The friction coefficients and wear rates of cast-iron coatings and cast-iron-cast-iron pairs in lubricated contact at different temperatures were measured using an elevated temperature wear tester. The removal mechanism of materials and the behavior of coating, substrate microstructure and precipitation particles during wear were studied by scanning electron, microscopy and energy dispersive X-ray analysis. It was shown that at higher temperatures the wear of electroplated chromium/niobium cast-iron pair was mainly caused by adhesion, but at lower temperatures the wear was a result of fatigue delamination which was controlled by the nucleation and propagation of fissures. Whether the temperature was high or low, the asperity on the infiltrated niobium layer was observed to cause abrasive wear of the liner.
