The paper presents the results of theoretical studies that allow predicting the formation of wear-resistant coatings on the working surfaces of machine parts by the method of carbo-vibro-arc hardening (CVAH). Analytical regularities of electric field intensity formation by oscillating carbon electrode during carbo-vibro-arc hardening (CVAH) have been established; the maximum layer thickness of multicomponent paste, 2.1...2.5 mm, which ensures stable electric arc combustion during CVAH, has been theoretically substantiated. With the increase of amplitude and frequency of oscillations of the carbon electrode, the electric field strength at CVAH decreases nonlinearly, but the thickness of the hardened layer of the multicomponent paste has the greatest influence on it. As a result, ceramic-metal coatings of high quality and integrity are formed on the hardened surfaces of parts. The testing of the obtained theoretical regularities has confirmed their reliability.
