In this paper, hydroxyapatite-carbon nanotube/titania (HA-CNT/TiO(2)) double layer coatings were successfully developed on titanium (Ti) substrates intended for biomedical applications. A TiO(2) coating was firstly developed by anodization to improve bonding between HA and Ti, and then the layer of HA and CNTs was coated on the surface by the sol-gel process to improve the biocompatibility and ...

The behavior of cleavage crack fronts at grain boundaries in free-standing silicon thin films is investigated through a microtensile experiment. In addition to the crystallographic orientation, the orientation of grain boundary plane also plays a critical role. With respect to the initial crack surface, if the inclination angle is relatively small, the crack tends to penetrate across the bounda...

Lead Zirconate Titanate oxide (PZT) thick films with thicknesses of up to 10 μm were developed using a modified sol-gel technique. Usually, the film thickness is less than 1 μm by conventional sol-gel processing, while the electrical charge accumulation which reveals the direct effect of piezoelectricity is proportional to the film thickness and therefore restricted. Two approaches were adopted...

X-ray absorption spectra can be collected in multiple ways, each exhibiting a different probing depth. The total electron yield signal contains contributions from primary, Auger and secondary electrons. We present data on the total electron yield probing depth at core level energies ranging from 77 to 929 eV. By coating materials with chromium overlayers, we find that the maximum probing depth ...

Abstract Cutting edge declaration strategies and the progression of advanced troublesome coating materials are fundamental for making high-quality mechanical components. The point this work is to induce prepared CrN coatings by magnetron sputtering at unmistakable nitrogen stream rates look effect moving on composition, film thickness properties gotten chromium nitride coatings. outcomes appear...

Insufficient bone anchoring is a major limitation of artificial substitutes for connective osteoarticular tissues. The use of coatings containing osseoconductive ceramic particles is one of the actively explored strategies to improve osseointegration and strengthen the bone-implant interface for general tissue engineering. Our hypothesis is that hydroxyapatite (HA) particles can be coated robus...
