Definitions
- the invention relates to a method for producing a piston of an internal combustion engine, wherein a piston blank made of an aluminum-silicon alloy is poured with the addition of copper fractions and then finished, according to the features of the preamble of claim 1.
- the other possibility for producing a piston, with which the desired complex designs can be achieved is the casting method, wherein for the production of pistons made of light metal materials preferably an aluminum-silicon alloy is used, which is entered as cast melt in a mold, there solidifies, after which a piston blank of the
- Casting mold can be removed and finished. Finishing is usually to be seen in that by machining, such. Turning or milling, the piston blank is made to measure and other elements (such as annular grooves, bolt holes, inlet and outlet openings for a cooling channel in the piston) and the like are introduced. Thereafter, the finished piston is available and can be installed in the internal combustion engine.
- Finishing is usually to be seen in that by machining, such. Turning or milling, the piston blank is made to measure and other elements (such as annular grooves, bolt holes, inlet and outlet openings for a cooling channel in the piston) and the like are introduced. Thereafter, the finished piston is available and can be installed in the internal combustion engine.
- the invention thus relates to a method for producing a piston in which a piston blank made of an aluminum-silicon alloy is cast.
- a piston blank made of an aluminum-silicon alloy is cast.
- copper shares this alloy the strength of the finished piston under consideration of the conditions during its operation in the cylinder chamber of the internal combustion engine are not yet satisfactory.
- a motorized sliding combination of an aluminum-based alloy is known from DE 10 2005 047 037 A1.
- the invention is therefore based on the object to provide an improved method for producing a piston of an internal combustion engine, wherein a piston produced by this method significantly improved
- the copper content amounts to a maximum of 5.5% of the aluminum-silicon alloy and that proportions of titanium, zirconium, chromium or vanadium are added to the aluminum-silicon alloy and the sum of all components (including possible impurities) is 100%.
- the use of such a piston alloy has the advantage that thus high vibration strengths of the finished piston in the cylinder chamber of the internal combustion engine at high temperatures, i. under full load, as well as at medium temperatures, i. at partial load of the internal combustion engine, let achieve.
- Another advantage is the fact that the components of the piston alloy can be assembled easily, which is a key advantage in the mass production of pistons.
- the aluminum-silicon alloy phosphorus is added. This has the advantage that the Kornfeinungs bin is improved and adjusts a better flowability. These properties in particular show their optimum effect in interaction with the other proportions in the piston alloy when the phosphorus content is 40-80 ppm.
- beryllium vanadium is added to the piston alloy. This addition of beryllium vanadium advantageously reduces the formation of oxides, especially on the surface of the piston blank or of the finished piston.
- the cobalt alloy TitanBor is added. Also this addition of TitanBor improves the grain refining effect (ie by substance entry the number of germs in the casting melt is increased) KS Kolbenschmidt GmbH, 74172 Neckarsulm
- the finished piston is alfiniert, wherein the material for Alfinieren BerylliumVanadium is added.
- the addition of beryllium vanadium in the alfin material improves its adhesion to the surface of the piston and moreover advantageously reduces the slurry history.
- the inventive method for producing the piston using the claimed piston alloy offers a comparison with known casting process piston higher vibration resistance, which is increased by at least 15% over the previously known fatigue strength, measured at room temperature and at 350 0 C. This results in a higher load capacity of the piston during operation of the internal combustion engine, accompanied by a significant reduction in weight. Also, higher material hardness can be achieved, which advantageously eliminates the elimination of the previously performed heat treatment (solution annealing) of the cast piston blank or the finished machined piston.
