Intensification of the anodic erosion in electrospark alloying by the employment of pulse group

Fabrication of Bioactive Coatings on Steel Substrates by Electro-Spark Deposition (ESD) and Micro-Arc Oxidation (MAO) Methods

“…1c) values of coatings rise as well. These behaviors are characteristic of the ESD coating process [3,5]. It is clear that the properties of the MAO process depend on the quality of the previous ESD process and it is shown that the coating number (pass number) of 5 and pulse current amplitude of 300 A are optimum pulse parameters in the ESD coating process (Fig.…”

“…In the present study, a special ESD machine [5], equipped with an electrode, was employed. AISI 1060 steel substrates (cathode) with a size of 20 × 20 mm 2 and titanium alloy (Ti6Al4V) (anode) were used in the ESD coating experiments.…”

A Study on Modification of Micro-Alloy Steel Surfaces with Different Hard Materials Via Electro-Spark Deposition Method

“…The ESD coating system was de-* corresponding author; e-mail: korkmazk@gyte.edu.tr scribed in detail in previous studies [8,9]. Hard alloys electrode materials were deposited on the microalloy steel samples in air, using a series of rectangular shape pulses of certain duration of 100 µs and with amplitudes of current between 100200 A.…”

Electrospark Deposition: Mass Transfer

“…Part of the ejected molten mass could be transferred to substrate and the rest is wasted. The ejected mass, so the transferred mass, could be increased by the employment of pulse groups instead of employing individual pulses (Rybalko et al, 1998;Ribalko et al, , 2008. Mass transferred to the substrate could also be increased by the choice of an optimum scanning rate of the treating electrode.…”
