Claim Text:
1. A torch system for deposition of protective coatings onto the walls of holes and recesses present on a flat surface of an object, the system comprising: a plasma reactor for generation of an atmospheric-pressure inductively coupled plasma torch having an axis and a high-temperature core surrounded by an electron cloud producing a spatial charge with a potential minimum on the axis of the plasma torch and ended by a torch tip with a crossover facing the object, the plasma torch tip having a conical shape; an RF inductor that surrounds the plasma reactor and is connected to an RF power supply; means at one end of the plasma reactor for supplying a gaseous medium to sustain the plasma torch and a precursor for the formation of a protective coating; a plasma torch focusing device positioned at the end opposite to said one end of the plasma reactor; an object holder that supports the object and is moveable relative to the plasma reactor and the focusing device; a first driver for moving the focusing device coaxially to the direction of the plasma torch; a first controller that is connected to the first driver and controls operation thereof; a second driver and a third driver for moving the object holder with the object in mutually perpendicular directions, respectively, in a plane perpendicular to the axis of the torch; a second multichannel controller connected to the second driver and a third driver for controlling their operation; a fourth driver for moving the object holder with the object in the direction of the axis of the torch; and a third controller that is connected to the fourth driver for controlling operation thereof.
