SEM of micro scratch grooves; (a) WC-Co scratch groove exhibits significant cracking, indicative of an embrittled binder, inset: lower magnification image of a WC-Co scratch groove exhibiting cracking and large debris particle, (b) WC-Co-10ND scratch groove does not exhibit any significant cracking, groove is smooth indicative of a ductile binder, inset: lower magnification image of a WC-Co-10ND scratch groove showing significantly reduced cracking and debris.
