Corrosion Resistance of Nanostructured Cemented Carbides with Alternative FeNi and FeNiCo Binders.

Nanostructured cemented carbides with Co binders have shown excellent mechanical properties in various applications. Nevertheless, their corrosion resistance has shown to be insufficient in different corrosive environments, leading to premature tool failure. In this study, WC-based cemented carbide samples with different binders were produced using 9 wt% of FeNi or FeNiCo with the addition of CrC and NbC as the grain growth inhibitors.
