For this purpose, a number of bearing steel samples were held for different times (12, 24, 36, 48, 60 h) at deep cryogenic temperatures (-145 degrees C). The wear experiments were carried out in a ball-disk arrangement, by applying loads of 10 and 20 N and a sliding velocity of 0.15 m/s. After conducting the experimental studies, 36 h was found to be the optimal holding time. At this holding time, the wear rate and friction coefficient were decreased, while the hardness reached to maximum values. It was observed that DCT led to significant microstructural changes, which resulted in improved tribological properties.en10.1007/s12666-014-0417-4info:eu-repo/semantics/closedAccessBearing steelDeep cryogenic treatmentMicrostructureWear resistanceArticle676909917WOS:000347091100013Q2Q3
