Toughening of complete solid solution cermets by graphite addition
(Elsevier, 2015)
(Ti0.95Ta0.05)(C0.5N0.5)-Co complete solid solution cermets (CSCs) were developed by a mechanochemical synthesis process and a pressureless sintering method. The effect of different percentages of graphite used as a sintering ...

Porous titanium substrates coated with a bilayer of bioactive glasses
(Elsevier, 2020-09)
Porous titanium substrates coated by dripping-sedimentation technique with a novel bilayer of (45S5 / 1393) bioactive glasses are proposed to overcome some limitations of the use of titanium for implants, such as the stress ...

Synthesis and deposition of silver nanoparticles on porous titanium substrates for biomedical applications
(Elsevier, 2021-01)
Ti implants are highly biocompatible and allow orderly bone growth but, unfortunately, in the first five years after implantation, 5–10% of them fail due to poor osseointegration and to the presence of bacterial infections ...

Porous beta titanium alloy coated with a therapeutic biopolymeric composite to improve tribomechanical and biofunctional balance
(Elsevier, 2023-05)
Tooth loss is common in patients struggling with dental cavities, periodontal diseases, and tumors, as well as those who abuse tobacco or drugs. In this scenario, dental implants have become the primary treatment option ...

Synergistic Effect of rhBMP‐2 Protein and Nanotextured Titanium Alloy Surface to Improve Osteogenic Implant Properties
(MDPI, 2021-03)
One of the major limitations during titanium (Ti) implant osseointegration is the poor cellular interactions at the biointerface. In the present study, the combined effect of recombinant human Bone Morphogenetic Protein-2 ...
