چکیده انگلیسی
Increasing requirements on hard coatings in high performance machining processes like high speed and dry cutting demand further development by alloying the already well established Ti1âxAlxN coatings. The aim of this work is to present a comparative study on quaternary Ti-Al-X-N (X = Hf, Nb, B) coatings sputtered from targets with an Al / Ti ratio of 2 and 5 at.% X in an Ar + N2 discharge. Special emphasis is laid on investigating structural, mechanical and tribological properties. X-ray diffraction showed that a more pronounced hexagonal structure appears due to the incorporation of these alloying elements thus affecting the hardness. Hf and Nb additions yield similar friction and wear properties up to 700 °C, whereas the B containing coating failed at 700 °C. Widening of the ternary metastable Ti1âxAlxN solid solution to quaternary systems is the key to further develop these coatings.
