Özet
In this study, AISI 4340 (34CrNiMo6) tempered steel was applied to the plasma nitration process at different temperatures and at different periods in order to increase the wear resistance of the outer surface without decreasing the hardness of the core under 40-44 HRC, and to prevent the component from distortion during heat treatment. The sufficient core strength and tensile stress of some mechanical elements such as mold, drill, U-Drill are required not to fall below a certain value. There were five different temperatures (450, 475, 500, 530 and 550 degrees C) and two different time values (18 and 32 hours) used with these temperatures utilized in the study. The study tried to identify the optimum nitriding temperature and time for the limit values determined by considering the wear value after nitriding. The wear characteristics of the samples in dry conditions were also investigated. It was observed that the ideal target values (core 40-44 HRC) in the nitrided components were reached at 450 degrees C in 32 hours.
