Abstract The oxidation resistance of Hf0.28B0.72 and Hf0.11Al0.20B0.69 thin films was investigated comparatively at 700 °C for up to 8 h. Single-phase solid solution thin films were co-sputtered from HfB2 and AlB2 compound targets. After oxidation a

Abstract In this work, we studied the energetics of diffusion-related quantities of transition-metal impurities in TiN, a prototype ceramic protective coating. We use ab-initio calculations to construct a database of impurity formation energies, vaca

We present a first-principles study of pressure- and temperature-dependent diffusion barriers and coefficients for vacancy-mediated and interstitial V impurity and Ti self-diffusion in TiN. The thus obtained diffusion coefficients were fitted with an

Mechanical properties of nanoscale multilayer coatings are to a large extent governed by the number of interfaces and their characteristics. While for a reduced layer thickness, increasing strength and toughness values have been reported, properties
