Abstract

A new method of plasma-chemical synthesis with activation of initial substances by an optical pulsating discharge in high-velocity gas flows is used for the first time to synthesize nanostructured coatings from carbon or silicon carbonitride compounds, synthesize carbon nanoparticles, and for nanostructured modification of the iron surface. Record injection rate (for plasma-chemical methods) of energy into the gas volume (>10⁹ W/cm³), high cooling rate (~10¹⁰ K/s), and the possibility of obtaining equilibrium plasma with a temperature of up to 20-30 kK open up wide possibilities for the development of effective laser-plasma nanotechnologies.
