The anodic oxidation or aluminium anodization is a non-spontaneous electrochemical process that modifies
the mechanical characteristics of an artefact through the superficial transformation
of aluminium in Al2O3 aluminium oxide (alumina or corundum).
In general, thermic treatment includes a series of heating operation,
single or consecutives always operating under the same fusion temperature,
followed by a certain resting period and a following cooling process of different length.
