Surface Layer Formation at Dynamic Combined Exposure by Two-Component Electrode

Abstract

Abstract This article is devoted to the study of workpieces surface layer state, resulting from dynamic exposure of a two-component electrode with imposition of electric field. The objects considered in the work are details with complex profile. Such parts are used in aviation, rocket and space technology and in oil and gas industry. They include impellers and flow part of turbopump bodies, augers, blade wheels, which have areas of variable curvature with limited tool access to treatment area. The authors show that mixture in combined process of two-component processing media from current-carrying granules and conductive liquid medium supplied at high speed to the treatment area, provides the required quality of surface layer due to the combined dynamic exposures on the material being treated. The parameters combination of electric field and kinetic energy of conductive granules allows you to control the magnitude and depth of material hardened layer in treatment area. Experimental studies have shown the increase in resource and durability of critical assemblies for aerospace equipment and oil and gas apparatus.
