In dry sliding wear of H13 steel, with increasing ambient temperature and load, the wear mechansim changed from adhesive wear to oxidative mild wear and finally to oxidative wear. In adhesive wear, the specimens tempered at 600, 200 and 440 degrees C presented higher wear resistance than the ones tempered at 500, 650 and 700 degrees C. In oxidative wear, the wear resistance increased in the following order: the specimens tempered at 700, 500, 200, 650, 440 and 600 degrees C. Wear resistance was suggested to depend on hardness and fracture resistance in adhesive wear and on the formers and thermal stability in oxidative wear. (C) 2011 Elsevier Ltd. All rights reserved.
