Abstract The idea to grow diamond from the gas phase was born in 1950s but it took about 30 years until first layers directly grown on substrates were shown Japan by Matsumoto and co-workers. During of research function atomic hydrogen, various growth methods process parameters investigated. Research primarily focused applications for wear-resistant tools. For this topic interactions like hardm...

This study aimed to evaluate and better understand the mechanical crystalline responses of polycrystalline silicon sawn by diamond wire sawing. To simplify multi-wire sawing kinematic, an endless saw with a single looped welded was used. The cutting speed feed rate were varied in order characteristics surface morphology, roughness, subsurface damage. analysis brittle-ductile transition residual...

The Southwest Iberian Middle Bronze Age culture, although widespread in southern Portugal and nearby areas of southwest Spain in the Middle Bronze Age, is characterised by the scarcity of preserved human remains. Recent reanalysis of the human remains unearthed from the grave cists of the necropolis of Casas Velhas (Melides, Portugal), with a minimal number of 21 individuals (19 adults and 2 no...

Atomic force microscopy (AFM) is a powerful tool for studying tribology (adhesion, friction, and lubrication) at the nanoscale and is emerging as a critical tool for nanomanufacturing. However, nanoscale wear is a key limitation of conventional AFM probes that are made of silicon and silicon nitride (SiNx). Here we present a method for systematically quantifying tip wear, which consists of sequ...

Diamond-like carbon (DLC) films are favored for wear components because of diamond-like hardness, low friction, low wear, and high corrosion resistance (Schultz et al., Mat-wiss u Werkstofftech 2004;35:924-928; Lappalainen et al., J Biomed Mater Res B Appl Biomater 2003;66B:410-413; Tiainen, Diam Relat Mater 2001;10:153-160). Several studies have demonstrated their inertness, nontoxicity, and t...
