Native surface oxides, which usually contaminate metals in ambient atmosphere, limit the performance in industrial applications like coating or welding. Different deoxidation techniques were developed to remove such oxide layers. Promising results were obtained for dielectic barrier discharge (DBD) hydrogen plasmas in deoxidation of copper at 20 °C and 100 – 1000 hPa. In this study, we report the application of a DBD plasma for deoxidation of natively oxidized iron surfaces in an Ar/H2 atmosphere at 100 and 1000 hPa. Plasma treatments were performed at a discharge voltage of 10 kV and a frequency of 8.8 kHz at room temperature (RT) as well as in the combination with heating
