- the filling chamber has an insert, preferably made of steel, which is provided with an opening on its lateral surface that is connected to the feed opening of the filling chamber.
- the inner surface of the filling chamber or the inner surface of the said insert completely or partially, then preferably in the filling area, provided or coated with tungsten or a tungsten alloy.
- the insert has about% of the length and about half the wall thickness of the filling chamber.
- the insert according to the invention in contrast to the insert described in EP 3 184 203 A1, is not an interchangeable socket in the form of a sleeve system in which a molybdenum insert is inserted precisely into an outer sleeve made of steel, but the inner surface of the invention Insert, which is usually made of steel, is wholly or partly with tungsten or a
- the filling chamber according to the invention can correspond to that from EP 3 184 203 A1.
- Tungsten or a tungsten alloy is used as the coating material for the inner surface of the filling chamber or the insert according to the invention, the inner surface of the filling chamber and insert preferably being completely coated.
- the alloy can be a binary, ternary or quaternary or an alloy with further (metallic) components. Examples of this are WNiFe alloys with preferably more than 50% by weight of tungsten (W) or WMoNiFe alloys in which the sum of W and Mo is more than 50% by weight of the finished alloy.
- Particularly suitable alloys contain more than 50% by weight of tungsten.
- Particularly suitable forms for tungsten and tungsten alloys are wire and powder forms. The production takes place according to the person skilled in the art
- Tungsten alloys from various manufacturers and metal trading companies, etc. a. offered on the Internet.
- Coating materials also apply to the coating of metal substrates in general.
- the surface coating process of thermal spraying has proven to be particularly suitable for the purposes of the invention.
- this method leads to a very strong hardening of the sprayed layer of typically> 800 HV Vickers hardness, while e.g. Otherwise tungsten alloys only have a hardness between 280 and 400 HV.
- the surface coatings applied by thermal spraying are also characterized by e.g. due to their special resistance to liquid aluminum and are therefore preferred and particularly suitable for use in aluminum die-casting systems.
- Thermal spray processes include the following processes:
- the invention thus also relates to the coating method with which the materials are applied.
- the methods of thermal spraying are
- the surface condition also has an influence on quality features such as adhesive strength.
- Electric arcs arc spraying
- plasma jets plasma spraying
- Fuel-oxygen flame or fuel-oxygen high-speed flame (conventional and high-speed flame spraying), fast, preheated gases (cold gas spraying) and laser beam (laser beam spraying).
- the spraying processes are classified according to these criteria.
- the preferred method is wire arc spraying.
- Plasma spraying is particularly suitable for powdery W / W alloys.
- the applied coatings lead.
- thermal spraying processes and also the process for welding the coating materials on are preferred according to the invention.
- the thermal spray processes offer a wide range of applications for
- arc spraying is particularly preferred according to the invention, which is used both in the so-called two-wire process and particularly preferably in the so-called single-wire process.
- the preferred coating material is tungsten or tungsten alloys. The preferred coating or spraying process is described in greater detail below by way of example with reference to FIG. 1, without the subject matter of the present invention

- the arc is between two wires and in
- the plasma 4 consists of a gas mixture of protective gas 1, that is argon or argon / hydrogen (Ar / ArFh) with atomizer gas 3.
- the electrode 1 remains exclusively surrounded by protective gas 2 and thus protected.
- the arc 4 melts the spray wire 7 before the atomizing gas 5 atomizes the melted droplets of the spray wire 7 at very high pressure or at very high speed.
- the atomized spray wire with atomizer and protective gas is with
- Reference numeral 8 denotes.
- the atomizer gas flow does not have to be as with the
- Plasma welding run in a ring around the shielding gas 2, it can e.g. can also be flowed in through nozzles. In this case, the one shown in FIG.
- Atomizer gas nozzle 6 is omitted and replaced by individual nozzles.
- the spatial separation between electrode 1 and wire 7, with the electrode 1 being able to rotate around wire 7, enables cheaper nitrogen gas to be used instead of noble gases.
- the hardness can be increased to approx. 600 HV compared to the starting material with approx. 300 HV. It has been shown that with air as the atomizer gas 5, a further substantial increase in hardness to approx. 900 HV can be achieved.
- currents in the range of 60-159 A are preferably used.
- the present invention results in particular in longer service lives of the heavily used filling chamber and thus also in longer service lives of a
- corresponding die casting system and comprises a coated filling chamber or a corresponding insert, a method for coating these components, the correspondingly equipped die casting system and the use of tungsten or tungsten alloys for coating (wholly or partially) the filling chamber or filling chamber insert.
- Metal substrates coated according to the invention in general.
- W / W alloys are less brittle and they are also less sensitive to oxidation.
- Thermal spraying preferred according to the invention allows not only an insert to be protected, but the entire filling chamber.
- the injection molding hardens the materials, which means not just one
- welding or welding of a W / W alloy onto the substrate to be protected also improves the thermal, chemical and mechanical properties of its (coated) surface.
- the hardness of the welded-on W / W alloy is also significantly improved compared to the normal value, but usually does not reach the values that can be achieved by thermal spraying.
- the welding is carried out with the usual welding processes such as TIG, MIG, MAG welding.
