- a cylinder liner consisting of a molybdenum and an outer layer Layer consists of an aluminum alloy, which at its Outside is profiled. Both layers are going through thermal spraying formed on a rotating mandrel.
- molybdenum an anti-adhesive agent, a mandrel with a hard chrome layer and the like the adhesion of the overlay on the mandrel is reduced so far, that the bushings can be removed from the mandrel.
- the cylinder crankcase is to DE 196 34 504 A 1 by irradiating the surface of the Cylinder liner with sharp-edged particles one Roughness of 30-60 ⁇ m in the form of pyramid-like Dents made.
- the oxide skin is on an aluminum body, which is in a Cast aluminum material is to be poured, the Connection to the casting material is prevented, according to DE 197 45 725 A1 through the oxide skin on the sprue Thermal spraying mechanically destroyed, the hereby distributed oxide particles in the sprayed layer become. In addition, they do not protrude completely on impact melted spray material particles from the Sprayed layer, whereby the connection with the casting material is improved.
- a spray material is a nickel or Molybdenum alloy used.
- a method for producing a Cylinder liner known in which as a Shaped mandrel forming a tread Layer, for example of a molybdenum alloy, and on the tread layer, a cover layer, for example from an aluminum alloy, by a thermal Spraying be applied.

- the mandrel So that the jacks fit accurately when pouring on the sleeves can be placed, the mandrel has the same Dimensions like the quills on. Accordingly, the mandrel with the same cone angle of z. B. 0.5 ° as the sleeves be conical to the Cylinder liner blanks perfectly fitting the sleeves to be able to attach.
- the mandrel may be hollow to him with a medium, such as water, to be able to cool. After this Thermal spraying can then cause the mandrel to cool off the still hot thermal cylinder liner blank shrunk. Also, the spike can be squeezed out be removed from the cylinder liner blank.
- a medium such as water
