Common degreasing defects include debinding deformation, degreasing crack, bubbling, warping, delamination and decarburization. Bubble, warping and delamination are common defects in thermal debinding process. It is one of the core of cemented carbide production control to formulate corresponding defect prevention and solution measures according to specific defects.

Main reasons causing the degreasing crack of tungsten carbide  are the segregation of the molding agent (the uneven mixing of the binder), the debinding temperature and the residual internal stress.

The structure of tungsten disulfide is a hexagonal layered structure with excellent electrical properties.
