Porous anodic alumina can be obtained, in addition to conventional methods such as potentiostatic and galvanostatic, or by pulsed method. Among these are the methods of discontinuous pulse, hybrid pulse and polarized pulse ...

Titanium and some of its alloys exhibit excellent anti-corrosive and biocompatibility properties due to rapid formation of a passive film on their surfaces when exposed to the atmosphere. However, such materials present ...

Al-Cu alloy is largely employed in mechanical and aircraft industries. Usually aluminum and aluminum alloys are submitted to an electrochemical process called anodizing that consists on growing an oxide film on their ...

The purpose of this work was to find a heat treatment process to Al-6.75% Si alloy that makes the dispersion of Si element in order to overcome the difficulties in the anodizing process. Samples were put in an oven at 540°C ...

Background: Several studies proved that anodic oxidation improves osseointegration. This study aimed to optimize osseointegration through anodization in dental implants, obtaining anatase phase and controlled nanotopography. ...
