Özet
This study investigated the effect of deep cryogenic treatment (-140 degrees C) on the wear resistance, hardness, wear rate and electrical conductivity of X153CrMoV12 steel. The results showed that with deep cryogenic treatment, the friction coefficient was increased by 64.67% compared to that of traditional heat treatment. In addition, it was observed that fine carbide was formed, the carbide rate increased, and the particles were homogeneously dispersed by the deep cryogenic treatment. The difference in the wear rate of deep cryogenic treatment 2 (Cry-2) and deep cryogenic treatment 1 (Cry-1) sample was 33.6 and 29.6% higher than that of the conventional heat treatment (CHT) sample, respectively. The microhardness value of Cry-2 and Cry-1 sample was 9.9 and 8.3% higher than that of the CHT sample, respectively. With Cry-2, the wear rate was reduced by 50.7% compared to CHT samples.
