The effect of tribo-chemical reactions under varying sliding speed and load conditions on the friction and abrasive wear response of high-velocity oxy-fuel-sprayed WC–10Co–4Cr coating was studied. The abrasive wear rate and friction coefficient decreased with the increase in sliding speed while friction coefficient displayed increasing trend with increase in load. The decrease in friction coefficient and wear rate was attributed to formation of tribo-oxides and surface films with good lubricating properties. Severity of abrasive wear increased with increasing load which was associated with transition in wear mechanisms from plastic deformation and fatigue to delamination cracking, intergranular fracture and splat fracture. Increase in friction coefficient with load irrespective of sliding speed was due to increasing contribution of fracture-assisted mechanical wear as compared to oxidative wear. The nature, composition and properties of tribo-films imparted crucial role to influencing friction and abrasive wear of WC–10Co–4Cr coating.
