This work focuses mainly on making and study steel conductors with inhomogeneous surface conductivity and its effect on material behavior under generation of high pulsed magnetic fields. Monotonically changing resistivity was realized by pack chromizing steel grades 30KhGSA and 40Kh which were treated at 1000°C in argon under different conditions. An approach to investigate the resistivity distribution across diffuse layer after steel chromizing is proposed and some results are presented. To achieve a discrete change in resistivity., a powder technology is proposed that involves the use of a base steel powder., e.g. ., 30KhGSA., and compositions based on it with chromium addition to form a layered structure. The results obtained on single layer samples made of powders are discussed.
