Description

Verfahren zum Verzinken und Verzinnen von metallen oder 1Vletallegierungen. Gegenstand der Erfindung ist ein Verfahren zum Verzinken oder Verzinnen von Metallen oder Metallegierungen.Process for galvanizing and tinning of metal or 1Vletal alloys. The invention relates to a method for galvanizing or tinning metals or metal alloys.

Wenn man zur Herstellung von Zink oder Zinnüberzügen auf Metallen oder Metallegierungen Bäder aus den geschmolzenen Überzugsinetallen anwendet und in diese die zu überziehenden Gegenstände eintaucht, so ergibt sich häufig der Übelstand, daß das zu überziehende Metall angegriffen wird und teilweise in Lösung geht. Dies ist besonders dann unerwünscht, wenn es darauf ankommt, die Oberflächengestaltung des zu überziehenden Gegenstandes genau zu erhalten, ferner auch, wenn es darauf ankommt, ein fest bestimmtes Verhältnis zwischen zu überziehendem Metall und Überzugsmetall aufrechtzuerhalten. Letzteres ist beispielsweise dann der Fall, wenn die verzinkten oder verzinnten Gegenstände durch eine Erhitzung auf geeignet ausgewählte Temperaturen derart verändert werden sollen, daß der Zink- oder Zinnüberzug als solcher vollständig * verschwindet und sich an der Oberfläche eine Legierungsschicht bildet, deren Gehalt an dem Überzugsmetall nach außen hin allmählich und regelmäßig abnimmt.When going to manufacture zinc or tin coatings on metals or metal alloys using baths from the molten coating metals and in which the objects to be covered are immersed, the inconvenience often arises, that the metal to be coated is attacked and partially goes into solution. this is particularly undesirable when it comes to surface design of the object to be coated exactly, also if it is on it arrives, a fixed ratio between the metal to be plated and the plating metal maintain. The latter is the case, for example, when the galvanized or tinned objects by heating to suitably selected temperatures should be changed in such a way that the zinc or tin coating as such is complete * disappears and an alloy layer forms on the surface, the content of which on the coating metal gradually and regularly decreases towards the outside.

Diese Gefahr der Lösung des zu überziehenden Metalls in dem geschmolzenen Bade wird gemäß der Erfindung dadurch beseitigt, daß man das Bad mit dem zu überziehenden Metall vorher sättigt. Besteht das zu überziehende Metall aus einer Legierung, so ist es vorteilhaft, das Überzugsbad mit einigen oder sämtlichen Bestandteilen der Legierung zu sättigen. Eine Auflösung von Teilen des zu überziehenden Metalls in dem Überzugsbad wird auf diese Weise vollständig vermieden.This risk of the metal to be coated dissolving in the molten one Bath is eliminated according to the invention by the fact that the bath with the to be coated Metal saturates beforehand. If the metal to be coated consists of an alloy, so it is advantageous to use the coating bath with some or all of the components of the Saturate alloy. A dissolution of parts of the metal to be coated in the coating bath is completely avoided in this way.
