In present paper, the influence of sliding speed, contact load, sliding time and microstructure on interface temperature during the sliding of eutectic Al–Si alloy (LM13) and hypereutectic Al–Si alloy (LM28) has been investigated. Sliding test was conducted under dry sliding conditions against hardened steel En-32 counter surface over a range of sliding speed from 0.2 to 5.0 m/s and contact load from 10 N to 30 N . It was observed that the interface temperature is a function of contact load, sliding speed, microstructure and thermal softening characteristics of sliding metal. Heat treatment of LM28 alloy decreases frictional heating and hence interface-temperature, however that of LM13 alloy does not affect the interface temperature especially under severe sliding conditions. Wear of aluminium alloys has close relationship with interface temperature. There is a critical temperature for each alloy corresponding to transition from mild to severe wear. LM28 alloy shows higher value of the critical temperature than the LM13 alloy under identical alloy conditions.
