Definitions
- the invention relates to a method for producing a cast component and a cylinder liner and a cylinder block containing such a cylinder liner for an internal combustion engine. Furthermore, the invention relates to a piston ring carrier and such a piston ring carrier containing piston for an internal combustion engine.
- Cylinder blocks of modern internal combustion engines are usually produced in a casting process. Since the material used for the cylinder block - usually aluminum or iron, but also suitable magnesium-aluminum composite materials - which is not required for a friction and thus possible wear-free movement of a piston in the cylinder required tribological requirements can not be met in the cylinders so-called cylinder liners used. These have the required tribological properties and thus ensure a largely wear-free long-term operation of the piston in the cylinder block; often such cylinder liners are provided with a roughened, grooved or machined in a similar manner lateral surface. Alternatively, the prior art also teaches the application of an aluminum spray layer on the lateral surface of the cylinder liner. In both cases, the casting of the cylinder liner with an aluminum alloy, which is likewise known from the prior art, can produce a particularly positive connection of the cylinder liner with the cylinder block.
- piston rings usually made of steel used, which can be inserted into a provided on a lateral surface of the piston circumferential groove to produce said sealing effect.
- piston ring carriers are used in conventional pistons, which are encapsulated in a casting process with the actual piston.
- US 4,273,835 describes the manufacture of a cylinder block with a cylinder liner inserted into the cylinder of the cylinder block. Between cylinder liner and cylinder block a silicone resin layer is provided for sealing a water jacket.
- JP 2010-156003 A describes the coating of a cast iron workpiece with an adapter layer containing carbon, manganese, silicon, sulfur and phosphorus.
- the adapter layer increases the adhesion of an aluminum alloy applied to the workpiece.
- the present invention therefore deals with the problem of providing an improved embodiment of a method for producing a cast component and for an insert, which no longer has the disadvantages mentioned above.
- the basic idea of the invention is accordingly to coat the outer surface of an insert in the course of the production process, namely by means of a layer of silicon oxide referred to below as an adapter layer.
- Said adapter layer leads to an improved wetting behavior of the aluminum alloy on the adapter layer during casting over with an aluminum alloy-in particular using the aluminum die-casting presented at the beginning after its introduction into a suitable casting mold.
- Corresponding experimental studies have shown that this only applies in the case the aluminum alloy is provided with a magnesium content of at least 0.3% by weight, preferably of at least 0.5% by weight.
- a particularly positive connection results in the use of the adapter layer according to the invention not only in the so-called.
- Aluminum die-casting process but also in the low-pressure or gravity casting.
- the quality of the positive engagement of the insert with the cast component achievable with the use of the aluminum die-casting method can also be achieved by means of low-pressure or gravity casting techniques.
- step b) of the method according to the invention can comprise the following two sub-steps b1) and b2):
- Silicone resin is commercially available in large quantities in liquid form and therefore inexpensive. In addition, it can be easily on the lateral surface Apply the cylinder liner before inserting it into the cylinder block for potting.
- the conversion of the organic silicone resin in silicon oxide is also very simple: For this purpose, it is sufficient to heat the coated silicone resin insert component - for example, to a temperature of 400 ° C or more - and cure in this way, the silicone resin to silica.
- the hardened silicon oxide can react with the magnesium contained in the aluminum alloy in the region of the interface to the aluminum alloy according to the reaction equation SiO 2 + 2 Mg -> 2 MgO + Si, whereby the wetting of the surface can be decisively improved.
- water glass includes all water-soluble sodium, potassium and silicon silicates solidified from a melt. These have glassy, so amorphous material properties.
- the adapter layer loses its water content, so that a substantially anhydrous, polymerized inorganic silicate is formed.
- the hardened silica in the region of the aluminum alloy interface according to the reaction equation SiO 2 + 2 Mg -> 2 MgO + Si can react with the magnesium contained in the aluminum alloy, resulting in improved surface wetting.
- the water glass comprises Na 2 O 3 Si, ie sodium silicate.
- the invention also relates to a cylinder liner with a jacket surface having a lateral surface, wherein the lateral surface of the female body is coated with an adapter layer of silicon oxide.
- an adapter layer also expressly includes the above-described MgO or Si obtained by reaction with SiO 2 with Mg in the transition region of the adapter layer to the aluminum alloy.
- the invention further relates to a cylinder block with such a cylinder liner, as well as with an aluminum alloy surrounding the adapter layer, which completes the cylinder liner to the cylinder block.
- the invention further provides a piston ring carrier having a shell surface having a ring body, wherein the lateral surface of the ring body is coated with an adapter layer of silicon oxide.
- the invention finally relates to a piston with such a piston ring carrier, as well as with an aluminum alloy surrounding the adapter layer, which completes the piston ring carrier to the piston.
- FIG. 1 shows a silica coated cylinder liner prior to insertion into a mold for producing a cylinder block
- FIG. 2 shows a cylinder liner, cast in an aluminum alloy casting mold, which forms a cylinder block together with the aluminum alloy
- FIG. 3 is an encapsulated with an aluminum alloy ring carrier, which forms a piston together with the aluminum alloy.
- FIGS. 1 and 2 each illustrate, in a roughly schematic longitudinal section, the method according to the invention for producing a cast component 6 in the form of a cylinder block.

- the socket body 2 may be sleeve-like as shown in FIG. Before the socket body 2 is introduced into a casting mold (not shown in FIG. 1), its lateral surface 3 is coated with a layer of silicon oxide, hereinafter referred to as "adapter layer" 4.
- a silicone resin is applied to the areas of the lateral surface 3 to be cast.
- the silicone resin is cured by heating the female body 2 to silicon oxide.
- the socket body 2 can be heated to a temperature of 400 ° C. or more, for example by means of a suitable oven.
- a small layer thickness promotes a rapid curing process, which has an advantageous effect on the industrial production of the cylinder liner in large quantities.
- the silicone resin applied to the lateral surface 3 has a layer thickness of from 5 to 10 ⁇ before curing to form silica.
- the silicone resin can be diluted prior to application to the lateral surface 3 by means of a solvent.
