Biocompatibility testing of differently structured titanium implants was performed using an in vitro test system of a newly established human fetal osteoblastic cell line (hFOB 1.19). Cell adhesion of osteoblastic cells on the different porous geometries and the suitability of a copper vapor laser system for surface structuring was tested with the following parameters: cell-number, cell viabili...

The selective laser melting process, commonly known as laser-based powder bed fusion (LB-PBF), enables the production of structures with unprecedented degrees freedom that represents an excellent condition for development metallic implants biomedical applications. Herein, effects energy density on relative and microstructure (presence internal defects) cp-TiGd2 fabricated by LB-PBF are studied....

Abstract Dental implants are especially susceptible to bacterial adhesion and so microbial contamination. Several techniques have been explored in order obtain implant surfaces enriched with silver (Ag). The main challenge is a bactericidal effect keeping the surface biocompatible. In this regard plasma-assisted deposition very attractive technique due its versatility low environmental impact. ...

The TA1 welded joints with different heat inputs were obtained by a fiber laser and their microstructure, mechanical properties corrosion resistance in simulated saliva solution studied. results show that the microstructure fusion zone (FZ) is needle-like ?? martensite lath-shape martensite, of heat-affected (HAZ) zigzag ? phase. With increase input, volume fraction decrease coarsened FZ, but t...

Commercial pure titanium offers excellent biocompatibility, but its properties are poor for some biomedical applications where both mechanical and biocompatibility required. The study attempts to evaluate the developement ofTi–Zr alloys using conventional powder metallurgical techniques by mixing elemental (BE) or (MA) as a function of zirconium content (6, 15 20 wt-%). Sintering was performed ...
