Effect of CrN addition on the structure, mechanical and thermal properties of Ti-Al-N coating

Optimization of Ti–Al–N coating by incorporation of fourth substantially alloying elements attracts extensive attention in order to meet the severe application requirements at elevated temperature. Here, we investigate the effect of CrN addition on structure, mechanical and thermal properties of Ti–Al–N coating with cubic structure. Alloying with CrN promotes the spinodal decomposition of Ti–Al–N to form Al-depleted and Al-enriched domains and...
