Tungsten carbide coercive magnetism is the magnitude of the reverse magnetic strength required to completely demagnetize a magnetic material. The coercivity magnetism of carbide decreases with increasing cobalt content and increases with finer grain size. The coercivity magnetism is measured to examine the basis for process variation. For example, if carburization is present in the alloy, the coercivity magnetism is low, and if decarburization is present in the alloy, the coercivity magnetism is high. If the alloy is underfired, the coercivity is high, and if the alloy is overfired, the coercivity is low. Therefore, the coercivity is also a very important test to ensure the quality of the alloy.
WC-Co cemented carbide is magnetic because of the presence of magnetic Co phase, and coercivity is one of the important parameters which can reflect the grain size and distribution of the alloy. The study and analysis of the formation mechanism and factors influencing the coercive magnetism of cemented carbide, the use of alloy coercive magnetism can be used to non-destructively test the relevant properties of the alloy, and in turn, the quality of the alloy can be improved by controlling the coercive magnetism of the alloy.
