The anodic oxidation (or anodization) process is an electrochemical process by which, through the application of a potential difference, the surface of a metal object (mainly aluminum) is transformed into a protective oxide layer.<\/p>\n
Unlike gilding, the oxygen that reacts with the object is not deposited from the outside, but combines with the base metal starting from the electrolytic solution, creating a layer that is an integral part of the surface of the artifact itself.<\/p>\n
However, before the oxide layer can form, the substrate must be prepared through a specific process of chemical cleaning, degreasing and satin finishing, which are essential to ensure the uniformity of the treatment.<\/p>\n
Anodic oxidation serves not only to give the object aesthetic characteristics (thanks to the possibility of coloring the porous layer) but also functional characteristics such as: corrosion resistance, surface hardness and electrical insulation.<\/p>\n","protected":false},"featured_media":3511,"template":"","meta":{"_acf_changed":false},"divisioni":[16],"class_list":["post-3856","processi","type-processi","status-publish","has-post-thumbnail","hentry","divisioni-galvanica"],"acf":[],"yoast_head":"\n
