PRRG

There are two different research areas, which we defined. One of them is the nitriding of different steel alloys, using DCPN or ASPN plasma nitriding methods. We also deal with characterization of the treated samples using optical and electron microscopy. We also determine Wickers hardness profiles of the samples.  The other research topic is the study of the plasma using local diagnostics methods involving Langmuir-probes. We developed automated data acquisition system to measure the voltage-current curve of the probes. We determine local plasma parameters of the plasma. We also move the probe using computers, so we can determine radial plasma parameter distribution.
