Production and simultaneous deposition of ultradisperse particles on a substrate in a pulsed atmospheric-pressure gas discharge traveling over the surface of electrodes in the self-magnetic field

A method of production and simultaneous deposition of ultradisperse particles is described. In this method, a metal is melted and sprayed in a high-power pulsed arc discharge traveling over the surface of electrodes in the self-magnetic field. The discharge is initiated in air or an inert gas at atmospheric or low pressure. An experimental setup intended for this method provides a power density on the cathode of 10$^8$–10$^{10}$ W/cm$^2$. Such values are comparable to those obtained in a vacuum arc or with pulsed laser radiation. Ultradisperse catalytic particles deposited by this method on the polymer membranes of hydrogen fuel cells are several nanometers across and offer a high adhesion to the membrane.
