In order to evaluate performance and wear of gear cutters and coatings, various analogy cutting tests are nowadays used. Since these state-of-the-art tests significantly differ in complexity and comparability to real dry hobbing applications, this wo

Zr 1 − x Al x N hard coatings were synthesised by cathodic arc-evaporation from ZrAl targets with different Al contents and applying two bias voltages, –40 and − 120 V, during deposition. Subsequently, the coatings were annealed in ambient air
