In this study, we fabricated poly(3-hydroxybutyrate-3-hydroxyvalerate) (PHBV) coatings doped with Gd3+ (1, 5, and 10 × 10−4 mol/L) on Ti6Al4V alloy for the first time to promote soft tissue sealing around dental implants. The corrosion resistance of Gd3+-modified PHBV-coated was studied by electrochemical immersion tests, respectively, whereas CCK-8 RT-PCR evaluated biocompatibility human gingi...

Although laser-assisted turning (LAT) has been studied for decades, little is known on the effect of bulk temperature rise and residual in workpiece. Here we report an investigation a comparison characteristics LAT Ti6Al4V alloy laser heating Al/SiC metal matrix composite (MMC) as two materials have significant differences thermal conductivities. The research shows that at low cutting speed wit...

In this study, an advanced ceramic conversion surface engineering technology has been applied for the first time to self-drilling Ti6Al4V external fixation pins to improve their performance in terms of biomechanical, bio-tribological and antibacterial properties. Systematic characterisation of the ceramic conversion treated Ti pins was carried out using Scanning electron microscope, X-ray diffr...

Previous studies have demonstrated increased functions of osteoblasts (bone-forming cells) on nanophase compared to conventional ceramics (specifically, alumina, titania, and hydroxyapatite), polymers (such as poly lactic-glycolic acid and polyurethane), carbon nanofibers/nanotubes, and composites thereof. Nanophase materials are unique materials that simulate dimensions of constituent componen...

The paper presents the method of the argon - shielded hot pressing of titanium alloy (Ti6A14V) powder (used in medical industry). The powders produced in the GA (gas atomization) process and in the HDH (hydride - dehydride) process were used in the experiments. A pressing process was conducted at a temperature of 800-850 degrees C for different lengths of time. An unoxidized sintered material, ...

The aim of this study, is to use finite element simulation to achieve the optimal geometry of a broaching tool that creates the lowest tensile stress at the machined surface of the Ti6Al4V alloy. It plays a major role in reducing production costs and improves the surface integrity of the machined parts. The type and amount of residual stress determined by the thermal and mechanical loads transm...

Abstract Machining of titanium alloy Ti6Al4V is a challenging task for the industry; however, there are some solutions to overcome these difficulties. One those optimizing machining parameters. made by additive manufacturing an emerging future and even more difficult when comparing standard alloy. There lot invention on Ti6AL4V 3D printed samples, but influence post-printing lacking. In alloy, ...
