Definitions

  • the invention relates to a method for producing a metallic component, in which a base body provided with an aluminum coating and the coated base body is encapsulated with an aluminum alloy, and a component having a base body, on the outer surface of an aluminum layer is formed, wherein the base body with a Aluminum alloy is cast.
  • the coatings of the einzug manenden base body serve a better adhesion of the body to the surrounding casting.
  • cylinder liners which form the running surfaces for the cylinder or pour slide bearings in the cylinder crankcase made of aluminum.
  • the cylinder liners are made, for example, from a high strength iron-based alloy, such as lamellar gray cast iron.
  • the application of the layers can be done for example by Alfinieren or thermal spraying.
  • This object is achieved by a method in which the aluminum coating is applied galvanically to the body, and by such a manufactured component. This ensures that the deposited on the body aluminum coating with the aluminum casting alloy enters into a strong metallurgical bond and a good bond of the aluminum coating is made to the body. This is achieved in addition to the stronger bond during plating by electroplating also characterized in that undercut structures can be evenly and completely coated, for example, body with Verklamm réelles Designen or Raugussbuchsen, which are difficult to access by spraying.
  • the aluminum coating may advantageously be an aluminum-based alloy coating. This allows the reduction of Melting point of the aluminum layer during subsequent Umge manen, so that the bond is improved again.
  • the aluminum coating with a thickness in the range from 5 to 100 ⁇ m, preferably from 10 to 60 ⁇ m and in particular from 20 to 40 ⁇ m.
  • a thickness in the range from 5 to 100 ⁇ m, preferably from 10 to 60 ⁇ m and in particular from 20 to 40 ⁇ m.
  • Such layer thicknesses have proven in experiments to be sufficient to improve the bond both to Umgusstechnikstoff and to the body.
  • the coated base body is recast with an aluminum-based alloy.
  • an AlSi9CU3 alloy can be used.
  • the base body can be cleaned before the galvanic application of the aluminum coating on the body. This can be done mechanically, in particular by blasting and / or chemically, in particular by applying a flux. As a result, the adhesion of the coating to the base body is additionally improved.
  • undercut structures can be evenly and completely coated, for example, base bodies with interlocking structures or bushings.
  • the base body is made of an iron-based alloy, in particular of lamellar gray cast iron (GGL).
  • GGL lamellar gray cast iron
  • a nickel coating is applied galvanically to the base body prior to the galvanic application of the aluminum coating.
  • the nickel coating with a thickness of> 5 microns, in particular in the range between 1 to 2 microns are applied to the body. It has been found that the bonding of nickel, for example, to gray cast iron is more resistant than the bond between aluminum and gray cast iron. In addition, the binding is also between the aluminum coating and the nickel layer more resistant and better, so that overall the strength of the connection to the socket is increased.
  • the surface of the base body has a clamping structure with a strong profiling or undercuts.
  • the component is a cylinder crankcase or a cylinder crankcase lower part, which is also referred to as a bearing traverse or Bedplate.
  • the inventive method can be used particularly advantageous.
  • the main body is a cylinder liner.
  • a micrograph of a component produced by the method according to the invention is shown in the figure.
  • the illustrated component 1 consists of a base body 2 in the form of a cast iron cylinder liner, which was first cleaned chemically by means of a flux. On the cleaned surface then a nickel layer 3 was applied galvanically. The thickness of this nickel layer 3 is about 5 microns. In turn, an aluminum layer 4 in a thickness of about 25 ⁇ m was applied to this nickel layer 3 galvanically in a galvanic bath. The thus prepared cylinder liner 2 was then encapsulated with an aluminum-silicon alloy 5 of AlSi9CU3 in the die-casting process for producing a cylinder crankcase 1.
