    摘要： Disclosed is a method for producing wear-resistant layers on materials of barrier-layer-forming metals, such as aluminum, magnesium and titanium and their alloys and mixtures, preferably aluminum or its alloys, by means of laser treatment, the material surface being exposed to a laser irradiation in the presence of an atmosphere containing oxygen in such a way that the upper or outer layer of the material surface reacts with the oxygen to form an oxide of the metal constituting the material, preferably aluminum oxide, and the layer of the material lying under that is remelted without reacting with the atmosphere containing oxygen. This results in a multilayer structure with excellent wear-resistant properties, including excellent corrosion resistance, excellent abrasion resistance and extreme hardness that does not exhibit any brittleness as a result of the hardness gradient within the layer structure.
