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 …

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 …

First-principles calculations are employed to determine the mechanical properties of rock-
salt structure binary and ternary transition metal nitrides, carbides, and carbonitrides from …

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 …

Abstract Crystalline (Hf, Ta, Ti, V, Zr) N nitride thin films, with a high-entropy metal-sublattice,
were synthesized at 440° C by reactive magnetron sputtering using an equimolar Hf-Ta-Ti-V …

The design of the appropriate material system for a given tribological application must be
guided by an accurate understanding of the degradation mechanisms and the surface …

Reactively magnetron sputtered high-entropy metal-sublattice (Al, Cr, Nb, Ta, Ti) N coatings
have been alloyed with Si concentrations between x Si= 6.4 and 15.0 at.%. All coatings are …

Phase stability and oxidation resistance are main objectives when synthesising hard and
protective coatings for applications requiring also high thermal stability. Even though TiAlN …

Abstract Single-phase crystalline (Al, Cr, Nb, Ta, Ti) O 2 high-entropy oxide thin films were
synthesized at 400° C by reactive magnetron sputtering of an equimolar Al–Cr–Nb–Ta–Ti …

Alloying a fourth element and multilayer architecture are efficient methods to tailor the
structure and properties of aluminum-containing transition metal nitrides coatings. Here, we …
