Implementation of advanced characterization techniques for assessment of grinding effects on the surface integrity of WC-Co cemened carbides

Grinding is a key step on the manufacturing process of WC–Co cemented carbides (hardmetals). In this work, an investigation of grinding effects on the surface integrity of hardmetals is conducted. It is done by combining diverse advanced characterisation techniques: X-ray diffraction, field emission...
