The Effects of Abrasive Conditions on the Performance of Tungsten Carbide-Based Metal Matrix Composite Overlays

Typically, standard alloys do not have the wear resistance properties necessary to combat the aggressive wear and corrosive conditions prevalent throughout the oil sands mining process.  For production-critical components, it is common to apply tungsten carbide-based metal matrix composite (WC-MMC) overlays to extend equipment life and prevent unplanned outages.  The performance of composite overlays is very much dependent on the wear-environment.  This paper will discuss how the interactions between abrasive conditions and the mechanical and structural properties of the WC-MMCs are key in determining the resultant levels of performance.  Such information can lead to a better selection of materials and subsequent extended component life.
