For anodised steel components, hard anodising, like that from Poeton is a method that is achieved by passing a high voltage current through an anodized aluminum oxide and then cooling it down. Anodized aluminum oxide is formed when an aluminum plate with an electric field that is stretched is placed between two charged conductors with opposite polarity and anodized aluminum comes out. The thickness of this plate depends on the thickness of the aluminum plate and its electrical charge. When a current passes through it, the plate becomes metallic and hard as a sheet and becomes a sort of bead. This hard bead is then coated with a thin layer of aluminum oxide.
Offer hard anodising with a 10 % Sulphuric Acid mixture in -15 C to -40 C. The anodizing process: Hard anodizing is the creation of thin layers of aluminum oxide on the surface of aluminum, which is electrochemically created under controlled conditions in order to give thin protective coatings on aluminum components. This coating can be applied at the anodisation stage itself, where the anodizing takes place in the case of thin layers of aluminum oxide on thin aluminium components. These anodized components can have a hard wearing finish by rubbing them onto a hard wearing steel or perhaps other metal.
The types of metals that can be coated with this coating are also many. There are also various anodisations that can be utilised for this purpose. The most common one used is aluminium oxide and nickel-zirconium. When you’re dealing with aluminium oxide anodised component coatings you’ll often find this coating referred to as ‘anodised coating’.
