Description

Verfahren zur elektrolytischen Herstellung von dünnen Titanüberzügen auf Grundmetallen Im Hauptpatent 582 5a8 ist ein Verfahren zur elektrolytischen Herstellung von dünnen molybdän-, wölfram-, vanadin-, beryllium-, wismut- und tantalhaltigen Überzügen auf Grundmetallen, wie Eisen oder Kupfer, beschrieben, wobei man starkalkalische Laugen mit den Oxyden oder Hydroxyden der betreffenden Metalle sättigt, zweckmäßig unter Verwendung eines Überschusses - der Verbindungen als Bodenkörper, und die so erhaltene Lösung bzw. Aufschlämmung, gegebenenfalls bei erhöhter Temperatur und mit einer Stromdichte von weniger als i o Amp./qdm, unter Verwendung des Grundmetalls als Kathode elektrolysiert. Gemäß einer besonderen Ausführungsform kann die Elektrolyse unter Verwendung eines Diaphragmas zur Abgrenzung des Anodenraumes durchgeführt werden.Process for the electrolytic production of thin titanium coatings on base metals The main patent 582 5a8 describes a process for the electrolytic production of thin coatings containing molybdenum, tungsten, vanadium, beryllium, bismuth and tantalum on base metals such as iron or copper saturates strongly alkaline lyes with the oxides or hydroxides of the metals in question, expediently using an excess - of the compounds as sediment, and the resulting solution or slurry, optionally at an elevated temperature and with a current density of less than 10 amp./qdm, below Use of the base metal as a cathode is electrolyzed. According to a particular embodiment, the electrolysis can be carried out using a diaphragm to delimit the anode space.

In weiterer Ausbildung des Erfindungsgedankens des Hauptpatents wurde gefunden, daß das beschriebene Verfahren mit Vorteil auch für die Herstellung von Titanüberzügen Verwendung finden kann.. Beispiel In einer Lösung von 7 5 g Na O H in 15 o ccm Wasser wurden 16 g. Ti(O H)4 (erbalten durch Fällung von Titanchloridlösung mit Ammoniak und Trocknung bei ioo° C) suspendiert und bei 9o bis 95°Cmit einer kathodischen Strom- 30 dichte von o,6-25 Amp./qdm elektrolysiert. Auf der Kupferkathode wurden nach Verbrauch von o,i Amp./Std. 20,5m9 eines metallischen Niederschlages mit 98,6 % Ti erhalten.In further development of the inventive concept of the main patent was found that the process described is also advantageous for the production of Titanium coatings can be used .. Example In a solution of 7 5 g Na O H in 15 o cc of water became 16 g. Ti (O H) 4 (obtained from the precipitation of titanium chloride solution suspended with ammonia and drying at 100 ° C) and at 9o to 95 ° C with a cathodic current density of 0.6-25 Amp./qdm electrolyzed. On the copper cathode were after consumption of o, i Amp./hr. 20.5m9 of a metallic deposit obtained with 98.6% Ti.
