Micro arc oxidation of Ti-15Zr-7.5Mo alloy
(2016-01-01)
Ti-15Zr-7.5Mo alloy was melted and its structure and mechanical properties were evaluated, followed by micro-arc oxidation (MAO) treatment to add bioactivity. Melted Ti-15Zr-7.5Mo alloy was consisted of mainly β containing ...
Influence of the molybdenum on characteristics of oxide films produced by micro-arc oxidation on Ti-15Zr-based alloys
(2021-02-25)
Micro-arc oxidation (MAO) is a powerful tool to modify the surface of Ti alloys, in order to increase the lifetime of orthopedic implants. It is well established that the resulting oxide films are dependent on the parameters ...
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 ...
Effect of bio-functional MAO layers on the electrochemical behaviour of highly porous Ti
(2020-03-25)
Ti foams are attractive for orthopaedic applications due to reduced Young's modulus and ability of bone in-growth. However, poor corrosion behaviour and lack of bioactivity are yet to be overcome. In the present work, ...
Micro-arc oxidation as a tool to develop multifunctional calcium-rich surfaces for dental implant applications
(2015)
Titanium (Ti) is commonly used in dental implant applications. Surface modification strategies are being followed in last years in order to build Ti oxide-based surfaces that can fulfill, simultaneously, the following ...
Morphology, crystalline structure and chemical composition of MAO treated Ti-15Zr-Mo surfaces enriched with bioactive ions
(2019-01-01)
In this study, MAO treatment was used to enrich, with bioactive Ca, Mg and P atoms, as-casted and heat-treated Ti-15Zr-xMo (x = 0, 5, 10 and 15 wt%) alloys, for potential use as advanced metallic biomaterials. The chemical ...
Physical characterization and biological tests of bioactive titanium surfaces prepared by short-time micro-arc oxidation in green electrolyte
(2022-02-01)
Titanium (Ti) and its alloys are the most used biomaterials in dental and orthopedic implant applications. However, despite the good performance of these materials, implants may fail; therefore, several surface modification ...
Bulk and surface design of MAO-treated Ti-15Zr-15Mo-Ag alloys for potential use as biofunctional implants
(2020-06-15)
This study investigated the effect of silver addition and micro-arc oxidation (MAO) treatment on the microstructure, selected mechanical properties, and surface characteristics of the Ti-15Zr-15Mo (wt%) alloy. The ingots ...
TiO2 bioactive implant surfaces doped with specific amount of Sr modulate mineralization
(Elsevier B.V., 2021-01-01)
One of the main problems that remain in the implant industry is poor osseointegration due to bioinertness of implants. In order to promote bioactivity, calcium (Ca), phosphorus (P) and strontium (Sr) were incorporated into ...
Understanding growth mechanisms and tribocorrosion behaviour of porous TiO2 anodic films containing calcium, phosphorous and magnesium
(Elsevier B.V., 2015-06-30)
The growth of the dental implant market increases the concern regarding the quality, efficiency, and lifetime of dental implants. Titanium and its alloys are dominant materials in this field thanks to their high biocompatibility ...
