Electromagnetic plasmadynamic systems are one of the most promising systems for a number of
applications: surface hardening, thermal spraying, surface modifications. On the surface these
systems provide the same action parameters (i.e., power density, exposure time) as technological
lasers, but they have advantages - large action spots, up to ten square centimeters and combined
thermal and shock action. These systems are capable of accelerating powder particles at the
velocity up to (2.5-3)·10 3 m/s. Using these systems the unique coatings from B4,C, Si and WC are
formed. Such high particles velocity is not attainable by other spraying. But normally these
systems operate at low pressure of ambient gas (10 2 -10 3 Pa) only and with a low frequency of
operation
