Definitions
- the invention relates to a component of an internal combustion engine according to the kind defined in the preamble of claim 1.
- the invention further relates to a method for producing a component of an internal combustion engine.
- the thermally highly stressed area is changed in such a way that this thermally highly stressed area has a higher elongation at break than the rest of the component.
- the component can tolerate greater strains without damage in the region which is subject to high thermal stress. Due to the increased elongation at break and the improved toughness at room temperature and at higher temperatures, the eventual occurrence of material fatigue or crack formation can occur at a later point in time or at higher loads. be moved. This makes it possible to implement internal combustion engines with higher outputs and / or a longer service life.
- the strength of the component is changed only to such an extent by the solution according to the invention that purely mechanical loads cannot have a negative influence on the component, since the entirety of the component can be designed with the strength required for the mechanical loads to be expected and only thermally highly stressed area an increased elongation at break is required. This is very important, for example, when introducing screw forces.
- an increase in strength always leads to a reduction in the elongation at break, which inevitably results in material cracks or the like when higher stresses occur.
- the solution according to the invention represents an optimal compromise of sufficient strength and high elongation at break.
- the thermally highly stressed area has a greater aluminum content than the entire component.
- a component in which the solution according to the invention can be used in a particularly advantageous manner is a cylinder head.
- the thermally highly stressed area is preferably the land area located between the respective valve bores.
- the alloy composition in this highly stressed area can be controlled particularly precisely. In the case of the In contrast to the methods known from the prior art, these methods are more of an “alloying” than an “alloying”.
- Figure 1 is a view of the interface of a cylinder head of an internal combustion engine.
- FIG. 2 shows a section through a web area of the cylinder head according to line II-II from FIG. 1 in a first state
- FIG. 3 shows the land area of the cylinder head from FIG. 2 in a second state
- FIG. 5 shows the land area of the cylinder head from FIG. 2 in a fourth state.
- Fig. 1 shows a component 1 of an internal combustion engine, not shown in its entirety.
- component 1 is a cylinder head 1 a, which consists of an aluminum material, preferably an aluminum-silicon alloy.
- the component 1 has a plurality of regions 2 which are subjected to high thermal loads. In the present case, these are web areas 2a located between respective valve bores 3. Since the internal combustion engine belonging to the cylinder head la has three or six cylinders, a total of three land areas 2a are provided. see.
- the web areas 2a are essentially cruciform, since four valve bores 3 are provided for each cylinder. If only two valve bores 3 were provided per cylinder, the web areas 2a could also be linear. In any case, the thermally highly stressed area 2 is relatively small in comparison with the entire component 1.
- the component 2 shows the component 1 with the thermally highly stressed area 2 or the web area 2a in its untreated state.
- the component 1 is preferably produced by casting.
- the region 2, which is subjected to high thermal loads is heated by means of a blasting method, for which purpose a laser beam 4 is used.
- a melt pool 5 is created in the region 2, which is subject to high thermal stress.
- an electron beam or the like could also be used.
- a fine-grained structure would result in the thermally highly stressed area 2 after rapid cooling, which leads to better material properties, in particular with regard to an increase in toughness or elongation at break.
- an additional material 6 is introduced into the molten bath 5.
- This additional material 6, which preferably has a larger aluminum content than the entire component 2 can be in the form of a powder or which can also be introduced into the molten bath 5 in the form of a solid material.
- the additional material 6 has a silicon content of 1 to 5% by weight, a magnesium content of less than 0.25% by weight and an iron content of less than 0.1% by weight. % on.
- the additional material can also consist of pure or approximately pure aluminum.
- a component 1 is formed which in its entirety consists of an aluminum alloy which meets the mechanical requirements with regard to strength, for example screw holes which are not shown , can be adjusted.
- the component 1 has a changed alloy composition, which leads to the region 2 which is subject to high thermal stress having a greater elongation at break than the entire component 1.
- there is also an improved toughness within the region 2 which is subject to high thermal stress the very good thermo-mechanical properties of which are thereby improved.
- the component 1 can of course be machined in a known manner.
- the depth of the area 2 with the changed alloy composition is preferably 0.2 mm to 5 mm.
- the composition of the additional material 6 could be changed in stages so that there is a gradual increase in the elongation at break in the direction of the surface of the component 1.
- the size of the molten bath 5 produced results in each case from the amount of the brought energy.
- a transition from region 1 to region 2 which is gradient-shaped with respect to the coefficient of expansion can also be expedient. The coefficient of expansion changes continuously.
