Abstract

The processes of laser burning and ignition on the surface of refractory metal (such as Zr, Ni, Hf) are researched in this paper. The regime of gas phase limit, at which the metal heating leads to the high temperature fusion of nitrogen compounds on their surface under condition P_limit. P has been performed, and it leads only to the creation of oxide compounds at P_limit. < P. It is shown that nitrogen creation has been a sharp appearance of new phase in the target heating dynamics. It is possible that its diagnostic as a non-stable metal burning product in the air could be done by optical method registration of non- monotonous changing of reflect capability R of the foliated system 'metal - oxide'.
