Osseointegrated dental implants play an important role in restorative dentistry. However, plaque accumulation may cause inflammatory reactions around the implants, sometimes leading to implant failure. In this in vivo study the influence of two physical hard coatings on bacterial adhesion was examined in comparison with a pure titanium surface. Thin glass sheets coated with titanium nitride (Ti...

Laser beam welding has wide acceptability due to least welding distortion, low labour costs and convenient operation. However, laser welding for dissimilar titanium and aluminium alloys is a new area which is having wider applications in aerospace, aircraft, automotive, electronics and other industries. The present study is concerned with welding parameters namely laser power, welding speed, fo...

TiC-Ti-Al mixed powders and TC4 titanium alloy foils were overlapped layer-by-layer in the graphite die. The TC4-based laminated composite sheets reinforced by Ti aluminide and carbide were successfully fabricated via spark plasma sintering (SPS) at 1100 °C with a well-bonded interface. The composite layers were mainly composed of TiAl, Ti₃Al, Ti₂AlC, and Ti₃AlC₂ phases. The carbides particles ...

The present study aimed to investigate whether bone marrow-derived mesenchymal stem cell (BMSC) sheets combined with titanium implants enhanced implant osseointegration in an ovariectomized (OVX) rat model of osteoporosis. Sprague-Dawley rats were randomly assigned into a test group and control group. Allogenic BMSCs were collected from the rats, cultured and stored via cryopreservation. At 6 m...

Abstract Titanium and its alloys take attention, especially in aerospace, automotive, biomedical applications because of their strength, corrosion resistance, biocompatibility. components, general, are produced by sheet metal forming. However, the springback effect is a critical problem forming process due to difficult formability titanium sheets. In present study, hot was applied sheets invest...

This study proposes a direct synthetic route to single titanate sheets through the mild and versatile conditions of the “chimie douce”. The stages of the production include the complexation of the titanium alkoxide precursor by benzoic acid, the formation of titanium oxo-clusters and their controlled transformation into single sheet titanates during the hydrolysis stage. The resulted material a...

Abstract: titanium sheets in pure molten aluminum at 750 and X-Ray Diffraction Analysis results, TiAlintermetallic layer thickness increases slowly at primary stages. After that an enhanced growth rate occurs due to layercracking and disruption. Presumably, reaction starts with solving titanium into the molten aluminum causing intitanium super saturation and TiAlintermetallic layer which conseq...

in this work, the strength of cold roll bond of the commercially pure titanium (cp ti) sheet and the effect of tio2 nanoparticles on bond strength was investigated. through the accumulative roll bonding process, which is considered among the important severe plastic deformation processes, the creation of suitable bonds plays a significance role in the ultimate strength of the bond. thus, resear...
