Abstract

A method for treating sheet metal is disclosed. An amorphous mass containing an alloying element is applied onto a first area of a surface of the metal sheet. A second area of the surface is kept free of the amorphous mass. The amorphous mass and at least the first area of the metal sheet are heated in order to alloy the alloying element into the first area of the metal sheet while the second area remains unalloyed.
