In vitro study on cytocompatibility and osteogenesis ability of Ti-Cu alloy.
TL;DR: It was revealed that an addition of 5% Cu into pure Ti would not cause any negative effect on osteoblasts adhesion, proliferation and apoptosis cultured with Ti–Cu alloy, and Ti-Cu alloy could significantly promote the osteogenic differentiation of MG 63 cells by upregulating the osteogenesis-related gene expressions.

Influence of a large pulsed electron beam (LPEB) on the corrosion resistance of Ti−6Al−7Nb alloys
Jisoo Kim,Hyung Wook Park +1 more
TL;DR: Pulsed electron-beam irradiation was used as a finishing process for Ti−6Al−7Nb titanium alloy to increase the corrosion resistance and surface hardness as discussed by the authors, which was attributed to an increase in the density of dislocations and a decrease in the fraction of the pre-dominant slip plane.

New biocompatible near-beta Ti-Zr-Nb alloy processed by laser powder bed fusion: Process optimization
TL;DR: In this article, the laser powder bed fusion parameters were determined for a novel biomedical Ti-18Zr-14Nb (at%) alloy using both analytical and experimental approaches, and a technological processing window corresponding to a 25-45 ǫ/mm3 energy density range and a 10-25 Ǫ/h build rate range was recommended for the fabrication of the fully dense Ti- 18Zr 14Nb alloy with improved surface roughness.

Principles and prevention of corrosion
TL;DR: In this article, the technology and evaluation of Corrosion is presented, with a focus on the effects of Metallurgical Structure on Corrosions, and a discussion of materials selection and design.
Journal ArticleDOI
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.
