Thus, the storage zone becomes preferable kept at a temperature that is optimal Spray temperature corresponds to, but also lower than the temperature for melting can be.
- a metallic material provides the Main component and the at least other metallic Material is the minor component.
- the main component can Be magnesium or a magnesium alloy, for. Eg AZ91, AM60 or AS41.
- the first material that made up the main component is, can via a metering device, preferably a Dosing screw, the material supply opening of a Feeding hopper or the like reservoir supplied become.
- the reservoir can this material be supplied for example with a suction conveyor.
- the delivery characteristic of the dosing screw, d. H. of the Mass flow of this material as a function of the Screw speed must be used to determine the metered Quantity to be determined.
- the second material so the minor component can z. B. act to a pure element.
- the second material may also be from a hopper or the like Reservoir via a metering device, preferably a screw feeder or a chamber feeder, the Material supply to be supplied. The delivery characteristic This second metering device must also be determined become.
- an inert gas which fed to the material supply port becomes, the admission of air into the screw extruder becomes prevented.
- This can be done at the material supply opening Approach be provided, with an inert gas is provided to fill the approach with inert gas.
- Inert gas is preferably used argon, as it is a higher density than air and thus the air from the Approach displaced.
- Alloy elements are alloyed, the conventional melt metallurgical process to burn-off problems due to the high melting temperature and / or the high Oxygen affinity, for example calcium, Silicon, hafnium, yttrium and cerium.
- the oxygen affinity of the alloyed metallic material may be larger than that of magnesium.
- the oxygen affinity of a metal generally corresponds to its normal potential in the Voltage range.
- Alloy elements alloyed with a normal potential in particular which is more negative than -2 volts
- Alloy elements with a normal potential the more negative than that of magnesium (-2.37V), for example Calcium, hafnium, yttrium or cerium.
- Alloy elements with a high melting point of more be alloyed as 1000 ° C, for example silicon.
- alloying elements can be alloyed which, due to their high vapor pressure, tend to to evaporate, z.
- sodium, potassium, zinc For example, zinc has B. a vapor pressure of about 100 mbar at 620 ° C and about 1000 mbar at 900 ° C.
- alloying elements use that only limited or not at all in the Base metal are soluble, so they float or too Soil sink. So can magnesium as a base metal z.
- alloying elements too soluble, with a high atomic weight, especially those with a much higher atomic weight than that Base metal can be used without a Gravity segregation occurs.
