This study investigates the influence of heating rate on the tribological and corrosion properties of 52100 bearing steelsamples consolidated via spark plasma sintering. The consolidation was conducted at different heating rates of 50, 100,200, 300, and 400 °C/min and the thermomechanical properties of the resulting samples were characterized. Ball-on-disctribological tests and electrochemical techniques were used to evaluate the wear and corrosion resistance, respectively. The results showed that an increased heating rate positively affects the thermomechanical and tribological properties of52100 bearing steel. The sintered samples exhibited a low coefficient of friction (between 0.4 and 0.56) and a low wear rate(between 1.4 and 1.8 × 10−6 mm3/Nm) at heating rates between 100 and 400 °C/min. Furthermore, the corrosion resistanceof the samples gradually drops above the heating rate of 100 °C/min. The samples can be ranked in the order of decreasingcorrosion resistance thus: 100 > 200 > 300 > 400 > 50 °C/min. The improved corrosion resistance of the sample sintered at100 °C/min can be attributed to its refined crystal size and high density.
