Description

Verfahren zur Verbleiung von Netallen Es ist schon lange bekannt, daß man Eisen verbleien kann, indem man das an der Oberfläche gereinigte Eisen mit einer Lösung von Chlorzink bestreicht und nun heißes Blei aufwalzt. Hierdurch erzielt man zwar eine Verbleiung, die jedoch an. dem Übelstand leidet, daß zwischen Blei und Eisen Reste von Chlorzink zurückbleiben, welche korrodierend wirken. Außerdem läßt sich nach diesem Verfahren eine absolut homogene Verbindung zwischen dem Grundmetall und dem Blei nicht erzielen.Process for the leading of nets It has been known for a long time that iron can remain by adding the iron that has been cleaned on the surface coated with a solution of zinc chloride and then rolled on hot lead. This is achieved there is a lead, but it does. the evil that suffers between lead and iron residues of zinc chloride remain, which have a corrosive effect. aside from that This process allows an absolutely homogeneous connection between the base metal and the lead did not achieve.

Es ist ferner bekannt, daß man eine gute homogene Verbleiung erreicht, wenn das Grundmetall zunächst verzinnt wird und dann auf diese verzinnte Schicht flüssiges Blei aufgetragen wird. Dieses Verfahren ist teuer, da zunächst der ganze Gegenstand verzinnt werden muß, außerdem tritt beim Auftragen des geschmolzenen Bleies eine Legierung des geschmolzenen Bleies mit dem Zinn ein, wodurch die Widerstandsfähigkeit der Bleischicht gegen chemische Reaktionen herabgernindert wird.It is also known that a good homogeneous lead can be achieved, when the base metal is tinned first and then onto this tinned layer liquid lead is applied. This procedure is expensive because the whole thing is initially Item must be tinned, moreover occurs when applying the molten Lead an alloy of the molten lead with the tin, increasing the resistance the lead layer is reduced against chemical reactions.

Die Nachteile des ersten und zweiten Verfahrens lassen sich dadurch beheben, daß das Grundmetall mit einer Auflösung von Halogeniden des Zinks, der geringe Mengen von Halogenidendes Zinns beigefügt sind, bestrichen wird. Sobald der so behandelte Gegenstand erwärmt wird, fließt darauf gebrachtes flüssiges Blei glatt aus, und man erreicht in einer Operation eine absolut sichere homogene Verbleiung, die mechanischen und chemischen Beanspruchungen gegenüber sich als außerordentlich widerstandsfähig erwiesen hat. Das Verfahren läßt sich anwenden auf Metalle, wie Eisen, Messing, Kupfer, Bronze bzw. ähnliche Metalle oder Metallegierungen.The disadvantages of the first and second methods can be eliminated fix that the base metal with a dissolution of halides of zinc, the small amounts of tin halides are added. As soon the object treated in this way is heated, liquid lead applied thereto flows smooth, and you can achieve an absolutely reliable homogeneous lead in one operation, the mechanical and chemical stresses on each other as extraordinary has proven to be resilient. The method can be applied to metals such as Iron, brass, copper, bronze or similar metals or metal alloys.
