THE INFLUENCE OF CRYOGENIC TREATMENT ON THE HARDNESS OF ROLLING BEARINGS’ BALLS Open
This study examines the effects of Deep Cryogenic Treatment (DCT) applied after conventional quenching (Q) and tempering (T) on the hardness of rolling bearing balls—a geometric shape that has been significantly less studied compared to ot…
