Carbide quality control-Coercive force
Release time:2012-09-19

Coercive force refers to the residual magnet in a magnetic retardation cycle after the cobalt binder phase is magnetized and demagnetized. It is a very important harmless test method in industries due to the fact that there is a direction between the average grain size of the carbide phase and the coercive force. The finer that grain size of the carbide phase, the high value the coercive force.
