Titania nanotube (TNT) coatings were produced using low-potential anodic oxidation of Ti6Al4V substrates in the potential range 3-20 V. They were analysed by X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). The wettability was estimated by measuring the contact angle when applying water droplets. The bioactivity of the ...

Advanced glycation end products (AGEs) irreversibly cross-link proteins with sugars and accumulate at a higher age and in diabetes, processes which can interfere with the integration of implants into the tissue. Glyoxal is a highly reactive glycating agent involved in the formation of AGEs and is known to induce apoptosis, as revealed by the upregulation of caspase-3 and fractin (caspase-3 bein...

Mechanical surface treatments have a long history in traditional engineering disciplines, such as the automotive or aerospace industries. Today, they are widely applied to metal components to increase the mechanical performance of these. However, their application in the medical field is rather rare. The present study aims to compare the potential of relevant mechanical surface treatments on th...

Acoustic Emission (AE) Technique is a unique Non Destructive Testing method being used as a global online monitoring tool for detection, location and characterization of various kinds of active defects. This paper illustrates the attempt to find the AE response of Ti6Al4V Alloy in different heat treatment conditions during tensile testing. Ti6Al4V alloy is tested in mill annealed, beta annealed...

Abstract The bonding mechanisms of a wide range metallic materials in cold spraying have been studied, mainly attributed to adiabatic shear instability (ASI) at high strain rates, whereas the impact and deformation behavior entropy alloys (HEAs) onto various substrates has not widely explored. HEAs characterized by excellent strain-hardening ability resistance localization, which can influence ...

INTRODUCTION: The majority of interbody devices for spine fusion are PEEK. Other interbody devices use a rough 2D titanium surface or full porous titanium or tantalum cores, which have been shown in-vitro and in-vivo to promote osteoinduction and osteointegration, respectively. Combining the increased osteogenic environment that titanium provides and the minimized subsidence and radiolucency fr...
