Formation and Strengthening Mechanisms of Plasma Sprayed Nanostructured WC-Co Coating

  • Received Date: 10 Jan 2008

  • Nanostructured and conventional WC-Co coatings were prepared by plasma spray to investigate the formation and strengthening mechanisms of the nanostructured coatings.The results indicate that typical nanostructures exist in the nanostructured coating.The sub-particles of 2-5 nm in size dispersing in the WC grains act as crystallization nuclei,which is beneficial to the formation of nanostructured coating.The hardness,elastic module,fracture toughness and bonding strength of the nanostructured coatings are higher than those of the conventional coatings,with the grain-refining being the main strengthening mechanism.
