After initial discharges in the electrical discharge machining (EDM) process, iron plasma appears due to steel workpiece vaporarization. This study deala 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, viz., for temperature up to 10000 K, pressure range of 0.1-1Mpa, different amount of iron, and several EDM plasma radii. The presence of iron vapor has considerable influence on the thermodynamicand radiative properties of EDM arc plasmas.
