Structural changes in the surface layers titanium, electro-spark alloying electrodes made of graphite

Abstract

The phase-structural transformations have been investigated in titanium surface layers after electrospark alloying (ESA) by graphite electrode. Titanium samples measuring 15x15x4 mm have been made of commercially clean titanium sheet. Its brand is BT1-0. The graphite rod of brand C-3 of 6 × 200 TU 16-538-019-69, being 40 mm at length and 6.0 mm in its diameter have been used as an anode (machining electrode). ESA process has been carried out in the energy range of W values of electrical discharges varying from 0.3 up to 3.0 J.
