ABSTRACT
cw CO2 laser-assisted combustion of Ti and Zr in Xe:O2 and N2:O2 gaseous mixtures was studied. Total dissolution of oxide films and/or formation of oxynitride layers on both metals were evidenced and the growth of giant oxide nuclei of up to 100×10×10 μm3 was observed upon burning Zr samples.
