In this study, the electrochemical properties of pure cobalt wire and cemented tungsten carbide were examined by anodic and cyclic polarization measurements to investigate the corrosion resistance of cobalt and cemented tungsten carbide in wiredrawing lubricants. It was found that the synergic effect of stress and leaching could be the answer for severe cracking of cemented carbide dies in the wet drawing process.
