Notes:
Sliding wear mechanisms of the solution treated 18Cr-18Mn-2Mo-0.9N high nitrogensteel (HNS) were studied. Room-temperature dry sliding wear tests of the steel were carried out atvarious applied loads to explore the mechanism as a function of the load. The wear rate of the steelincreased with the increase of the load; however, the increase rate was not constant. The rateincreased slowly at low loads, rapidly at intermediate loads, and finally, the increase-rate becamelow again at high loads. Worn surfaces, their cross sections, and wear debris were examined, andphases of the heat-treated HNS as well as the wear debris were identified to find out the mechanism.The wear of the steel was found to be controlled by the tribo-oxidation, strain-induced phasetransformation, and reverse transformation due to temperature rise on a wearing surface. Theinfluence of each mechanism on the rate varied depending on the magnitude of the applied load
