Abrasive wear behaviour of nano-TiN coated AISI D3 tool steel

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