Manufacturing method of tungsten carbide (WC)-based cemented carbide sintered body

摘要

The present invention relates to a cemented carbide sintered body mainly composed of tungsten carbide (WC), which is composed of tungsten carbide and (WC) carbides of Group 4A, 5A and 6A metals, nitrides , Carbonitride, and cordierite is mixed with an iron-based metal to prepare a WC powder having a particle size of 0.4 microns (m) or less in the powder metallurgy method, and the WC crystal according to sintering has a (0001) plane Type cemented carbide sintered body of the present invention.
