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 …

We review the thin film growth, chemistry, and physical properties of Group 4–6 transition-
metal diboride (TMB 2) thin films with AlB 2-type crystal structure (Strukturbericht designation …

High-entropy materials often outperform their lower-entropy relatives in various aspects,
such as thermal stability and fracture toughness. While there are extensive research …

Microstructural design has attracted increasing interest in modern development of hard
coatings for wear-resistant applications. In plasma-assisted vapor deposited thin films, the …

Grain boundary engineering is a versatile tool for strengthening materials by tuning the
composition and bonding structure at the interface of neighboring crystallites, and this …

Refractory transition-metal diborides (TMB 2) are candidates for extreme environments due
to melting points above 3000° C, excellent hardness, good chemical stability, and thermal …

Nanostructured silicon carbide has unique properties that make it useful in microelectronics,
optoelectronics, and biomedical engineering. In this paper, the fabrication methods as well …

Various approaches to creating multicomponent nanocomposite coatings of high and
superhigh hardness (from≈ 30 to 100–120 GPa) are reviewed with particular emphasis …

High elastic moduli do not guarantee high hardness because upon finite shear electronic
instabilities often occur that result in transformation to softer phases. Therefore, the author …

We systematically study the oxidation properties of sputter-deposited TiB 2.5 coatings up to
700° C. Oxide-scale thickness d ox increases linearly with time ta for 300, 400, 500, and …
