Parsazadeh, Mohammad, Fisher, Gary, McDonald, André, Hogan, James D.
Sliding wear was simulated for tungsten carbide-nickel (WC-Ni) composites with different WC particle sizes and volume fractions under various normal forces. Johnson-Cook and Johnson-Holmquist models were employed to simulate the mechanical behaviour of the Ni and WC phases, respectively. Using...

Friction Stir Processing (FSP) of Thermal-sprayed Tungsten Carbide-Nickel (WC-Ni) MMC Coating
DownloadFall 2013
Tungsten carbide-Nickel (WC-Ni) metal matrix coating with fixed powder composition was deposited using low pressure cold gas dynamic spraying (LPCGDS) and High velocity oxy-fuel (HVOF) spraying. These coatings were subsequently treated with friction stir processing (FSP) as post-deposition heat...

Tungsten carbide-based metal matrix composite coatings are deposited by PTAW (Plasma Transferred Arc Welding) on production critical components in oil sands mining. Homogeneous distribution of the reinforcement particles is desirable for optimal wear resistance in order to reduce unplanned...

High maintenance costs due to significant abrasive wear of components is experienced in the energy and mining sectors despite the current use of tough and hard coatings. During the coating process significant detrimental residual stresses may build up and result in premature failure of a...

Jibran, Wania, Hogan, James D., McDonald, André
In this study, a 33 full factorial design methodology was used to analyze the effects of spray parameters on the thickness, hardness, and surface porosity of low-pressure cold-sprayed WC-17Ni coatings. Three levels were selected for the spray parameters included in the design which were the...
