Plasma Jets for Materials Processing

This work deals with the diagnostics and
measurements of properties of DC plasma jets working
at atmospheric and lower pressures. Great efforts
have been devoted to study the non-equilibrium
efects generally observed at low pressure. The DC
plasma torch investigated is of the type used for
the deposition of different powders. DC plasma jets
are characterized by their relatively high electron
density and very high specific energy (of the order
of 1022 m-3, and 108 J/kg respectively). Owing to
their ability to heat, melt, and, in some cases,
vaporize the material under treatment, DC plasma
jets have gained many practical applications in the
field of materials processing such as plasma
deposition and spraying of different materials on
various substrates.

from University of Sherbrooke in Canada in 2001. He performed
his PhD studies on low pressure supersonic plasmas, and
diagnostics of plasma jets used for materials engineering. He
has held research positions at the University of Sherbrooke and
Ecole Polytechnique, Montreal.
