“Every metal, with the exception of gold and platinum, when exposed to the atmosphere undergoes a process of corrosion that leads to the build up of a thin layer on its surface, made of the oxides and hydroxides coming from the reaction of the metal itself with the aqueous vapour present in air. The electrochemical process of anodic oxidation allows the obtaining of an oxide layer which is much thicker and denser than that formed naturally in the atmosphere, thus gaining in hardness, corrosion resistance, dielectric behavior, and a series of functional and aesthetic properties. In particular, the so generated oxide will have determined characteristics, such as thickness, color, density, homogeneity and insulating properties, as a function of the process parameters imposed.”
