, the drying rate constants, and the duration of the first and second periods are determined. The effect of a high-frequency electromagnetic field on the kinetics of the drying is analyzed.
