Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum chemischen Metallisieren von Keramikkörpern, bei dem der Keramikkörper zu nächst geätzt, danach mit einer Palladium-Lösung aktiviert und anschließend chemisch metallisiert wird.The invention relates to a method for chemical Metallizing ceramic bodies, in which the ceramic body too next etched, then activated with a palladium solution and is then chemically metallized.
Es ist ein Verfahren zum chemischen Metallisieren von Aluminiumoxidkeramiken bekannt (Zeitschrift "Plating and Surface Finishing", September 1987, Seiten 62 bis 67), bei dem mehrere chemische Substanzen zum Ätzen verwendet werden können, von denen einzelne den Vorzug haben, daß sie zu einer verhältnis mäßig haftfesten Metallschicht auf dem behandelten Aluminiumoxid- Keramikkörper führen. Versucht man die beim Ätzen von Aluminium oxid-Keramikkörpern bewährten Substanzen auch zum Ätzen von piezokeramischen Körpern einzusetzen, dann stellt man in Versuchen fest, daß in derartiger Weise vor dem eigentlichen chemischen Metallisieren vorbehandelte Piezokeramikkörper hinsichtlich der Haftfestigkeit der Metallschicht den gestell ten Anforderungen nicht gerecht werden.It is a process for the chemical metallization of Alumina ceramics known (magazine "Plating and Surface Finishing ", September 1987, pages 62 to 67), in which several chemical substances for etching can be used by which individuals prefer to have a relationship moderately adhesive metal layer on the treated aluminum oxide Guide ceramic body. If you try to etch aluminum oxide ceramic bodies also proven substances for etching use piezoceramic bodies, then you put in Try stating that in such a way before the actual chemical metallizing pretreated piezoceramic bodies the frame with regard to the adhesive strength of the metal layer do not meet the requirements.
Gemäß der Erfindung wird daher bei einem Verfahren der eingangs angegebenen Art erfindungsgemäß bei einem Piezokeramikkörper das Ätzen mit Fluoroborsäure vorgenommen. Insbesondere bei Körpern aus Blei-Zirkonat-Titanat sowie aus Zinn-Zirkonat-Titanat als piezokeramischer Werkstoff konnten sehr gut haftende Metallschichten erzielt werden.According to the invention, therefore, in a method of the beginning specified type according to the invention in a piezoceramic body etching with fluoroboric acid. Especially at Bodies made of lead zirconate titanate and tin zirconate titanate as a piezoceramic material could adhere very well Metal layers can be achieved.
Der wesentliche Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß bei einem Ätzen von Piezokeramikkörpern mit Fluoroborsäure in dem ersten von mehreren Vorbehandlungsschritten vor dem eigentlichen chemischen Metallisieren das Aufbringen einer Metallschicht ermöglicht wird, die sich durch eine hohe Haftfestigkeit auf dem Piezokeramikkörper auszeichnet.The main advantage of the method according to the invention is that when etching piezoceramic bodies with Fluoroboric acid in the first of several pretreatment steps before the actual chemical metallization a metal layer that is characterized by a high Adhesion strength on the piezoceramic body.
Es hat sich bei dem erfindungsgemäßen Verfahren im Hinblick auf eine möglichst hohe Haftfestigkeit der Metallschicht auf Piezokeramikkörpern als besonders vorteilhaft erwiesen, wenn das Ätzen der Piezokeramikkörper mit Fluoroborsäure mit einer Konzentration von 30 bis 50% bei 20 bis 60°C für eine Zeit dauer zwischen 0,5 bis 5 Minuten vorgenommen wird.It has with regard to the method according to the invention the highest possible adhesive strength of the metal layer Piezoceramic bodies have proven to be particularly advantageous if etching the piezoceramic bodies with fluoroboric acid with a Concentration of 30 to 50% at 20 to 60 ° C for a time duration between 0.5 and 5 minutes.
Unter anderem dann, wenn mit dem erfindungsgemäßen Verfahren Piezokeramikkörper mit relativ engen Bohrungen auch im Bereich dieser Bohrungen chemisch metallisiert werden sollen, ist es vorteilhaft, wenn das Ätzen der Piezokeramikkörper unter Ultra schall-Beaufschlagung erfolgt.Among other things, when using the method according to the invention Piezoceramic body with relatively narrow holes in the area of these holes are to be chemically metallized, it is advantageous if the etching of the piezoceramic body under Ultra sound is applied.
Eine besonders hohe Haftfestigkeit von Metallschichten auf Piezokeramikkörpern läßt sich dann erzielen, wenn gemäß einer weiteren Ausgestaltung des erfindungsgemäßen Verfahrens der Fluoroborsäure 0,2 bis 35 g/1 Borsäure (H3BO3) zugesetzt werden. Anstelle des Zusatzes von Borsäure haben sich auch weitere Zusätze als sehr vorteilhaft herausgestellt. Dabei handelt es sich um Ammoniumhydrogenfluorid (NH4HF2), das mit 0,2 bis 50 g/l zuzusetzen ist, oder um Ammoniumfluorid (NH4F), das als Zusatz 0,2 bis 50 g/l ausmachen kann; auch ein Zusatz von 40%iger Flußsäure (HF) mit 0,5 bis 100 ml/l ist vorteilhaft.A particularly high adhesive strength of metal layers on piezoceramic bodies can be achieved if, according to a further embodiment of the process according to the invention, 0.2 to 35 g / 1 boric acid (H 3 BO 3 ) is added to the fluoroboric acid. Instead of adding boric acid, other additives have also proven to be very advantageous. These are ammonium hydrogen fluoride (NH 4 HF 2 ), which is to be added at 0.2 to 50 g / l, or ammonium fluoride (NH 4 F), which can make up 0.2 to 50 g / l as an additive; It is also advantageous to add 40% hydrofluoric acid (HF) at 0.5 to 100 ml / l.
Zur Erläuterung der Erfindung wird im folgenden ein besonders vorteilhafter Ätzvorgang beschrieben:In order to explain the invention, a special is given below advantageous etching process described:
Das Ätzen des Piezokeramikkörpers erfolgt mit einer 50%igen Fluoroborsäure (HBF4), der 1 g/l Ammoniumhydrogenfluorid (NH4HF2) zugesetzt worden ist. Die zu ätzenden Piezokeramik körper werden bei Raumtemperatur 1 Minute der Ätzflüssigkeit ausgesetzt, wobei während dieser Zeit eine Ultraschall-Beauf schlagung erfolgt.The piezoceramic body is etched with a 50% fluoroboric acid (HBF 4 ) to which 1 g / l ammonium hydrogen fluoride (NH 4 HF 2 ) has been added. The piezoceramic bodies to be etched are exposed to the etching liquid at room temperature for 1 minute, during which time ultrasound is applied.
