Definitions

  • the invention relates to powders for producing hard materials with short reaction times, in particular for filling hollow wires for arc spraying.
  • wear-resistant protective layers can be produced by arc spraying cored wires (German Patent No. 2002472, European Patent No. 0118307).
  • the invention has for its object to produce hard materials with the short reaction times available during arc spraying (from the melting point until the particles hit the substrate).
  • the powder used for filling the hollow wires by spray drying or agglomeration of powder Migen metallic and / or non-metallic starting materials is produced using organic or inorganic binders, so that high proportions of hard materials can form on the flight path of the spray particles - from the melting point to the substrate surface.
  • the distance (reaction path) between the powdery starting materials (reaction partners) is significantly reduced compared to a loose powder mixture and the reaction yield is increased.
  • some of the powdery starting materials consist of exothermic metals such as Al, Ni, Ti, Cr, Mo, V, Zr, Ta.
  • Another part of the starting powder consists of metallic and non-metallic hard materials such as Cr3C2, SiC, TiB2, CrB2, B4C, TiC, VC, TiN, Si3N4, WC, which are converted to other hard materials during the particle flight.
  • some of the powdery starting materials can be made from oxides which react strongly exothermically with the metals Al, Ni, Ti, Cr, Mo, V, Zr, Ta, such as Cr2O3, ZrO2, TiO2, CoO, Al2O3 and CeO2 exist.
  • part of the powder can also be composed of inert powder-like master alloys based on iron and non-iron such as FeCr, FeCrC, FeMo, CoB, MoNi, FeMn, FeW, FeNb, NiB, FeB, NbCr and / or carbon.
  • the advantages achieved by the invention are, in particular, that hard materials can be produced in a short time, starting from inexpensive starting powder.
  • This makes it possible, for example, when using these powders produced by spray drying or agglomeration to fill hollow wires for arc spraying, to produce wear-resistant layers with a high proportion of hard material.
  • these powders produced by spray drying or agglomeration to fill hollow wires for arc spraying, to produce wear-resistant layers with a high proportion of hard material.
  • the layers produced in this way are more homogeneous and self-adhesive than conventional layers. The spraying of expensive primer layers is therefore not necessary.
  • FIG. 1 shows, by way of example, the top view of a simple powder which is composed for the filling of hollow wires for arc spraying and is produced by spray drying or agglomeration.
  • the chrome and silicon carbide particles associated with an alcohol are superficially coated with aluminum and nickel particles. Due to the high melting temperature during arc spraying and the short reaction paths resulting from the bonding, the chromium and silicon carbide particles react at the interfaces according to the following equation: 1) aCr + bSiC ⁇ cSiC + dCr x C y + eSi to chrome carbide. Due to the strong exothermic character and the parallel reaction between nickel 1 and aluminum 2: 2) Ni + Al ⁇ NiAl the temperature of the spray particles is increased and the cooling of the particles on the flight path is counteracted by radiation and convection, ie the course of the reaction 1) is accelerated and supported.
  • reaction of aluminum with excess silicon from reaction 1) results in a wear-resistant and corrosion-resistant matrix component made of AlSi in accordance with the following reaction: 3) Al + Si ⁇ AlSi generated.
  • FIG. 2 shows a plan view of a further example of a simple powder which is composed for the filling of hollow wires for arc spraying and is produced by spray drying or agglomeration.
  • FIG. 3 shows a top view of another example of a simple powder particle which is composed for filling hollow wires for arc spraying and is produced by spray drying or agglomeration.
  • the ferrochrome and graphite particles associated with water glass are coated on the surface with aluminum and chromium oxide particles.
  • the ferrochrome particles react with the graphite particles according to the following reaction: 6) aFeCr + bC ⁇ cCr x C y + dFe to chrome carbide.
  • aFeCr + bC ⁇ cCr x C y + dFe to chrome carbide As a result of the exothermic reaction between aluminum 4 and chromium oxide 5: 7) aAl + bCr2O3 ⁇ cAl2O3 + dCr reaction 6) is forced in the same way as in the first example.
