Research on the wear properties of HVOF sprayed nanostructured WC-17Co coatings

摘要

Nanostructured WC-17Co coating was prepared by means of High Velocity Oxygen Flame (HVOF) technique.When eroded with quartz sand,the erosion wear resistance of nanostructured coating is better than that of 1Cr13.The loss of Co-rich phase dominates the main failure mechanism,following with minor peeling of WC particles.
