The Electrical and Mechanical Properties of Porous Anodic 6061-T6 Aluminum Alloy Oxide Film

الملخص EN

The properties of the growth of the 6061-T6 aluminum alloy oxide were studied using sulfuric acid anodization.

The parameters for the manufacturing process include electrolyte categories, electrolyte concentration, and operating voltages.

The results showed that the aluminum oxides obtained by anodization process are mainly amorphous structure and the anodic current density is an important factor affecting the rate of response for oxygen and aluminum ions in barrier.

In this experiment, polish process is very important to stable the anodic aluminum oxide film and then it will get the better properties of anodic film.

Besides, when using sulfuric acid as the electrolyte, the increase of anodic voltage also increases the rate of reaction which increases the mechanical and electrical properties of anodic oxide film, but too large applied anodic voltage will reduce the mechanical and electrical properties of film because of the crack of the anodic oxide film.
