Description
Verfahren zum Herstellen zunderbeständiger Lötkolbenarbeitsstücke Die Erfindung bezieht sich auf ein Verfahren zur Herstellung zunderbeständiger Lötkolbenarbeitsstücke, wobei die Oberfläche des kupfernen Lötkolbenarbeitsstückes durch eine thermische Diffusionsbehandlung mit zunderbeständigem Metall angereichert wird.Process for producing scale-resistant soldering iron workpieces The invention relates to a method for producing scale-resistant soldering iron workpieces, wherein the surface of the copper soldering iron workpiece by a thermal Diffusion treatment is enriched with non-scaling metal.
Es ist bekannt, Eisengegenstände auf galvanischem Wege mit einer Zink- und einer Zinnschicht zu versehen, um die Gegenstände vor Korrosion zu schützen.It is known to galvanically treat iron objects with a zinc and to provide a layer of tin to protect the objects from corrosion.
Weiterhin ist es bekannt, in ein aus Kupfer bestehendes Lötkolbenarbeitsstück eine Schicht aus Aluminium oder Aluminiumlegierungen einzudiffundieren. Auch ist ein spezielles Pulvergemisch vorgeschlagen worden, um den Diffusionsvorgang zu verkürzen und eine größere Schichtdicke zu erreichen. Jedoch ist es dabei notwendig, daß die das Lot aufnehmende Spitze nicht mit der Schicht versehen wird, da diese das Lot nicht hält. Es wird daher entweder verhindert, daß sich auf der Spitze eine Aluminiumschicht bildet, oder die Schicht wird nachträglich durch spanabhebende Bearbeitung wieder entfernt. Gerade dadurch aber kann wieder eine Verzunderung der Spitze des Lötkolbenarbeitsstückes eintreten. Zwar wird beim Verzinnen der Spitze Zinn in diese hineindiffundiert, jedoch hat man in der Praxis die Erfahrung gemacht, daß diese Verzinnung nicht lange vorhält, d. h. daß die Lötkolbenspitze, in verhältnismäßig kurzen Zeitabschnitten verzundert, nicht mehr benetzbar ist und durch spanabhebende Bearbeitung und erneutes Verzinnen wieder benetzbar gemacht werden muß.It is also known to use a soldering iron workpiece made of copper diffuse a layer of aluminum or aluminum alloys. Also is a special powder mixture has been proposed to shorten the diffusion process and to achieve a greater layer thickness. However, it is necessary that the the solder-absorbing tip is not provided with the layer, as this is the solder does not hold. It is therefore either prevented that an aluminum layer forms on the tip forms, or the layer is subsequently restored by machining removed. Precisely because of this, however, scaling of the tip of the soldering iron workpiece can again occur enter. While tin is diffused into the tip when tinning, however, it has been found in practice that this tinning does not last long holds, d. H. that the soldering iron tip, in relatively short periods of time scaled, is no longer wettable and by machining and again Tinning must be made wettable again.
Demgegenüber ist nun die vorliegende Erfindung dadurch gekennzeichnet, daß in das Lötkolbenarbeitsstück zuerst eine Schicht aus Zink und danach eine Schicht aus Zinn eindiffundiert ist. Dadurch erhält man eine gut benetzbare Lötkolbenspitze, die, im Gegensatz zu der bekannten Maßnahme, nicht von der sie schützenden Schicht befreit werden muß.In contrast, the present invention is now characterized in that that in the soldering iron workpiece first a layer of zinc and then a layer diffused from tin. This results in a well wettable soldering iron tip, which, in contrast to the known measure, does not depend on the protective layer must be freed.
Ein gemäß der Erfindung hergestelltes Lötkolbenarbeitsstück läßt sich verhältnismäßig billig herstellen und besitzt den Vorteil, daß seine Oberfläche auch bei Dauerbetrieb praktisch nicht verzundert, dabei jedoch eine sehr gute Benetzbarkeit für Lot besitzt.A soldering iron workpiece made in accordance with the invention can be relatively cheap to manufacture and has the advantage that its surface Practically not scaled even with continuous operation, but very good wettability for Lot owns.
Das Eindiffundieren des vorzugsweise folienförmigen Zinkes in die gesamte Oberfläche des Kupferkernes erfolgt vorteilhafter Weise bei einer Temperatur von ungefähr 720° C und in einer Schichtstärke von etwa 0,08 mm. In einem zweiten Verfahrensschritt wird dann in das so. vorbehandelte und mechanisch z. B mit einer Bürste gesäuberte Arbeitsstück Zinn bei einer Temperatur von etwa 780° C, also schon im Verdampfungsbereich dieses Metalls, eindiffundiert, so daß die Außenfläche des Stückes nunmehr aus Zinnoxyd, dem eigentlichen Träger der Zunderbeständigkeit, besteht. Ohne von- dem Grundgedanken der Erfindung abzugehen, ist es auch möglich, die gewiinschten Schichten auf den Kupferkern durch Feuerverzinken bzw. Feuerverzinnen und anschließende entsprechende Wärmebehandlung aufzubringen.The diffusion of the preferably foil-shaped zinc into the The entire surface of the copper core is advantageously carried out at one temperature of about 720 ° C and in a layer thickness of about 0.08 mm. In a second Process step then becomes so. pretreated and mechanically z. B with a Brush cleaned work piece of tin at a temperature of about 780 ° C, so already in the evaporation area of this metal, diffused so that the outer surface of the The piece now consists of tin oxide, the actual carrier of the scale resistance. Without departing from the basic idea of the invention, it is also possible to use the desired Layers on the copper core by hot-dip galvanizing or hot-dip tinning and subsequent to apply appropriate heat treatment.
