First principle calculations of nanolayered ZnO polymorphs (Wurzite–, Zincblende–, Rocksalt–structures) in the scheme of density functional theory were performedwith the help of full potential linear augmented plane wave (FP-LAPW) method. Theexchange - correlation potential is described by generalized gradient approximation asproposed by Perdew–Burke–Ernzrhof (GGA–PBE) and modified Becke–Johns...

This paper aims to investigate the diffusion bonding of Ti6Al4V Al2O3. The potential use reactive nanolayered thin films will also be investigated. For this purpose, Ni/Ti multilayer with a 50 nm modulation period were deposited by magnetron sputtering onto base materials. Diffusion experiments performed at 800 °C, under MPa and dwell time 60 min, without interlayers. Microstructural characteri...

AlCr-based hard nitride coatings with different chemical compositions and architectures have been successfully developed applied over the last few decades. Coating properties are mainly influenced by deposition conditions Al/Cr content. The fcc structure is dominant for an Al-content up to Al0.7Cr0.3N preferred most cutting applications. Different (AlCrX)N alloying concepts, including X = Si, W...

The machining process is still a very relevant in today’s industry, being used to produce high quality parts for multiple industry sectors. processes are heavily researched, with the focus on improvement of these processes. One improvements was creation and implementation tool coatings various operations. These improved overall productivity tool-life, new developed applications. TiAlN present d...
