The article presents the results of experimental studies of the parameters of micro-sized metal particles and sprayed films obtained by the method of electric explosion of metallic conductors (EVP) and electro-explosive spraying (EVN), respectively. Copper (Cu) and aluminum (Al) metal wires were used as explosive conductors. Geometrical parameters and physicochemical analysis of the obtained microparticles and thin films were carried out by means of the universal two-beam electronic system Versa 3D. From the analysis of the obtained samples of sprayed thin films and fine particles, it follows that with a discharge current density J≈10 ^ 10 A / m ^ 2 millisecond, the film thickness and particle sizes can reach values ​​less than micron scale.
