From the great variety of methods to improve efficiency cutting tools, it is necessary highlight applying wear-resistant coatings, which in recent years are increasingly used. Applying coatings on tool can significantly increase its and intensify machining modes. Mechanisms strengthening coating for materials have been analyzed under impact technological parameters condensation process structur...

We propose a hypothesis that a very thin layer can be made more transparent by adding a thin coating with susceptibility of opposing sign. Two experimental tests backed by a theoretical model support this hypothesis. First, we show that the visible and near-infrared transmission through a semi-transparent silver film can be enhanced by up to ~70% and spectrally tailored depending on the type an...

The wide applicability of titanium (Ti) has prompted the analysis to improve its mechanical strength through addition different alloying elements. Among these, Ti materials with pre-mixed pure and nitride (TiN) powders as starting have exhibited improved properties tribological performance. In this study, matrix composites ring-shaped TiN dispersoids were evaluated. fabricated from powder core–...

Carbon nanotubes (CNTs) have excellent chemical durability, mechanical strength and electrical properties. Therefore, there is interest in CNTs for not only electrical and mechanical applications, but also biological and medical applications. We coated titanium, a common material for dental implants, with multiwalled carbon nanotubes (MWCNTs). First, titanium was aminated and covered with colla...

Transition metal nitride coatings films such as TiN or ZrN have been extensively studied for industrial applications. Residual stresses of the coatings generally affect the mechanical behaviour and the corrosion resistance and hence the performance of the product. The development of new, fast and simple methods for the assessment of residual stresses is then of great importance for coating tech...

Zinc oxide and Ga-doped ZnO nanowires and nanorods are synthesized on various substrate like Fluorine doped tin oxide glass plate, SiO2 coated Silicon substrate and aluminum nitride coated silicon substrates. The coating process carried out using zinc oxide sol-gel solution. The synthesized material was characterized using XRD (X-ray diffraction), FE-SEM (Field emission scanning electron micros...

The surface characteristics and friction behaviour of titanium Grade 2 with modified nitride (TiN, Ti2N) boride (TiB) compound layers were investigated. It was shown that during non-contact boriding in oxygen-containing medium titanium, the diffusion processes take place mainly by interscale mechanism; however, nitriding, besides traditional mechanism, grain boundary mechanism nitrogen atoms is...
