Bulk metallic glasses (BMGs) are non-crystalline class of advanced materials and have found potential applications in the biomedical field. Although there numerous conventional manufacturing approaches for processing BMGs, most commonly used like copper-mould casting some limitations. It is not easy to manage control critical cooling rate, especially when fabrication complex BMG geometries involved. Other limitations these techniques include size constraints, non-flexibility, tooling...
Abstract This study aimed to synthesize, characterize, and evaluate the adhesion strength of titania nanotubes (titania nanotubes) iodine‐doped (I‐titania architectures on additively manufactured Ti‐6Al‐4 V (Ti64) implant surface. The I‐titania were synthesized through two stages electrochemical anodization, whereby are anodically fabricated a conventional approach then modified by replacing ethylene glycol electrolyte with potassium iodide solution. characterization results revealed...
To suit a target application, the machining mechanism of electro discharge (EDM) process has been hybridized to powder mixed EDM (PM-EDM) by adding various substances in form additives into dielectric fluid. In this study, application PM-EDM fabricate Lakargiite (CaZrO3) coating on Zr–Cu–Ni–Ti–Be substrate surface for potential orthopedic using hydroxyapatite (HA) as additive was proposed. The effect HA concentrations deposition CaZrO3 investigated. bulk metallic glass (BMG) exceptional...
Porosity defects are inherently present in Ti–6Al–4V (Ti6-4) parts produced using additive manufacturing (AM) methods like laser powder-bed fusion (LPBF). This work aims to investigate different laser-inherent porosity at various LPBF parameter settings and assess their impact on the fatigue behaviour of Ti6-4 implants processed by LPBF. The presence LPBF-inherent with shapes sizes was established microstructural examination X-ray micro-CT analysis. These mostly comprise lack-of-fusion...
The aim of this study is to assess the stress distribution on bone tissue and bone-implant interface a customized anatomic root-analog dental implant (RAI) by means finite element analysis (FEA) for different types density. A mandibular right second premolar was selected from CBCT database. DICOM file converted an STL create CAD model in FEA software. boundary created, while density I–IV were determined. Von Mises measured at tissues interfaces. To validate models, RAI 3D printed through...

Bulk metallic glasses (BMGs) have exceptional biomechanical characteristics like low elastic modulus, outstanding fracture strength, superior wear and corrosion resistance compared to routinely used biomaterials. The major downside of BMG is its inability osteointegrate the surrounding living tissues. To solve this problem, a biocompatible bone-like nanoporous layer are normally imparted on implant surface. In study, very hard, nano-porous was deposited Zr-based glass surface, by...
In recent years, researchers have demonstrated increases interest in studies involving silicon carbide (SiC) materials due to several industrial applications. Extreme hardness and high brittleness properties of SiC make the machining such material very difficult, time consuming costly. Electrical discharge (EDM) has been regarded as most viable method for SiC. The mechanism EDM process is complex. Researchers acknowledged a challenge generating model that accurately describes correlation...
Zr-based bulk metallic glass (BMG) has outstanding mechanical, physical and chemical characteristics compared to currently used biomaterials such as stainless steel, titanium cobalt based alloys. However, BMG is characterized by low hardness bio-inert native oxide surface. Therefore, it does not allow tissue growth cell adhesion when implanted into the host body. This study, attempts improve surface quality of suspending a bioactive hydroxyapatite powder in dielectric fluid during electro...
In recent years, the need for Silicon carbide (SiC) ceramic arises due to several industrial applications. However, cost of machining such components is very high.
