6061 Aluminum Surface Treatment by High Quality Coloring Anodic Film

Abstract

Electrochemical techniques can be used in the various fields, such as anodization, deposition, etching, polishing, pitting, and corrosion applications. In this paper, we focus on the high quality coloring anodic film fabrication. In the prior technologies, anodization generally has the main purpose of surface decoration or corrosion resistance. However, in the high technologies, the characteristics of film thickness, anti-voltage value, surface roughness, surface color and hardness of the anodic film have been strict requirements. The key parameters of anodization such as, electrolyte composition, current-voltage curve pattern, temperature, current density, time, final voltage, efficiency, and electricity affect the quality of anodic film. In order to make a high quality anodic film, this paper provided a detail anodization process and discussed the quality of anodic film.

Facile Route to Effective Antimicrobial Aluminum Oxide Layer Realized by Co-Deposition with Silver Nitrate

“…However, its application range has been restricted due to corrosion phenomena [9,10]. Thus, aluminum components are often subjected to a surface anodizing process [11][12][13][14][15][16], to improve their protective properties [17,18], chemical resistance [19,20] and also their aesthetic features [21,22]. As a consequence of the health emergency, even the anodized aluminum surfaces must be modified and made naturally antibacterial, to avoid the spread of the virus without the need for continuous disinfection of public spaces.…”

Surface-Initiated Polymerizations Mediated by Novel Germanium-Based Photoinitiators

“…In most cases, surface modification aims to create a specific functionality that is able to interact with other media, materials, or components. Those functionalities include, for example, control of adhesion, wettability, , adsorption properties, and anticorrosive or antifouling behavior of surfaces. Considering this wide range of applications, great efforts have been made in the biomedical field.…”
