Thermal stability and machining performance of arc evaporated Ti1-xAlxN hard PVD coatings with x=0.5 – 0.73 ratios using an integrative approach

Incorporating Al into TiN-based coatings plays a key role in enhancing their mechanical properties and thermal stability which are the crucial properties for cutting tool applications. In this paper, we study the effect of different Al contents on the mechanical and thermal properties and consequent machining performance using an integrative approach. The results show that heat treatment of the Ti1-xAlxN coating decomposes them into their …
