Abstract

1. A component made of aluminium or an aluminium alloy which has on its surface a hard oxide coating with a thickness of between 25 and 250 microns, the hard oxide coating being treated with an electrolyte which contains metal salts and preserved with a water-repellent agent, characterised in that the hard oxide layer has a pore volume of between 5 and 15%, the hard oxide layer is substantially free from microcracks, metal salts are absorbed into the hard oxide layer and hydrolysed to form hydroxides and the hard oxide layer has a surface roughness of between 0.8 and 1 micron.
