Definitions
- the present invention relates to an insert made of a aluminum material for remelting or joining by cast iron with a melt of aluminum or a aluminum alloy to form a casting composite with metallic bond in the surface composite limit.
- the East German patent DD-141 121 discloses a process according to the preamble of claim 1, wherein the insert is provided of a metallic coating after fluxing by immersion in a bath metallic (molten lead) which has a high ability to combine with alminium. But fluxing treatment can, for shaped inserts complicated, leave remnants of flux and alter at points corresponding bond adhesion.
- the inventor set himself as objective of preparing an insert of the type mentioned in start, with which the melting temperature can be kept as low as possible during casting composite and bond adhesion can be further improved.
- the invention also provides a composite casting such as defined in claim 10.
- the invention it becomes possible to use as a material for inserts the whole range of aluminum materials and at the same time achieve high bond adhesion in the composite casting.
- the first layer we ensure the second layer good adhesion with metallic bond.
- the first layer is in the simplest case carried out uniformly in a single metal or metal alloy. he However, it is already sufficient that only the surface layer of the first layer consists of a metal or alloy resistant to oxidation.
- the first layer can therefore also be a multi-layered system whose layer external is formed of a metal or metal alloy resistant to oxidation.
- Metals suitable for the first layer or surface layer of it are Z, Cd, Cr, Cu, as well as Ag, Au, Ni in particular and alloys of these elements.
- a layer thickness of 0.002 to 20 ⁇ m is generally sufficient, while in most cases the thickness may be less at 5 ⁇ m and in principle even a layer thickness of a few rows of atoms may suffice.
- the second layer melting relatively low, of the surface of the insert, care must be taken that when from composite casting to the boundary surface between the insert and the molten metal mass, there is during a sufficient duration a liquid layer which ensures the interdiffusion membership.
- Metals or alloys suitable metals with high solubility in aluminum in the solid state i.e. what we call brazing filler alloys, are zinc or zinc alloys such as ZnAl5, ZnMg3 and ZnCu5, while that the exact content of alloying element may vary in a relatively wide range and that we can thus adjust the desired melting temperature.
- ZnAl5, ZnMg3 and ZnCu5 zinc or zinc alloys
- Thickness of the second layer is preferably between 20 and 300 ⁇ m.
- the second layer can be provided directly with a third layer corresponding to the first layer in terms of choice of material and thickness. It is also possible to use as a third layer, instead of a metal which is stable against oxidation, a layer of flux or flux, the latter being able to be applied for example by dipping in a flux or even being able to be done. by depositing a flux on the mass of molten metal directly during the composite casting, on the surface of the insert.
- An appropriate flux is for example K 2 ZrF 6 .
- the aluminum material of the insert according to the invention can for example include an alloy with difficulty flowable, intermetallic phases, materials spray compacted or sintered, as well as very generally composite materials with aluminum matrix, possibly reinforced with ceramic particles, short fibers, whiskeys or barbs or continuous fibers, as well as shapes hybrids and other special alunimium materials.
- the first layer, or at least the layer surface can be deposited on the insert surface by immersing the insert in a molten bath of metal or alloy resistant to the oxidation that we chose and applying simultaneously with the insert of ultrasonic vibrations. These vibrations have the effect of releasing by action mechanical the oxide layer present on the surface of the insert and therefore to obtain good adhesion of the surface layer resistant to oxidation.
- the second layer is preferably applied in the dip coating process.
- a composite casting we place usually the insert in a mold - which can also be a shell for die casting - and we redesign or we join by the cast iron with the mass of molten metal.
- a composite casting can also have several inserts.
