Dry Sliding Wear Behavior of Laser Clad WC/NiCrBSi Metal Matrix Composite Coatings

Abstract:

Different types of WC/NiCrBSi metal matrix composite coatings were deposited by laser cladding. The wear resistance of these composite coatings was tested with a ring-on-disc (MMG-10) apparatus. The morphologies of the worn surfaces were observed using a scanning electron microscopy (SEM) equipped with an energy dispersive spectroscopy (EDS) for elemental composition. The results showed that the wear resistance of the laser clad WC/Ni-based composite coatings increased significantly with increasing WC mass fraction. It had also been suggested that the composite coating containing 60 wt% agglomerate WC had superior wear resistance property. The wear mechanism was then discussed on the basis of microscopic observations of the worn surfaces.
