Dynamic Combined Treatment of Curved Surfaces by Two-Component Processing Media

Abstract

Abstract This article is devoted to the tool usage as conductive filler with application of electric field for dynamic dimensional finishing combined treatment of hard-to-reach surfaces with high degree of curvature. The area of its technological use is shown in relation to aircraft engineering, rocket and space technology component parts and oil and gas industry. The common criterion for method applicability is that such parts have sections with variable curvature and limited tool access to the treatment area. The authors show that in dynamic combined process control of the required technological and operational indicators is possible due to the combination of current-carrying granules kinetic energy and surface anodic dissolution in treatment area. Methods for remote control of dimensional processing with the creation of required reinforced surface layer due to the dynamic mechanical action of solid granules and surface roughness due to anodic dissolution of work surface are presented. The resulting effect is increase in service life and durability in critical assemblies of aerospace equipment and oil and gas apparatus.
