Wear behavior of differently cryogenically treated AISI H13 steel against cold work steel

The effect of different cryogenic treatments on the wear behavior of chromium base die steel under dry condition has been examined at five levels of sliding velocity and normal loads. Parameters chosen for cryogenic treatment cycles are subjected to soaking duration of 6, 21, and 36 h at soaking temperatures of -154 celcius and -184 celcius. Soaking period of 21 h shows higher wear resistance, whereas 36 h treatment shows the reduction in wear resistance. Worn out surface and wear debris exhibit that mechanisms responsible for wear of samples are rupturing of martensitic matrix and delaminating.
