A pilot installation for the vacuum-arc discharge treatment of the surface of metals and alloys for the preparation of the production process of the deposition protective coatings on articles made from construction materials is developed. Its design and working characteristics are presented. The prototype of an arc evaporator with an arc magnetic field functioning at nitrogen pressures in a working chamber of 10-1000 Pa, arc currents of 20-250 A, and voltages across a long arc up to 50 V is developed. It is shown that the properties of the surface layer of a steel sheet after its posttreatment storage under conditions of increased humidity for several years remained invariable.
