Original Abstract

After initial discharges in the electrical discharge machining (EDM) process, iron plasma appears due to steel workpiece vaporization. This study deals with the calculation of the thermodynamic properties and net emission coefficient of nitrogen-iron arc plasma. Assuming isothermal plasma in local thermodynamic equilibrium, the properties are presented according to the typical plasma parameter range of the EDM process, for temperature up to 10 000 K, pressure range of 0.1 - 1 MPa, different amounts of iron, and everal EDM plasma radii. The presence of iron vapor has considerable influence on the thermodynamic and radiative properties of EDM arc plasmas.

Keywords

Electrical discharge machining (EDM), net emision coefficient (NEC), nitrogen-iron reaction products, plasma modeling, radiative heat transfer, thermodynamic properties.
