Definitions

  • the invention relates to a method for generating of corrosion and wear protection layers on iron-based materials, near the surface Areas enriched with nitrogen, carbon as well as oxygen become.
  • nitride layer on aluminum or aluminum alloys it is from EP-A-0 158 271 known that the surface of the nitriding Material by means of a glow discharge with a Noble gas is activated as activation gas. This activation process serves to do so, by the ion bombardment the surface of the material to be nitrided this material surface of organic components, such as cleaning carbon and oils, so that in the subsequent nitriding process a permanent Connection of the nitriding layer with the aluminum material is possible.
  • the invention is based on the object Process for the production of corrosion and wear protection layers on iron-based materials on the one hand, the aforementioned disadvantages does not have and on the other hand, longer service life of thus treated materials allows.
  • the process is the oxidation in one Temperature range of 480 ° C to 520 ° C performed.
  • the activation of the material surface during the plasma-assisted vacuum method takes place advantageously by the bombardment of the material surface with nitrogen, hydrogen, carbon and oxygen ions.
  • the composition of a gas mixture to r generation the above-mentioned ions in the plasma can be defined and targeted changes in the Nitrocarburier suits formed compound layer be brought about, which in turn also on the subsequent oxidation step.
  • the normal pressure gas nitrocarburizing process and oxidizing and the plasma assisted vacuum process are executable in the same plant.
  • the iron base substances to be treated are first to the treatment temperature of about Heated to 500 ° C to 590 ° C and then in a Ammonia-nitrogen-carbon dioxide atmosphere the Nitrocarburierprozeß subjected to the enrichment from nitrogen and carbon to one from iron carbonitrides existing connection layer leads. After taking place under normal pressure Nitrocarburiervon the workpiece is at the temperature led the oxidation treatment. It can as well a cooling of the workpiece to room temperature respectively. For the following plasma-assisted Ion bombardment of the workpiece surface is the process room is evacuated. Likewise, besides this Evacuation with previous cooling of the workpiece to room temperature a simultaneous warming of the workpiece to the temperature of the oxidation treatment necessary.
  • the material is switched as a cathode, while, for example, the plant wall as Anode is connected.
  • the bonding layer formed so changed by heating, implantation and sputtering, that in the subsequent oxidation step a closed and uniform oxide layer in and on can form the bonding layer. Training the uniform oxide layer is thereby supported, that the plasma is during the activation process around the entire surface of the material formed.
  • the system with Nitrogen as inert gas flooded to normal pressure and the Material back to its treatment temperature of heated to about 480 ° C to 520 ° C.
  • water vapor for the oxidation process for generating a nitrogen-water vapor mixture directed to the plant. After completion of the oxidation process becomes the thus treated Material cooled under further nitrogen supply.
