Titanium and its alloys, particularly Ti6Al4V, which is widely utilized in the marine aerospace industries, have played a vital role different manufacturing industries. An efficient cost-effective way of joining this metal by laser welding. The effect power welding speed on tensile, microhardness, microstructure Ti6Al4V alloy investigated paper. Results show that microhardness highest at fusion...

BACKGROUND High strength porous titanium implants are widely used for the reconstruction of craniofacial defects because of their similar mechanical properties to those of bone. The recent introduction of electron beam melting (EBM) technique allows a direct digitally enabled fabrication of patient specific porous titanium implants, whereas both their in vitro and in vivo biological performance...

In this paper an effect of capsule-free hot isostatic pressing (HIP) on the porosity and mechanical properties different cold spray deposits was experimentally evaluated. The HIP post-treatment significantly decreased (more than 2 times) 316L pure titanium deposits. densification porous Ti6Al4V deposit less pronounced. Mechanical after were also improved. particular, tensile strength stainless ...

Surface roughness has been considered as an important influencing factor for cell response. The aim of this study was to find out whether MC3T3-E1 cells, a mouse osteoblast-like cell line, can sense the amplitudes of surface topography of titanium alloy (Ti6Al4V), and if surface-dependent cell morphology would be presented on the substrata with varied roughness. A series of polished samples (Ra...

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...

To obtain satisfactory welds in positional laser beam welding, it is necessary to know how process parameters will influence the quality of welds in different welding positions. In this study, the titanium alloy Ti6Al4V sheets were laser welded in two vertical welding positions (vertical up and vertical down), and the appearance, porosity, strength, and ductility of the laser joints were evalua...

3D-printing techniques are attracting a lot of interest in the sensors community as promising fabrication processes that guarantee customizability at low costs. In this work, first uniaxial Ti6Al4V alloy accelerometer is designed, fabricated through Laser Powder Bed Fusion (L-PBF) technique and tested. Experimental tests under accelerations show good agreement with theoretical predictions. With...

This work presents the results of electron-beam welding commercially pure α-Ti (CP-Ti) and Ti6Al4V (Ti64) alloys. The structure mechanical properties formed welded joints were examined as a function power electron beam. beam was set to P1 = 2100 W, P2 1500 P3 900 respectively. X-ray diffraction (XRD) experiments performed in order investigate phase composition fabricated joints. microstructure ...

Due to increasing bacterial resistance antibiotics, surface coatings of medical devices with antimicrobial agents have come the fore. These on were basically thin that delaminated from due fluid environment and biomechanical activities associated in-service implants. The conventional methods manufacturing been used alloy metal-based (MBA) such as Cu Ti6Al4V enhance its antibacterial properties ...
