Definitions
- Component in particular piston, consisting of two different materials
- the invention relates to a method for producing a component consisting of two different materials according to the preamble of claim 1.
- EP-OS 0 353 480 discloses a method for introducing a local reinforcement, consisting of an iron-based material, into an aluminum piston.
- the component to be introduced is first coated on the surfaces to be contacted with aluminum with a material which consists of particles and is also oxidation-resistant even at higher temperatures.
- the method used for this is usually a spraying method, with flame spraying, plasma spraying or arc spraying being possible.
- the part is then preheated, placed in a mold and cast with an aluminum alloy.
- Spray layers are not built up from a homogeneous material, but from many individual, initially molten and then quickly solidified particles. Pores and binding defects both at the interface and in the layer itself can never be completely ruled out. The coating of edges and corners causes considerable problems. Defined layer thicknesses with gradations in the range of a few microns cannot be produced, and under certain circumstances more material is applied than is absolutely necessary.
- a further disadvantage lies in the limitation of the layer materials, which according to the invention must also be resistant to oxidation even at higher temperatures, since otherwise oxide layers form during preheating, which lead to poor adhesion between the layer and the casting material.
- the invention is therefore based on the problem of providing a part to be cast with a layer which is homogeneous, has no binding defects or internal defects, has good layer adhesion both against iron or copper-based alloys and against aluminum-based alloys and thus leads to a consistently high load capacity of the composite material.
- the strength of the composite material according to the invention is said to far exceed the strength of the Alfin ring carrier bond which has been known for around 40 years and has been produced in series for the majority of pistons for diesel engines since the firing pressures of these pistons and thus the Burdens in the last years have risen significantly.
- the characteristic feature of claim 1 shows a solution to this problem.
- the galvanic application of a chrome layer to the iron or copper-containing part in connection with the further process steps of the Alfin process creates a homogeneous and well-adhering connection with the aluminum-based alloy.
- the selection of the alloys for the immersion bath according to feature b) of the preamble is not limited to the Al alloys normally used in the Al-Fin process, but other immersion baths, preferably based on zinc or tin, can also be used be used.
- the strength of the bond increases significantly compared to the alfine bond.
- a Ni resist component composition approx. 2.6% C / 2, 1% Si / 1, 2% Mn / 15% Ni / 1, 3% Cr / 6% Cu, rest Fe
- a Ni resist component composition approx. 2.6% C / 2, 1% Si / 1, 2% Mn / 15% Ni / 1, 3% Cr / 6% Cu, rest Fe
- the binding strength of samples produced in this way is 140-150 N / mm.
- the binding strength of correspondingly produced samples without a chrome layer is only 50-60 N / mm. If both processes are carried out on a component made of CuNi2Si, the first process involves the
- FIG. 1 shows the layer structure according to the invention in cross section:
- NiResist material 1 Between a previously defined NiResist material 1 and an AlSi material 4 there is a bonding layer made of electrodeposited chromium 2, which has a seam 3 made of intermetallic phases on the AlSi side.
