Abstract
This study is focused on WC-Co dry-electropolished by DryLyte® technology that allows to obtain corrosion-free surfaces with a roughness below 9 nm. The main goal behind this research is to investigate the surface integrity trying to correlate the remanent microstructure after different dry-electropolishing times as a function of the hardness and elastic modulus evolution though massive nanoindentation. The quality of the surface has been evaluated by using advanced characterization techniques and the mechanical response treated by using the statistical methodology proposed by Ulm and Constantinides. To sum up, a close correlation is observed between the residual microstructure and the surface integrity in terms of hardness and elastic modulus maps.
