Abstract
Abstract: This paper deals with the additive manufacture of magnesium alloy products of the magnesium-aluminum-manganese-zinc system by plasma surfacing with a reverse polarity current. Special attention was paid to the following points: studying the influence of evaporation of alloying elements during plasma additive surfacing on the material quality; studying the influence of surfacing modes (continuous filling and layer-by-layer filling with cooling at different thermal cycles) on the formation of structure and properties of the synthesized material; specifying the influence of the heat treatment on the structure and properties of the deposited metal. A correct selection of plasma surfacing parameters eliminates porosity and cracks in deposited layers. It is established that plasma surfacing provides a relative structural and phase stability of the previous layers under the influence of subsequent thermal cycles during the workpiece manufacture. In general, the dispersion of the structure of the deposited MA5 alloy is significantly higher than that of the cast and heat-treated metal structures produced by conventional technologies. Plasma surfacing with a reverse polarity current provides a deposited metal with high mechanical properties, i.e. a unique 5–9-fold increase in ductility compared to the cast material with an increase in ultimate strength by 7–10%, both with and without heat treatment.
