Phase stability, mechanical properties and thermal stability of Y alloyed Ti–Al–N coatings

The increasing demand for Ti1 − xAlxN protective coatings, especially when applied on cutting and milling tools, trigger further studies to enhance their wear performance at high-temperature conditions. To obtain requirements such as high oxidation and corrosion resistance and simultaneously high hardness and elasticity, the formation of quaternary alloys with 4d–transition metals such as yttrium (Y) is a promising approach. In order to study...
