Abstract :In this study, the effect of nano-TiN layer obtained by PVD method on tribological behaviour of X210Cr12 insert ignore into journalissuearticles values(1.2080, AISI D3); cold work tool steel was investigated. Coating process was carried out by cathodic-arc PVD method using 200 V voltage, 350 °C temperature, 4x10-4 mbar pressure, and 50 A current application conditions. The characterization of the coating was carried out by FESEM and SEM-EDS analysis. The coated and uncoated samples were subjected to abrasive wear test against to 220 mesh sandpaper under 3 different loads insert ignore into journalissuearticles values(5, 10, and 20 N);. The tests were applied at three different sliding distances insert ignore into journalissuearticles values(100 m, 200 m, and 600 m); keeping the sliding speed as constant at 2,6 m/s. For uncoated samples, while the applied load increased from 5 N to 20 N, the approximate wear loss increased by 10 and 8.5 times, respectively. The approximate wear loss increased by 2.2 and 12.2 times, respectively in nano-TiN coated samples. When compared to the coated and uncoated samples, the wear loss values obtained in the coated samples at sliding distances of 100 m and 200 m differed greatly from uncoated samples, under same conditions almost 100%. However, when the sliding distance reached 600 m, the gap started to close and the gap decreased to 30%.
