The sliding wear behavior of an iron-base NOREM 02 hardfacing alloy was investigated in the temperature range of 25 250 ? C under a contact stress of 103MPa (15ksi). With increasing temperature, the wear loss of Norem 02 in water increased slightly up to 180 ? C at which Norem 02 showed the wear loss of 2.1mg. The wear resistance of Norem 02 resulted from the surface hardening due to the strain-induced phase transformation from austenite to α 'martensite during sliding wear. The wear loss of Norem 02 was smaller in water compared to air at same temperature because the water could be served as a sort of lubricant. The wear mode of NOREM 02 changed abruptly to severe adhesive wear at 190 ? C and galling occurred above 200 ? C . It was caused that the strain- induced phase transformation took place below 180 ? C while not above 190 ? C . Therefore, Norem 02 was considered to be inadequate at high temperature service area.
