| Abstract: |
The present investigation shows the fabrication procedure of bimodal WC-VC-Co coatings processed by the HVOF thermal spray process. The effects of nanostructured phase contents on the microstructure and wear resistance of the coatings are included. Special attention is drawn to the mapping of elastic properties within the cobalt matrix, which were measured by nanoindentation. Finally, the influence of VC additions on the size, morphology and stability of the WC phase is also discussed.
