Description
Summary:The work concerns the realization of a conductor material with monotonically changing conductivity with depth and theoretical description of magnetic and thermal effects in such systems under high magnetic fields. Thick-walled cylindrical single-turn coil of steel was used as model inductor for theoretical and experimental studying. Surface modification of medium carbon steel 30KhGSA was made by pack chromizing. Characterization of modified surface layer depending on chromizing conditions has been made. The full-scale testing the inductors made of this steel with modified surface was carried out using an inductor system with magnetic flux concentrator as a test subject under generation a magnetic field of 50 T in amplitude and 15 µs in half-period. The results are discussed.
