Since decades, protective hard coatings with thicknesses of a few micrometers are grown by
physical or chemical vapor deposition (PVD, CVD) on cutting tools to improve their …

A variety of cutting tool materials are used for the contact mode mechanical machining of
components under extreme conditions of stress, temperature and/or corrosion, including …

Hard coatings used to protect engineering components from external loads and harsh
environments should ideally be strong and tough. Here we study the fracture toughness, K …

In tribological applications, the degradation of metallic coatings due to oxidation and thermal
softening at high temperatures is an issue of increasing concern. Recently, researchers …

Friction and wear are two critical tribological factors that instigate unavoidable failures of
moving components in the mechanical system. Additionally, these factors have a huge …

The impact of configurational entropy, enthalpy, and strain energy on the phase stability of
high-entropy materials has not yet been investigated quantitatively. We used ab-initio …

The influence of the non-metal species on the oxidation resistance of transition metal
ceramic based thin films is still unclear. For this purpose, we thoroughly investigated the …

Abstract Although Ti x Al 1-x N has been thoroughly studied, it is still unclear how Ti x Al 1-x
N coatings annealed for extended duration behave from a structural point of view, and if …

Extreme cooling rates during physical vapor deposition (PVD) allow growth of metastable
phases. However, we propose that reactive PVD processes can be described by a gas–solid …

An extensive understanding about the microstructural evolution and thermal stability of the
metastable AlCr (Si) N coating system is of considerable importance for applications facing …
