Influence of Hf on the structure, thermal stability and oxidation resistance of Ti-Al-N coatings

Ti1−xAlxN coatings with cubic structure are widely applied in advanced machining and other high temperature applications due to their excellent mechanical and thermal properties. Recently, alloying to tailor the properties of Ti-Al-N coatings attracts considerable interest. Here, we investigate the effect of Hf on structure and thermal properties of Ti-Al-N coating with cubic structure. Alloying with 3 at.% Hf slightly promotes the spinodal...
