To clarify the dry friction and wear characteristics of cast iron under the conditions of high sliding speed and high contact pressure, especially those in the state of the thermal wear, wear tests of sliding a cast iron pin on a mild steel disk were carried out with using a pin-on-disk test device. The variations of friction force and wear rate with sliding distance were measured. The temperature changes of the sliding pin were also measured using the infrared imaging system. After some sliding, the temperature of the cast iron pin near the sliding surface rose sufficiently for thermal wear to occur. In the state of thermal wear, the coefficient of friction of cast iron is independent of the contact pressure but is considerably influenced by the sliding speed and decreases with higher speed. On the other hand, the wear rate of the cast iron pin increases proportionally with the increment of contact pressure, but it is little affected by the sliding speed.
