Definitions

  • the invention relates to a method for coating the outer surface of a cylinder liner according to the preamble of claim 1.
  • the object of the invention is to avoid this disadvantage of the prior art and also to provide a simple and inexpensive coating process.
  • a cylinder liner which consists of an iron-based material that may be alloyed or unalloyed.
  • the cylinder liner is made of gray cast iron, which may contain either lamellar graphite, vermicular graphite or nodular graphite.
  • the gray cast iron can in this case have a ferritic-pearlitic, a pearlitic, a bainitic or an austenitic basic structure.
  • the outer surface of the cylinder liner may be smooth. But it can also have all other surface finishes to a flat Raugussober Structure.
  • the outer surface, the front side and the inner surface of the cylinder liner can be pre-machined by turning.
  • all common casting methods such as the die casting method, die casting method, gravity casting method or low pressure casting method can be used.
  • the cylinder crankcase is made of one of the common light metal materials, both aluminum-based castings such as EN AC-AISiI OMg (Fe), EN AC-AISiI OMg (Cu), EN AC-AISi9Cu3 (Fe), EN AC- AISiI 2 (Cu), as well as magnesium-based, such as EN MC-MgAI9Zn1 (A), EN MC-MgY4RE3Zr eligible.
  • aluminum-based castings such as EN AC-AISiI OMg (Fe), EN AC-AISiI OMg (Cu), EN AC-AISi9Cu3 (Fe), EN AC- AISiI 2 (Cu)
  • magnesium-based such as EN MC-MgAI9Zn1 (A), EN MC-MgY4RE3Zr eligible.
  • the outer surface of the cylinder liner is coated by dipping. In preparation for this, it is necessary to clean the outer surface of dirt and oxides and then roughen. Suitable methods for this are brushing and / or blasting. For example, coarse corundum to the beam, that is, crystalline Al 2 O are used. 3
  • the outer surface of the cylinder liner is pickled and / or coated with a flux, which is zinc chloride-aluminum chloride double salt or salmiacite (ammonium chloride) is suitable. This is to remove oxides from the outer surface of the cylinder liner to promote the alloying of a metal layer described below.
  • a flux which is zinc chloride-aluminum chloride double salt or salmiacite (ammonium chloride) is suitable. This is to remove oxides from the outer surface of the cylinder liner to promote the alloying of a metal layer described below.
  • the subsequent dipping process for coating the outer surface of the cylinder liner takes place in a zinc-aluminum-copper melt with 3% to 12% copper and 2% to 8% aluminum, the remainder of the melt being zinc.
  • up to 1% magnesium may be added to the melt.
  • the cylinder liner is so far submerged in the melt until a small, over the entire axial length of the cylinder liner continuous segment of the outer surface but not the inner surface of the cylinder liner is wetted by the melt.
  • the cylinder liner is then rotated about its longitudinal axis, wherein the melt is set by ultrasound in a high-frequency movement. This promotes alloying between the cylinder liner alloy and the zinc base alloy of the melt to form a layered intermetallic and mixed crystal layer system that provides metallic bonding of the cylinder liner with the surrounding metal layer.
  • the metal layer has reached a thickness of 100 microns to 300 microns, and the cylinder liner is removed from the melt.
  • the cylinder liner is then mounted horizontally in a holder, wherein excess melt drips and solidifies the applied metal layer.
  • the copper component of the alloy has the advantage that an oxide film that may form during coating does not become too dense, so that it peels off easily when poured.
  • the liquidus temperature of the melt is between 440 0 C and 52O 0 C, which causes the metal layer is melted during casting of the cylinder crankcase of its Umgussmaterial, whereby the metallic bond between the Zylinderiaufbuchse and the Umgussmaterial the cylinder crankcase is ensured. If the gravity casting method is used for this, it is necessary to heat the coated cylinder liners to 300 ° C to 400 ° C. This is omitted in the application of the die-casting process for the production of the cylinder crankcase.
