Definitions
- Aluminum containing small amounts of manganese constitute a class of known alloys.
- 3003 alloy contains 1%% manganese (nominal) and has the high corrosion resistance of pure aluminum but a much higher strength.
- Aluminum alloys may contain much less manganese, down to about 0.1% manganese, such as the 5056 alloy.
- the addition of manganese metal to molten aluminum to provide final alloys of this type is generally prohibitive because of the extremely slow rate of dissolution thereof in the molten aluminum.
- the method of the present invention for adding manganese metal to molten aluminum to provide a manganesecontaining aluminum alloy involves the improvement wherein the manganese metal added to the molten aluminum has thereon a coating containing a potassium fluoride and which forms a molten phase at the temperature of the molten aluminum.
- the coating contains at least one other chemically bound metal selected from the group consisting of sodium, aluminum, manganese, titanium and zirconium.
- the stated coating may be formed on the manganese by: (a) applying to the manganese a dispersion (solution or suspension) prepared by dispersing in water the required potassium-fluoride compound or compounds, followed by drying; or (b) applying to the manganese a melt prepared by melting the required potassium-fluoride compound or compounds, followed by solidification.
- the manganese metal additive of the present invention hence, comprises a manganese body having thereon the stated coating and is prepared by providing on a manganese body the stated coating as by applying the required material in molten form or as a dispersion to the manganese body followed by solidification of the molten coating or drying of the dispersion.
- the manganese metal additive of the present invention when added to molten aluminum, dissolves at a much more rapid rate than a similar body of manganese without the coating.
- the exact reason for this is not presently known; however, it may be theorized that the coating enhances wetting of the manganese surface by the molten aluminum, possibly either by virtue of the formation of the molten phase when added to the molten aluminum or by virtue of having attacked the manganese oxide film on the original manganese metal body, or both.
- the manganese body may be in the form of free powder, in the form of shaped bodies (e.g. briquets) formed from powder, in massive form as obtained by casting from molten manganese with or without subsequent crushing, in the form of chips (the form recovered by breaking electrolytic manganese away from the cathode onto which it was initially plated) or in the form of electrolytic manganese plated onto an aluminum cathode (that is, the manganese body may be an aluminum body, such as a sheet, having an electrolytic manganese deposit thereon).
- shaped bodies e.g. briquets
- chips the form recovered by breaking electrolytic manganese away from the cathode onto which it was initially plated
- the manganese body may be an aluminum body, such as a sheet, having an electrolytic manganese deposit thereon.
- electrolytic manganese chips are highly satisfactory and economical, they represent the preferred form of manganese utilized in accordance with the present invention.
- electrolytic manganese it is preferred initially to remove adhering electrolyte as by washing or by a combination of suitable chemical treatment and washing.
- the manganese body is provided with a coating containing a potassium fluoride and which forms a molten phase at the temperature of the molten aluminum to which the coated manganese body is added.
- the coating will form a molten phase at or below about 710 C. Since pure potassium fluoride (KF) melts well above this temperature, the coating will have present therein at least one other chemically bound element which serves to lower the melting point of the coating.
- KF potassium fluoride
- the coating will have present therein at least one other chemically bound element which serves to lower the melting point of the coating.
- such element is a metal selected from the group consisting of sodium, aluminum, manganese, titanium and zirconium.
- the chemically bound metal may be combined with the potassium fluoride as a complex fluoride, such as a coating derived from potassium titanium fluoride, potassium zirconium fluoride, potassium aluminum fluoride, potassium manganese fluoride, or the like.
- Coatings derived from such complex fluorides may be provided by dispersing in water, or melting, the stated compounds themselves or by employing a mixture of compounds which result directly in such a complex.
- coatings, derived from such complex fluorides may be provided by employing a mixture of compounds which, at least partially through reaction with the manganese itself, result in such a complex potassium manganese fluoride in the coatmg.
- the chemically bound metal may not be combined chemically with the potassium fluoride as a complex fluoride, but may be present as a compound in admixture with potassium fluoride so long as the coating forms the stated molten phase at the temperature of the molten aluminum.
- a coating, formed on the manganese body by applying an aqueous solution of potassium fluoride (KF) and hydrofluoric acid forms, in
- a manganese 7 compound most likely manganese fluoride, as evidenced by reaction between the solution and the manganese surface.
- a coating formed on the manganese body by applying an aqueous solution of potassium fluoride (K1?) and sodium fluoride (NaF) most likely consists essentialy of a mixture of these two fluorides.
- the coating may be applied from aqueous dispersion (solution or suspension) or from a melt.
- a dispersion When applied from a dispersion, the required material is added to water at a concentration which may vary widely and up to and beyond saturation, depending on the solubility of the particular material in water. To the extent the material is present beyond its solubility in water it is in the form of a suspension.
- the term dispersion as used herein is intended to apply to such suspensions as well as to solutions in which substantially no insoluble material is present.
- the dispersion is then applied to the manganese body, as by dipping the body therein, by mixing a plurality of manganese bodies (especially if finely-divided) with the dispersion, or spraying the dispersion onto the body, followed by drying.
- the presently preferred coatings are those formed y applying, to the manganese body, an aqueous dispersion prepared by mixing with water: (a) potassium titanium fluoride; (b) potassium zirconium fluoride; (c) potassium manganese fluoride; (d) a combination of potassium fluoride and hydrofluoric acid; and (e) a combination of potassium fluoride, hydrofluoric acid and manganese fluoride. It is believed that these dispersions attack the manganese oxide film on the manganese body. As among the three mentioned complex fluorides, potassium titanium fluoride is especially preferred.
- the coated manganese body or more likely a number thereof depending on the size of the aluminum heat, is then added to molten aluminum.
- the amount added depends, ofcourse, upon the particular alloy to be formed, and may range as low as about 0.1%, by weight, of manganese. While the present invention is particularly advantageous in preparing final alloys containing up to about 2% manganese, it is also applicable for utilization inthe preparation of master alloys containing up to about 30% of manganese.
- the coating in large part forms slag, although, in the case of coatings derived from the complex potassium titanium-and zirconium fluorides, some of the titanium and/or zirconium may dissolve in the aluminum. Since these materials are beneficial, as being 'well known grain refiners, their presence may provide an additional incidental benefit from the present invention.
- Electrolytic manganese chips ranging in size from about A1" for the smallest dimension up to about A for the largest dimension (the electrolytic manganese had previously been dipped, at room temperature, in an approximately 1% aqueous solution of potassium dichromate, washed with water and dried) were placed in a wire screen basket and dipped, at 90 C., in an aqueous solution prepared by dissolving potassium zirconium fluoride (K ZrF in water to saturation at that temperature. The chips were then dried in warm air. The values set forth in Table I are average from two different samples.
- Electrolytic manganese chips prepared as in l-A but dipped, at 8090 C., in an aqueous solution prepared by dissolving potassium titanium fluoride (K TiF in water to saturation at their temperature, instead of in the solution prepared from potassium zirconium fluoride.
- Electrolytic manganese chips prepared as in l- A but dipped, at room temperature, in an aqueous solution prepared by dissolving 41 g. of sodium fluoride and 84.5 g. of potassium fluoride (KF) in a liter of water, instead of in the solution prepared from potassium zirconium fluoride.
- Electrolytic manganese following removal from the electrolytic cell was simply washed with water, removed from the cathode, heated to 15001800 F. to remove hydrogen and graded into chips having the dimensions of the chips in Example 1. The chips were then dipped, at 8090 C., in an aqueous solution prepared by dissolving potassium zirconium fluoride in water to saturation at that temperature. The chips were then dried in warm air.
- Electrolytic manganese was deposited on both sides of an aluminum sheet about 0.020" thick, until a layer of manganese about thick was formed on each side.
- the resulting sandwich was removed from the cell, dipped in an approximately 1% aqueous solution of potassium dichromate, washed with water and dried. Pieces approximately /8" x /2" were cut from the sandwich, and the pieces were dipped, at 80-90 C., in an aqueous solution prepared by dissolving potassium zirconium fluoride in water to saturation at that temperature. The pieces were then dried in warm air.
- Electrolytic manganese was deposited on both sides of an aluminum sheet as in Example 3 and the resulting sandwich, upon removal from the cell, was held for 10 minutes and then washed with water, without treatment with the dichromate solution, and dried. Pieces were then cut from the sandwich as in Example 3 and the pieces were dipped, at 80-90 C., in an aqueous solution prepared by dissolving potassium zirconium fluoride in water to saturation at that temperature. The pieces were then dried in warm air.
- Electrolytic manganese chips were prepared as in Example 1 but with only Washing of the electrolytic manganese with Water and drying and without treatment with potassium dichromate. The chips were dipped, at 8()90 C., in a solution prepared by dissolving potassium zirconium fluoride in Water to saturation at that tempera ture. The chips were then dried in warm air.
- sodium dichromate may be substituted therefor.
- Example 1-C repeated use of the solution by dipping manganese chips therein, with progressive (but not complete) depletion of hydrofluoric acid by reaction with the manganese producing increased manganese values in the solution, showed similar results in providing faster dissolution of the so-treated manganese chips in molten aluminum.
- said coating contains at least one other chemically bound element serving, with the potassium and fluoride components, to provide said molten phase.
- said element is a metal selected from the group consisting of sodium, aluminum, manganese, titanium and zirconium.
- said coating is formed by applying to said manganese an aqueous dispersion prepared by mixing with water at least one complex potassium fluoride selected from the group consisting of potassium manganese fluoride, potassium titanium fluoride and potassium zirconium fluoride.
