Yaryza-Stetsenko A. Improving the technology of arc surfacing of the layer with variable chemical composition by its doping from the flux

The object is the process of arc deposition of a layer of variable chemical composition under the layer of alloying ceramic flux. The subject is an area of forming of layer of variable chemical composition during its arc deposition with determination of terms and methods for controlling the process of alloying of welding pool, which allows optimization of operating characteristics of deposited layer; equipment, materials and technological process of deposition of working layer with variable chemical composition. The purpose of the work is increasing of deposited layer' quality. Used methods are numerical and experimental research of arc deposition process under the layer of ceramic flux. The result is discovery of the new features of flux melting during arc deposition. The technological process and the automated equipment for arc deposition of layer with variable chemical composition are developed. Application areas: engineering, metallurgy.
