发明名称 PROCESS OF MANUFACTURE OF SUPERCONDUCTIVE ARTICLES WITH INTERNAL CAVITIES BY EXPLOSION WELDING
摘要 FIELD: manufacture of superconductive solenoids, parts of electric machines working under conditions of cyclic loads and torsion. SUBSTANCE: tubular lining with powder of superconductive material is wound along spiral on cavity-forming element in the form of steel rod. Layer of fine-dispersive ceramic powder is placed between cavity-forming element with tubular lining and protective tubular interlayer. Outer charge of explosive is initiated. Process is realized with allowance for detonation rate of explosive and its specific mass. Specific masses of protective tubular interlayer and ceramic powder. On completion of process cavity-forming element is removed. Process makes it feasible to manufacture articles with density of superconductive materials close to 94-97% of its limiting value. EFFECT: manufactured articles display high resistance to formation of cracks. 1 cl, 3 dwg, 1 tbl
