2009年3月6日 · The color is caused by the combination of the material composition and the composition of the anodizing bath. The main constituent of the anodizing bath is oxalic acid but there are some other elements involved as well. The process is called "opalising" because the coating is not transparent (looks like enamel).

Opalising is a special form of anodising. The aluminium oxide layer, which is obtained electrochemically, is partially formed on the base material but also partially extends into the base material. The low growth rate and low layer thickness make this treatment layer ideal for achieving dimensionally stable application.

Opalising is a special type of anodising. The result is a hard, wear-resistant, exceptionally smooth layer with a distinctive decorative character (opal colour). The layer thickness varies – depending on the base material – from 5 to 20 μm. The hardness is 500 to 700 MHV. The aluminium layer

阳极氧化 （Anodizing）： 阳极氧化是一种通过在铝合金表面形成氧化层来增强其硬度和耐腐蚀性的过程。 这一层 氧化膜 通常也提供了对染色的选项，以改变铝合金的外观。

2018年1月1日 · Anodizing for protective and decorative purposes is the most common method of superficial oxidation processes and is carried out through anodic oxidation. The oxide films, resulted from...

2024年11月8日 · Anodizing is a surface treatment method that produces a thin film with a thickness ranging from 0.5 to 150 µm. The thin film enhances the corrosion resistance, wear resistance, strength, and surface hardness of non-ferrous materials like aluminum. The anodized layer or oxide layer is formed electrolytically.

Chapters are devoted to the properties, alloys, and finishes of Al; mechanical treatments and finishes; electrolytic and chemical polishing; chemical cleaning and etching; chemical conversion coatings; theoretical models of anodizing; decorative and protective anodizing; and anodizing in …

Since the polished surface is vulnerable to scratches and corrosion, it is usually combined with anodising or transparent organic finishing. The process is used for producing reflectors and decorative components. The best result is obtained by …

2023年7月30日 · Anodizing not only enhances aluminum’s corrosion resistance and aesthetic appeal but also increases its surface hardness. This article will guide you through the science behind anodizing aluminum alloys, the various surface treatment methods involved, and how they impact the final product’s durability and appearance.
