Abstract

Highlights: WC composites have been produced with AISI 304L as metallic binder. The corrosion resistance is comparable to the WC–Co benchmark. The localized corrosion process was analyzed by SEM and SVET. Abstract: The corrosion behavior of tungsten carbide hard metal composites with AISI 304L stainless steel as binder matrix and a WC–Co composite with similar grain size and binder content was investigated using electrochemical techniques (open circuit potential monitoring, current-potential curves, electrochemical impedance spectroscopy, scanning vibrating electrode technique) and scanning electron microscopy.
