Abstract

This invention refers to a procedure for anodising aluminium or aluminium alloys in which an aluminium or an aluminium alloy part is submerged an in an aqueous solution at a temperature between 0°C and 140°C, preferably between 0°C and 130°C, in which said solution includes:
- sulphuric acid,
- tartaric acid, and
- at least one inorganic salt of an element selected between at least one transition metal, a lanthanide element, an actinide, and combinations of them,
and applying a controlled potential difference, obtaining layers of aluminium oxide with properties as good as or even better than those obtained through anodising in traditional chromic acid solutions.
