摘要
An instrument for inspection of the hardening and tempering quality based on measurement of the magnetic moment after partial demagnetization of magnetized parts is described. The RK-2 instrument uses the method of pulsed magnetization and partial demagnetization of a residually magnetized part with a magnetic field pulse of specified amplitude. The pulsed magnetization is done in a solenoid with the use of a preparatory current pulse of negative polarity and a subsequent magnetizing pulse of positive polarity.
