The effects of heat treatments on abrasive wear strenght of sand cast DIN X210Cr12 cold work tool steels

The samples used in this study were produced using the sand casting method. The produced samples were produced with and without Mo (Molybdenum) reinforcement. Heat treatment was applied to the produced samples by using comparison parameters such as different temperature, waiting time and cooling environment. The heat treated samples were polished and SEM images were taken and the internal structures of the samples were examined. The samples were subjected to abrasive wear test under different loads using sandpaper, depending on certain time and distance parameters. Results after the wear test; The effects of applied load, amount of wear and presence of Mo were compared. Micro Vickers hardness measurements of the samples were made. As a result of experimental studies, it has been determined that certain heat treatment parameters and Mo reinforcement give positive results on the hardness and wear resistance of cold work tool steel.
