Tribocorrosion properties of different type titanium alloys in simulated body fluid
TL;DR: In this paper, the electrochemical and tribological properties of β-type Ti alloys were investigated for comparing the same set of the results with and without wear test using XRD and SEM investigations and hardness measurements were utilized to analyze the structure, surface morphology and mechanical behavior of the alloys Simulated body fluid (SBF) was used as corrosive environment Tribocorrosion tests were carried out at open circuit potential (OCP), cathodic and three different anodic potentials under reciprocating sliding condition Potentiodynamic scans were obtained and calculated the friction coefficient,

TL;DR: In this study, coagulant-assisted foaming was utilized for the fabrication of porous Ti6Al4 V using egg-white foam, and Quantitative assessment of bone ingrowth by micro-computed tomography revealed that there was an approximately 52% higher bone formation and more than 90%Higher bone penetration at the center of femoral defects in rabbit when implanted with Ti6 al4 V foam.
Journal ArticleDOI
In search of representative models of human bone-forming cells for cytocompatibility studies.
TL;DR: Results show that none of the osteoblast-like cells studied perfectly mimic the behavior of human osteoblow cells (hOB) on Ti6Al4V surfaces or exposed to Ti particles.

On the mechanisms of biocompatibility.
TL;DR: It is shown that, in the vast majority of circumstances, the sole requirement for biocompatibility in a medical device intended for long-term contact with the tissues of the human body is that the material shall do no harm to those tissues, achieved through chemical and biological inertness.
