In this contribution, nitride-based thin films relevant for machining industry are analyzed regarding their thermal and mechanical properties. In particular, the influence of the chemical composition and the coating architecture on the thermal conductivity, hardness, residual stress are studied.
Based on experimental results we show that fine tuning of the film chemical composition and controlling the microstructure are effective ways to synthesize films with a broad range of thermal conductivity values, e.g. ranging from <10 to >100 W/(mK) for doped AlN. Growing films in a multilayer architecture allows to enhance the mechanical properties in comparison to their monolithic counterparts and to realize directional-dependent thermal conductivity properties.
