AbstractIn this study; the effect of nitration process applied to coldforged 32CrMoV1210 samples with 100-mm, 24, 5 mm in outer diameter and 7, 5 mm in inner diameter, which is used in production of the barrel rifle, on the abrasion behaviour is investigated. For this purpose, hardness measurements, microstructure investigation and coating thickness determination of the gas nitrated 32CrMoV1210 steels at 500 °C for a period of 12 hours has been carried out. The original sample and the heattreated sample have been subjected to an over ring pin-type abrasion test under 80N-120N load. While the 1.2344 (X40CrMoV51) quality tool-steel, which is 56(HRC) in hardness, is used as a pin, the materials which have been examined with nitration and without nitration are used as a ring. In comparison with the severe abrasion resistance of 32CrMoV1210 samples without nitration; nitrided samples have shown an increase in abrasion resistance at the rate of %90.
