Recent accreditation of titanium powder products for commercial aircraft applications marks a milestone in titanium powder metallurgy. Currently, powder metallurgical titanium production primarily relies on vacuum sintering. This work reported on the feasibility of powder sintering in a non-vacuum furnace and the tensile properties of the as-sintered Ti. Specifically, we investigated atmospheri...
Biocompatibility improvements for blood contacting materials are of increasing interest for implanted devices and interventional tools. The current study focuses on inorganic (titanium, titanium nitride, titanium oxide) as well as diamond-like carbon (DLC) coating materials on polymer surfaces (thermoplastic polyurethane), deposited by magnetron sputtering und pulsed laser deposition at room te...
PURPOSE The purpose of this study was to investigate the ion release from titanium casts in solutions of mixed organic acids and to reconsider the possibility of allergic reactions to titanium. METHODS Cast specimens were made from commercially pure titanium. For the immersion solutions, we prepared two types of organic acid solutions, one mixed with organic acids contained in whole stimulate...
Titanium has limitations in its clinical performance in dental and orthopaedic applications. This study describes a coating process using pulsed laser deposition (PLD) technology to produce surfaces of titanium carbide (TiC) on titanium substrates and evaluates the biological response both in vitro and in vivo. X-ray photoelectron spectroscopy (XPS) analysis revealed the presence of 18.6-21.5% ...
Biomedical titanium alloys with Young's moduli close to that of cortical bone, i.e., low Young's modulus titanium alloys, are receiving extensive attentions because of their potential in preventing stress shielding, which usually leads to bone resorption and poor bone remodeling, when implants made of their alloys are used. They are generally β-type titanium alloys composed of non-toxic and all...
Many biological polyelectrolytes are capable of undergoing a fluid-fluid phase separation known as complex coacervation. Coacervates were prepared using hyaluronic acid (HA) and a recombinant fusion protein consisting of mussel adhesive motifs and the RGD peptide (fp-151-RGD). The low interfacial energy of the coacervate was exploited to coat titanium (Ti), a metal widely used in implant materi...
Titanium is a metal known for its biocompatibility and corrosion resistance.1,2 Its uses in the medical field range from long-term orthopedic implants and pacemakers to daily-use articles such as eyeglass frames and ornamental body piercings.3 Metal allergies are classically known to occur with nickel, gold, cobalt, and chrome3. Titanium has not been fully recognized as an allergen; however, th...
Objective: To synthesis a series of novel titanium (IV) complexes with corresponding antibiotic drugs. Methods: A series of novel titanium (IV) complexes have been synthesized by reacting titanium tetrachloride with corresponding antibiotic drug (L) i.e. (L = A1 (tetracycline hydrochloride); B1 (Streptomycin); C1 (Cefixime); D1 (Ampicillin); E1 (Amoxicillin) in fixed 1:2 molar ratios using meth...
Flexible intramedullary nails are commonly used to treat femoral fractures in children. This study evaluated the biomechanical differences between stainless steel and titanium nails when securing transverse and comminuted fractures in a synthetic femur model. Retrograde flexible stainless steel and titanium nails placed in a divergent "C" pattern were mechanically tested, and axial rotation and...
in this research, tribological behavior of ti-ni-p intermetallic coatings on titanium substrates have been investigated under dry reciprocating conditions. hardness profile testing results exhibit that high surface hardness has been attained and static indentation result shows that the intermetallic coating has better adhesion strength than the conventional ceramic coatings. in this respect, th...
