What Is Carburization?

Carburizing refers to excessive carbon content after sintering of cemented carbide. The ideal carbon content of tungsten carbide in cemented carbide (WC) is 6.13% by weight. When the carbon content is too high, the product will have obvious carburized structure. There will be obvious excess free carbon in the product.

Free carbon will greatly reduce the strength and wear resistance of tungsten carbide cemented carbide. The C-shaped hole in the phase detection indicates the degree of carburization.
