Abstract

The article is devoted to the results of a laboratory and industrial study that shows that the suggested criterion can be used as an integral diagnostic parameter of the state of new and old (operating) parts made of a ferromagnetic material. The main criterion in diagnosing the equipment by the method of magnetic memory of the metal is the determination of the zones of stress concentration (SC) on the surface of the controlled part, which are characterized by changes in the sign of the field of residual magnetizationH sc or a line on the surface characterized by a zero normal component of the fieldH sc. The fieldH sc is measured by a special IMNM-1F magnetometer produced by the Énergodiagnostika Research and Production Association.
