Abstract:
WC92Co8
coating produced by electrospark deposition effectively improves the
surface performance of the substrate. The behavior of the interface
between the WC92-Co08 coating and the substrate is studied. The high-
melting-point WC92-Co08 is deposited onto the surface of Ti alloy, and
the coating is usually more than 50 mm thick. The surface of the coating
is mainly composed of TiC and W2C besides a small amount of W, and its
micro hardness reaches 1 129 HV.The coating dramatically improves the
performance of the substrate.
