Description

Verfahren zur Erzeugung einer mechanisch und elektrisch hochwertigen Phosphatschicht auf Kupfer und Kupferlegierungen Die Patentschrift 718 7t9 behandelt ein Verfahren zur Erzeugung einer mechanisch und elektrisch hochwertigen Phosphatschicht auf Kupfer und Kupferlegierungen.Method for producing a mechanically and electrically high quality phosphate layer on copper and copper alloys The patent 718 7t9 deals with a method for producing a mechanically and electrically high quality phosphate layer on copper and copper alloys.

Das Verfahren besteht darin, daß die Kupfer-oder Kupferlegierungskärper in einer 3- bis io%igen Eisen-3-Chlorid-Lösung vorbehandelt und danach in einer an sich bekannten Weise phosphatiert werden. Nach der Patentschrift 727 649 wird dieses Verfahren .durch Zusetzen von Alkohol zur wäßrigen Lösung verbessert, wobei ebenfalls 3 bis io% für das Alkohol-Wasser-Gemisch zugrunde gelegt sind.The method consists in that the copper or copper alloy bodies are pretreated in a 3 to 10% iron-3-chloride solution and then phosphated in a manner known per se. According to patent specification 727 649, this process is improved by adding alcohol to the aqueous solution, the alcohol-water mixture likewise being based on 3 to 10%.

Weitere Untersuchungen haben ergeben, daß die Eisen-3-Chlorid-Lösung unter, 3% mit 96%igern Alkohol versetzt, verdünnt werden kann und damit das Aufbringen der Eisenschicht beschleunigt wird. Man kann sogar bis auf eine I/z0/aige alkoholische Eisen-3-Chlorid-Lösung heruntergehen.Further research has shown that the iron-3-chloride solution under, 3% with 96% alcohol added, can be diluted and thus the application the iron layer is accelerated. You can even get up to one alcoholic Iron-3-chloride solution go down.
