The aim of this work is to study the effect of heat treatments on the wear rate of the medium carbon steel which included normalizing and different quenching media (air, oil, salt solution at concentration %25). Quenching Include heating to a temperature of 870Co and then rapid cooling. A Pin -on-Disc technique was used to measure the wear rate under dry sliding conditions with applied and different sliding times with constant sliding speed of disc (641 r.p.m) and hardness of the steel disc (48 HRC). The results show that the wear rate increases with applied loads, and with increasing sliding time for all heat treated specimens it was found that the hardness values of the quench specimens at salt solution is higher than that of normalized specimens and quenched specimens in the oil.
