Biomimetic apatite coatings on micro-arc oxidized titania
Biomaterials, 2004Biomimetic apatite coatings on micro-arc oxidized titania films were investigated and their apatite-inducing ability was evaluated in a simulated body fluid (1.0 SBF) as well as in a 1.5 times concentrated SBF (1.5 SBF). Titania-based films on titanium were prepared by micro-arc oxidation at various applied voltages (250-500 V) in an electrolytic ...

Optimization of the coating parameters for micro-arc oxidation of Cp-Ti
Surface and Coatings Technology, 2010Abstract TiO 2 coatings were formed on the surface of CP-Ti by AC pulse micro-arc oxidation. The structural, mechanical, corrosion and tribological properties were analyzed by using XRD, SEM, microhardness tester, surface profilometer, electrochemical polarization unit and pin-on-disk tribotester.

Micro-Arc Oxidation Treatments on Zn
ECS Meeting Abstracts, 2014Micro-arc oxidation has been a hot topic in the field of surface treatment of aluminum, magnesium and titanium for about twenty years. It consists in a high-voltage oxidation beyond the dielectric breakdown occurring at the interface metal/oxide/electrolyte. Due to the high temperature reached in the resulting plasma, the grown coatings are dry ceramic

Ceramic oxide coating formed on beryllium by micro-arc oxidation
Corrosion Science, 2017Abstract Beryllium was oxidized at a current density of 10 mA cm −2 in a 0.5 M Na 2 CO 3 (pH = 11.2) electrolyte to understand the micro-arc oxidation (MAO) process. Different oxidation stages were investigated by analysing the voltage–time responses and coating morphology.

Micro Arc Oxidation Coating Parameter-Property Relationship
Materials Performance, 2021Micro arc oxidation coatings were produced on AA7075 (UNS A97075) substrates using various process parameters. The study aimed to improve the surface characteristics of the alloy. Thickness, hardness, and roughness measurements characterized the coatings. It was revealed that the coating thickness was directly related to the coating roughness.

Bioactivity and osteoblast response of the micro‐arc oxidized zirconia films
Journal of Biomedical Materials Research Part A, 2008AbstractZirconia films containing Ca and P were prepared by micro‐arc oxidation (MAO) of zirconium. The microstructure, in vitro bioactivity, and primary osteoblast response of the films were investigated as a function of the applied voltages in the range of 400–500 V.
