Two types of torches have been studied: a conventional one: gas stabilized plasma (GPS) with an effective power Peff = 18 kW and a more exotic one: water stabilized plasma (WSP) with Peff = 139 kW. Besides their power levels, their main difference lies in the plasma gas specific mass downstream of the anode attachment almost 10 times lower in GSP than in WSP with correspondingly the plasma temperature 10000 K higher than for WSP. TheGSP oxidation is promoted by the convective movement induced within the liquid metal droplets by the plasma flow in the jet core. In-flight oxidation shows strong similarities for both techniques with mainly the formation of non-stoichiometric FexO.
