Patent ID: 8029907

Claim:
A material including a barrier-layer-forming metal, the surface of which is provided with a wear-resistant layer, the material being obtained by a method comprising the following steps: using laser treatment; exposing a material surface to a laser irradiation in the presence of an atmosphere containing oxygen in such a way that a first layer of the material surface reacts with the oxygen to form an oxide of the metal constituting the material; and remelting a second layer of the material lying under said first layer, without reacting with the oxygen, wherein the first layer is an aluminum oxide layer (Al 2 O 3 layer) and comprises at least 60% corundum (a-Al 2 O 3 ) and wherein, in the case of silicon-containing aluminum alloys as the base material that is the material, the first layer also contains up to 10% silicon dioxide (SiO 2 ) in the form of mullite.
