Bio-tribocorrosion in dental applications
(2013-01-01)
In the oral cavity, materials (including our natural teeth) are exposed to a complex environment, which results in simultaneous mechanical, electrochemical, and microbiological solicitations. Therefore, bio-tribocorrosion ...
Tribocorrosion behaviour of bio-functionalized porous Ti surfaces obtained by two-step anodic treatment
(2020-04-15)
A bio-functionalized porous surface was obtained on Ti by a two-step anodic treatment and its corrosion and tribocorrosion behaviour were evaluated. The first-step provided macro-porosity while the second-step, a ...
First insight on the impact of an osteoblastic layer on the bio-tribocorrosion performance of Ti6Al4V hip implants
(Elsevier B.V., 2015-01-15)
In uncemented Ti6Al4V hip implants, the bone-stem interface is subjected to cyclic loading motion driven by the daily activities of the patients, which may lead to the complete failure of the implant in the long term. It ...
Future Needs and Challenges in Tribo-Corrosion Research and Testing
(Astm International, 2013-01-01)
Tribo-corrosion is an emerging interdisciplinary subject that spans from basic research on the behavior of surfaces in mechanical contact in chemically active surroundings to the test methods needed to quantify its effects, ...
Improved tribocorrosion performance of bio-functionalized TiO2 nanotubes under two-cycle sliding actions in artificial saliva
(2018-04-01)
After insertion into bone, dental implants may be subjected to tribocorrosive conditions resulting in the release of metallic ions and solid wear debris, which can induce to peri-implant inflammatory reactions accompanied ...
Wear and Corrosion Interactions on Titanium in Oral Environment: Literature Review
(2015)
The oral cavity is a complex environment where corrosive substances from dietary, human saliva, and oral biofilms may accumulate in retentive areas of dental implant systems and prostheses promoting corrosion at their ...
Growth Mechanisms and Tribocorrosion Behavior of Bio-Functionalized ZrO2 Nanoparticles-Containing MAO Coatings Formed on Ti-40Nb Alloy
(2021-06-01)
Tribocorrosion resistance, low elastic modulus, and faster promotion of osseointegration are among the current requirements to avoid aseptic loosening in artificial joints. Therefore, in this work, a promising orthopedic ...
Titanium surface bio-functionalization using osteogenic peptides: Surface chemistry, biocompatibility, corrosion and tribocorrosion aspects
(2018-05-01)
Titanium (Ti) is widely used in biomedical devices due to its recognized biocompatibility. However, implant failures and subsequent clinical side effects are still recurrent. In this context, improvements can be achieved ...
