Definitions
- the invention relates to a method for Production of a band-shaped composite material with a base material Made of copper or a copper alloy and with a surface coating of pure tin or a tin alloy.
- tin-plating Bands made of copper materials and. a.
- Connectors, cable lugs, contact parts, solder thread and Battery clips used.
- the processors set high quality standards both the basic material and the Covers. The quality of tinned strips depends crucially from the initial state of the basic material, from the careful Surface preparation before tinning and from the proper one Execution of the tinning process.
- This process also creates a slag as Product of the chemical reaction between the flux and the oxides that negatively affect the production process can. Delayed foot remnants, e.g. B. chlorides in certain cases on the tinned surface Form stains.
- the invention has for its object a method of the type mentioned, in particular liability the tin layer on the base material made of copper or a copper alloy is improved while at the same time Formation of a tin layer of uniform thickness.
- the method according to the invention surprisingly adequate deoxidation and activation achieved the strip surface, so that a full-surface tin layer defined thickness can be applied.
- This Layer is also dense, i. H. there are no continuous Pores on. Forms between the strip surface and the tin layer an intermetallic phase (IMP), which is good Adhesion resistance of the tin layer on the strip surface worries.
- IMP intermetallic phase
- US-A-5,077,094 does disclose a method of manufacture a band-shaped composite material with a Base material made of metal or a metal alloy, esp. Steel, and with a surface coating a tin alloy, in which the base material in a reducing gas atmosphere warms the base material tinned with a layer in the mm range and the composite material is cooled quickly.
- this is a one-sided coating a metal strip, esp. a steel strip, the also i.a. at a temperature of at least 400 ° C, especially for steel at at least 800 ° C must become.
- the invention is explained in more detail using the following exemplary embodiment.
- the figure shows schematically the process sequence according to the invention in the tinning of a strip-shaped base material 1 made of copper or a copper alloy.
- the basic material 1 running from a decoiler 2 is heated to a temperature T of about 200 ° C. after passing through a deflection roller 3 in a prechamber 4 while maintaining a hydrogen-nitrogen atmosphere and immediately thereafter through a tin bath 5 (temperature: 240 ° C.) guided with pulley 6. Excess tin is retained by the stripping 7.
- the composite material 10 arrives at a reel 11.

Description
Die Figur zeigt schematisch den erfindungsgemäßen Verfahrensablauf bei der Verzinnung eines bandförmigen Grundmaterials 1 aus Kupfer oder einer Kupferlegierung. Das von einem Abhaspel 2 ablaufende Grundmaterial 1 wird nach Passieren einer Umlenkrolle 3 in einer Vorkammer 4 unter Einhaltung einer Wasserstoff-Stickstoff-Atmosphäre auf eine Temperatur T von etwa 200 °C erwärmt und unmittelbar anschließend durch ein Zinnbad 5 (Temperatur: 240 °C) mit Umlenkrolle 6 geführt. Überflüssiges Zinn wird von der Abstreifung 7 zurückgehalten. Nach Passieren einer Kühlstrecke 8 und einer Umlenkrolle 9 gelangt das Verbundmaterial 10 (verzinntes Band) auf einen Aufhaspel 11.
