The Palmqvist method is usually used as a measure to evaluate the toughness of ceramics and thin coatings, as these cannot be determined with classic test methods such as the tensile test or the Charpy impact test due to their brittleness or the smal

To improve the service behavior of gears, surface heat treatments such as nitriding or induction hardening can be performed. Since these processes are limited in their achievable maximum hardness or depth of hardness, a combination treatment could al
