Definitions
- the invention relates to a method for producing a Wear layer in the cylinder raceways of light metal cylinders for internal combustion engines, one of which Metal alloy with a wear layer Layer thickness between 10 and 600 microns on the inside of the Cylinder barrel forming cylinder space is applied
- the present invention is based on the object Specify the procedure of the type mentioned, in which the Connection of a wear layer to the light metal alloy of the cylinder is improved, the wear layer in their properties themselves are not changed.
- This object is achieved according to the invention in a method of the type mentioned in that an electromagnetic alternating field with a frequency between 10 kHz and 5 MHz is radiated onto the wear layer from within the cylinder space for a duration of 1 to 30 seconds and thereby an interface area at the transition Partly melted from the base material of the cylinder to the wear layer with a liquid content of less than 50% and that this creates interfacial diffusion processes.
- the interface area is heated for a very short time above the solidus temperature of the base material, but only partially melted so that the liquid content is below 50%, since otherwise the dimensional accuracy would be feared.
- the conductivity of light alloy cylinder alloys aluminum alloys in particular are usually like this great that the penetration depth of the electromagnetic waves is very small and is only about 1 to 10 microns.
- Within this interface area becomes eddy currents generated, which in turn penetration of the field after the Lenz's rule seek to prevent so the field strength of the penetrating alternating electromagnetic field increasing depth decreases exponentially.
- Through the eddy currents can be a very strong local, essentially on the Limited heating of the light metal alloy be reached through their solidus point.
- the Interface area in the transition between base material and Wear layer is partially melted with a Liquid content of less than 50%. By doing Transitional areas will then find interface diffusion processes due to the increased mobility with increasing temperature of the alloy components.
- the ones described above Processes take place within a very short period, from 1 to 30 Seconds of limited time. They lead to one continuous metallurgical connection of the wear layer to the light alloy of the cylinder.
- the figure shows an overall reference number 2 designated device that as self-employed is considered fundamental to the invention, for generating and Irradiation of an alternating electromagnetic field in a Wear layer or an underlying one Light alloy of a cylinder raceway Cylinder blocks of an internal combustion engine.
- the Device 2 is in the longitudinal direction of the cylinder, ie in the direction of arrow 4, inserted into a cylinder bore.
- the Device comprises a carrier body 6 consisting of a Outer tube 8 and an inner tube 10, the outer tube 8 has a flange-shaped section 11 with which the Device 2 on the head side on the not shown Cylinder block can be placed.
- the outer tube 8 and that Inner tube 10 also provide the electrical coax feed an induction coil 12 in the form of a waveguide 14 with rectangular cross section, which is helical around the Longitudinal axis is provided around.
- a field concentrating means 16 in the form of ferrite cores for high-frequency alternating fields or in shape of sheet metal packages made of nickel alloy for alternating fields up to 50 kHz provided through which the occurrence of eddy currents largely avoided within the induction device shall be.
- the helical waveguide 14 forms at the same time a conduit 18 for a coolant, which in the shown case fed through the inner tube 10 and in Area fed from the lower end into the waveguide 14 becomes.
- the cooling medium flows through the helical Waveguide 14 and leaves the arrangement in the upper area between the inner tube 10 and the outer tube 8 in axial Direction.
- FIG. 2 shows a schematic representation of another preferred arrangement of a device 20 for generating and Irradiation of an alternating electromagnetic field.
- This Arrangement is compared to that described above in advantageously with only a single internally cooled Turn 22 formed, d. H. the coil is in axial Direction as short as possible.
- the winding 22 has in the area its radially outer surface 24 to be treated a pointed geometry. To this A way can be within the surface of the cylinder race circumferential, but extreme in the axial direction short, locally limited heating zone can be achieved.
- This device 20 is then relative in the axial direction 24 moved to the cylinder bore. It has been shown that with this tapered geometry radially the base material outside of the solidus temperature according to the invention increasing interface area kept colder can be. This proves to be advantageous as a result of the Treatment generated warpage of the component to be manufactured in occur to a lesser extent.
- Coil can be used with a field concentrator, it allows a very short in the axial direction 24 To generate heat input distance. In any case, one such arrangement relative to the coated and treating cylinder race moves.
- the Arrangement 2 or 20 in the longitudinal direction 4 in a cylinder bore an internal combustion engine introduced.
- the arrangement 2 remains stationary, while the arrangement 20 opposite the Cylinder track is moved in the axial direction. It will short-term currents of several thousand amperes in the area between 10 kHz and 5 MHz for a period of 1 to 30 Seconds via the coaxial feed into or through the Waveguide 14 generated 1 to 30 seconds.
- This alternating electromagnetic field penetrates the surface a wear layer of a cylinder race and that Base material of the cylinder race and warms you up Interface area in the heterogeneous area one of the Materials (above solidus temperature). This will cause agitation of the interface diffusion processes that arise intimate metallic connection between the metal of the Base material of the cylinder block and the wear layer generated.

Description
Der Grenzflächenbereich wird sehr kurzzeitig über die Solidustemperatur des Grundmaterials erhitzt, jedoch dabei nur teilerschmolzen so dass der Flüssiganteil unter 50 % liegt, da andernfalls eine Beeinträchtigung der Maßhaltigkeit zu befürchten wäre.
Ferner könnte es sich als vorteilhaft erweisen, wenn die Verschleißschicht zuvor auf eine Pinole des Gießwerkzeugs buchsenförmig aufgespritzt würde.
