An analysis of melting processes during the laser plasma synthesis of metal nitrides in a high-pressure nitrogen atmosphere
Abstract
The thermal processes associated with the laser plasma synthesis of metal nitrides in a high-pressure nitrogen atmosphere are analyzed with allowance for a complex time dependence of the energy flux reaching the metal surface resulting from the shielding actin of the laser cloud. The results obtained are found to be in good agreement with experimental data on the synthesis of titanium nitride. It is shown that auto-oscillations in the system laser-plasma-target result in an oscillatory motion of the melting-solidification front which may be one of the factors responsible for the formation of multilayer structure of synthesized layers.
