Summary:This thesis was focused on the surface modification with plasma discharge. Austenitic AISI 316L stainless steel sample was carburised under different experimental conditions and mechanical properties have been studied (thickness, lattice parameter, elemental composition, hardness, wear resistance and corrosion resistance). After that, steel substrates have been nitrided or carburised in order to analyse their stability under ion bombardment using a plasma focus device. Helium and deuterium were the gases used in 0, 1, 5, and 10 discharges. Optical and X-ray characterisations were used. Finally, using magnetron sputtering nitrided/carburised samples were coated with an AlN thin film in order to study their stability under long treatments at high temperatures.
