Definitions

  • the invention relates to a method for producing an oxidic wear protection layer on metallic materials, for. As magnesium, titanium or aluminum.
  • the aluminum material z. B. is a very light material, but its strength and hardness are far inferior to those of iron-based materials.
  • the wear protection to be achieved by anodizing is insufficient, since the layer hardnesses amount to a maximum of approximately 500 HV. For cast or die-cast aluminum-based materials, this value is far from being achieved despite the use of hard anodising.
  • EP 1050606 A1 (Keronite) describes a plasma-chemical process in electrolytes with the aid of which very wear-resistant surfaces on aluminum alloys can be produced.
  • the process is extremely energy-intensive and works at very high voltages.
  • the deposition rate of the oxide layer is very low and is about 1 micron / min.
  • EP 1657326 a plasma-chemical process in electrolytes is described, in which an aluminum or magnesium piston in the annular groove is selectively coated with a wear protection layer.
  • Aluminum nitride is very hard (about 1230 HV), but has the disadvantage that it is very brittle and the ALN layer tends to flake off.
  • the ALN layers are very thin and require long process times to produce. When the ALN layer is exposed to a point load, the so-called “eggshell effect” occurs, ie the ALN layer is pressed in and the wear protection is no longer ensured, which is why the laser treatment process becomes ALN layers on aluminum materials in practice little used.
  • the reaction barrier comprises a reaction of aluminum and oxygen from disassociated water under high temperature and low oxygen concentration produced in a gaseous, water vapor-containing atmosphere ⁇ -Al2O3 layer.
  • titanium migrates through the ⁇ -Al 2 O 3 layer to a gas / reaction barrier interface where it oxidizes to form a Ti 2 O 3 layer.
  • a surface of the Ti 2 O 3 layer is subsequently oxidized to form a TiO 2 layer.
  • a three-layer reaction barrier is formed with a high bond strength, in which the non-connectable ⁇ -Al2O3 and TiO2 layers are separated by the Ti2O3 layer.
  • the three-layer reaction barrier is not suitable for improving the wear resistance of aluminum materials. In addition, it can only be formed on materials containing both titanium and aluminum.
  • US 6,933,053 B2 discloses a method of forming a barrier layer of certain reactive elements on an aluminum-containing substrate.
  • a dry atmosphere of nitrogen and oxygen and a water vapor concentration of less than 750 ppm (parts per million) at a temperature above about 550 ° C. near the surface on which the barrier layer is to be produced is produced.
  • the water vapor in the dry atmosphere reacts with certain reactive elements on the surface of the substrate.
  • the barrier layer comprises an aluminum oxide layer at the boundary between the barrier layer and the substrate. The barrier layer prevents the penetration of oxygen, which improves the oxidation resistance but not the wear resistance of the substrate.
  • No. 6,589,365 B2 discloses applying a hydrogen peroxide solution selectively to a part of the surface of the workpiece to be provided with an oxide layer and directing a light beam through the hydrogen peroxide solution onto the workpiece.
  • the desired oxide layer forms in the area illuminated by the light beam through the hydrogen peroxide solution.
  • a local, selected area of the surface of the workpiece can be specifically provided with an oxide layer.

  • the invention is therefore based on the object to provide a method by which a wear protection layer can be produced on an aluminum material, which has very good crack sensitivity, strength, hardness, wear and corrosion protection properties.
  • a melt layer forms, which reacts with the oxygen and forms a very hard corundum layer.
  • the strongly exothermic reaction in the reaction of metal with oxygen to the metal oxide positively influences the reaction rate, so that corundum or other oxides such as AL oxide or mixed oxides formed from alloying elements form as high-temperature form. It is possible to move the laser during the coating or vice versa the metallic workpiece.
  • the surface of the aluminum workpiece is scanned systematically with the laser beam. In this case, work is carried out in a pure oxygen atmosphere, which is realized by a reaction space with pure oxygen or by nozzles, which directly transport the oxygen in the vicinity of the incident laser beam on the material.
  • the pressure to be set is between atmospheric pressure 0.1 and 100 bar.
  • the method can also be operated selectively, i. H. only selected surface areas of the aluminum material are laser-oxidized.
  • Particularly suitable lasers include a Nd: YAG laser with 532 nm or 1064 nm wavelength.
  • the energy density of the laser is preferably adjusted depending on the corundum layer thickness of 0.2 to 50 J / cm 2 .
  • other lasers can also be used as an energy source. Pulsed variants can also be used here.
  • an ultraviolet, green or, inter alia, infrared laser radiation can be used for the laser oxidation.
  • this Upon exposure of the laser on the aluminum material, this is remelted to a very fine-grained aluminum layer, for example up to 0.1, up to 300 or up to 2000 microns and on this fine-grained aluminum layer then forms the wear protection layer of corundum to a thickness of 300 microns.

Abstract

L'invention concerne un procédé de formation d'une couche de protection contre l'usure sur des matériaux à base d'aluminium, de magnésium, de titane, leurs alliages ou similaires. Des parties de la surface du matériau sont durcies et la couche de protection contre l'usure est formée sur la couche durcie. La couche de protection contre l'usure s'obtient par oxydation au laser dans un gaz qui contient de l'oxygène, sur la couche à grains fins de métal fondu.
