Hardening of the Surface of Titanium Alloy in an Alternating High-Voltage Discharge in a Flow of Liquid

Development of Two-Way Shape Memory Material on the Basis of Amorphous-Crystalline TiNiCu Melt-Spun Ribbons for Micromechanical Applications

“…The action of periodic discharge in the liquid flow (PDLF). One of promising methods for modification of material physical properties is the electrospark action that can be realized, in particular, by means of forming the periodic high-voltage discharge in the liquid flow when using a voltage source with dropping volt-ampere characteristic [47]. Special features of periodic discharge running in the liquid flow and the peculiarities of its action on the electrode material were discussed in the works [47,48].…”

Special features of periodic discharge running in the liquid flow and the peculiarities of its action on the electrode material were discussed in the works [47,48]. It has been established, that material treatment with the PDLF technique makes it possible to modify near-surface layers of material, to raise its microhardness, improve its corrosion characteristics.…”
