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.
