FLAT INDUCTOR FOR MAGNETIC PULSE COMPACTION OF ARTCILES FROM NANOSIZED POWDERS Russian patent published in 2011 - IPC B22F3/87 B21D26/14 

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy. Proposed flat inductor consists of inductor spiral representing Archimedes spiral, casing, interturn insulation and current leads to connect inductor to power supply. Zero and potential current leads are made up of rods with cylindrical bulge provided with groove receiving inductor bus that features double thickness and depth equal to bus height. Grooves in cylindrical bulge form transition from current lead to spiral turn made along tangential line in current lead/bus contact zone. Inductor bus permanently connected with current leads features double thickness, smoothly reducing to single thickness at the distance of, at least, current lead cylindrical section diametre.

EFFECT: longer life at discharge high powers.
