The possibility of forming on the surface of the product by arc deposition a layer with variable chemical composition with a predefined distribution of properties is considered. With the arc deposition of a layer of variable chemical composition, there are some difficulties for obtaining its high quality realization caused by the influence of the molten base metal of the welding pool on the distribution of chemical elements along the length of the deposited layer. When surfacing such layers with the use of ceramic alloying fluxes, there is a limit on the number of alloys that are introduced into the welding pool from the flux without impairing of the surfacing quality. This problem is solved through the use of arc surfacing with a tape electrode, which provides a minimum share of the base metal in the weld, as well as the inclusion of arc spraying technology during the formation of the working layer by arc surfacing, which makes it possible to introduce additional alloying elements into the weld pool. Currently, the process of arc spraying is carried out at equal feed rates of the electrodes in the metallizer. The electrodes have the same chemical composition and the electric arc is supplied with direct or alternating current. A variant of the metallizer design is proposed, which allows controlling the chemical composition of the deposited metal through the use of two electrodes of different chemical composition, while the metallizer has the ability to separately control the feed rates of these electrodes. By adjusting the ratio of the feed rates, while ensuring at a constant level the total mass rate of their melting (feed), one can change the chemical composition of the sprayed layer. The paper presents schemes for the implementation of the metal arc spraying process of a layer with variable chemical compositionReferences
