Abstract
The invention relates to an iron having a metal soleplate, which is provided with an anti-friction layer containing an inorganic polymer. To improve the scratch resistance of the anti-friction layer, a hard intermediate layer is provided between the predominantly aluminum part of the soleplate facing the anti-friction layer and the anti-friction layer. This intermediate layer is preferably composed of aluminum oxide which is provided by means of an electrochemical treatment. The use of polymerized alkyl trialkoxysilane, in particular methyl trimethoxysilane, in the anti-friction layer makes it possible to obtain layers which are thicker and hence more scratch-resistant. In such layers, oxidic nano-particles and inorganic color pigments may be incorporated, which cause a further increase of the scratch resistance.
