Gas-jet synthesis of diamond

The nonequilibrium processes in flows of gas mixtures on the way to surface, where diamond structures formation takes place, are discussed. The main attention is focused on processes with thermal activation. Thermocatalitical phenomena in the collision of hydrogen and methane molecules with tungsten, nonequilibrium processes during transportation of active components in channels and on the way to the substrate, formation of gas atmosphere immediately close to the surface of diamond formation - all these processes relate to the field of modern physical mechanics. This statement can be related to the diamond synthesis from microwave plasma which is determined by generation of plasma from high frequency radiation and in most cases diffusion interaction of plasma with surface of deposition. The main content of studies in the Institute of Thermophysics belongs to a new direction of research, to synthesis of diamond from high velocity flow of gas mixtures or plasma.
