FIELD: quality control of the hardened surface of articles after high-energy treatments.
SUBSTANCE: method consists in measurement of voltage drop on hardened layer with subsequent calculation of total electric resistance as per specified value of electric current force and measured voltage drop, note here that high-frequency signal is used to create required measurement depth, its frequency being calculated proceeding from hardened layer thickness.
EFFECT: technical result is measurement of total electrical resistance of a reinforced layer of articles as an index of quality after processing.
