Anodising (anodizing) covers a range of techniques, with different electrolytes. But each is an electrolytic process, primarily for aluminium alloys, transforming the surface layer into a hard aluminium oxide. Generally, the part is made the anode in an acid bath, with lead cathodes, and a closely controlled DC voltage is applied across them. (Apticote 3000 uses an AC voltage; see below)
The Apticote 300 process is a unique approach to precision aluminium hard anodising (or hard anodizing). Poeton provide a level of quality control, combined with high throughput and low turn-round times, that is unmatched by our competitors.
As well as Hard Anodising and Anodic Polymer Composites. Poeton offer Chromic Acid Anodising and Sulphuric Acid Anodising, mainly for Aerospace and Defence parts. Chromic acid anodising on aluminium is typically 1 to 2µ thick, often used as a pre-treatment prior to painting, as well as for some corrosion protection. Sulphuric acid anodising produces layers 10 to 15µ for corrosion protection of aluminium and dying in a wide range of colours.
The ultimate replacement for Chromic Acid Anodising
Poeton Apticote 300TSA (Tartaric Sulphuring Anodising) provides superb corrosion protection and paint bonding properties for a wide range of aluminium alloys. Apticote 300TSA is now becoming standard for the Aerospace and Defence industries, replacing the environmentally unacceptable Chromic Acid Anodising for aluminium.
The APTICOTE 350 range of hard anodised composite coatings make aluminium surfaces as hard as steel. By combining the hardness of aluminium oxide with the lubrication, wear resistance and corrosion protection of fluorocarbon polymers, they impart to the aluminium surface previously unattainable properties.
Apticote 355 and 356 are the latest technology breakthrough from Poeton Industries, whereby hard anodic films can now offer unsurpassed levels of corrosion resistance for aluminium alloys, levels that far exceed those achieved with standard hard anodic films.
Apticote Keronite 3000 is a unique electro-ceramic process that transforms the surface of light-weight alloys (aluminium, magnesium and titanium) to provide thick, hard, tough and wear resistant layers. It is based on a liquid electrolyte to provide surface properties that are unmatched by any conventional conversion or anodising approach.
