Definitions

  • the invention relates to a method for producing wear protection layers on surfaces of components made of titanium or titanium-based alloys, by applying a nickel layer adhering to the component surface, subsequent heat treatment to form a diffusion layer and subsequent removal of the residual Ni layer.
  • the object of the present invention is to provide a method with which a protective coating layer can be produced, which has a particularly high resistance to friction and erosion and which maintains its intimate connection with the titanium material even under extreme operating conditions.
  • the object is achieved in that for the formation of two defined diffusion layers of Ti 2 Ni and TiNi 3 between the titanium base material on the one hand and the nickel layer on the other hand, before the nickel layer is applied, the surface is activated in a bath of chromic acid, hydrofluoric acid and hexafluorosilicic acid and the heat treatment takes place in air or in vacuum at a temperature of 400-600 ° C.
  • the components are protected from excessive thermal stresses and therefore from the risk of warping due to the relatively low diffusion temperature.
  • Another advantage of the method according to the invention is that the diffusion layers form very uniformly over the entire surface of the titanium component, both with regard to the thickness distribution and with regard to the composition. To this extent, the method according to the invention is suitable for series production, since there is a high degree of reproducibility.
  • the activation of the component surface is preceded by an etching of the surface, preferably in a nitric acid-hydrofluoric acid solution.
  • the nickel layer is preferably chemically deposited by reacting the titanium surface with a bath of nickel salt, a complexing agent and a chemically reductive agent, for example hypophosphite.
  • the TiNi 3 layer should also be removed in addition to the residual nickel layer, so that the Ti 2 Ni layer remains as the top layer.
  • the hardness of this layer is still remarkable and is about 600 HV; however, it is more ductile than the TiNi 3 layer.
  • both diffusion zones TiNi 3 and Ti 2 Ni are formed in a layer thickness of approx. 4 pm each.
  • the layer sequence from outside to inside is: nickel, TiNi 3 , Ti 2 Ni, titanium or titanium material.
  • the hardness of the diffusion produced in this way sion layers differ significantly from the starting materials nickel on the one hand and titanium on the other hand, which results from the following hardness table:
  • the nickel cover layer or the nickel cover layer and the TiNi 3 layer are removed chemically by the action of HN0 3 or by a nitroaromatic solution (cyanide) at temperatures between 10 and 60 ° C.
  • the stripping times are between 15 minutes and 2 hours, depending on the remaining layer thickness of the nickel, the concentration of the stripping bath and the bath temperature.
