Ternary transition-metal boron nitride Ti-B-N has emerged as an outstanding material system in the field of protective coatings due to its high hardness and temperature stability. In particular, its large number of equilibrium and metastable phases offers numerous possible compositions for investigating and understanding structural effects and their influence on mechanical properties. With prior interest in chemical compositions close to the TiN-TiB line in the corresponding equilateral concentration triangle, Ti-B-N coatings were prepared using a Ti-TiN-TiB2 target containing 10 at.% B. Focusing on the investigation of single-phase structured super-hard (H≥40 GPa) Ti-B-N coatings, the influence of various deposition conditions on the structure and mechanical properties during non-reactive DC magnetron sputtering - compared to nanocrystalline Ti-B-N - comprises this study. The results show - consistent with previous ab initio calculations - that up to 10 at.% B can be incorporated into the face-centered cubic (fcc) TiN lattice.
