1 049 981 (S 47«29 VI/48 b) . '
Die Erfindung richtet sich auf elektrische Heizkeilgeräte zum Schweißen, Schneiden oder Formen von
thermoplastischen Kunststoffen, die im Kerii aus Kupfer bestehen und an der Arbeitsfläche mit einer
oberflächenglatten Deckschicht entweder aus Metall, vorzugsweise aus Nickel, oder aus Polytetrafluorethylen
versehen sind.
Die Form eines bisher meist auswechselbaren Heizkeiles kann sehr verschieden sein, so wie. es die jeweilige
Befund Verarbeitung eines thermoplastischen Kunststoffes erfordert.
Beim Schweißen, Schneiden und Formen von thermoplastischen Kunststoffen, insbesondere von Polyvinylchlorid
(PVC), entstehen durch den thermischen Verfall des Kunststoffes Säuredämpfe, welche die bisherigen
Heizkeile aus Kupfer sehr stark angreifen und binnen kurzem zu starken Anfressungen führen. Wenn
aber die Flächen des Heizkeiles nicht mehl· glatt sind, lassen sich keine sauberen Kunststoffverarbeitungen
mehr durchführen.
Silber an Stelle von Kupfer für die Heizkeile zu verwenden, bringt keinen Vorteil, da auch Silber von
den Säuredämpfen angegriffen wird. Abgesehen davon, daß Silber wesentlich teurer als Kupfer ist.
. Um die schädliche Einwirkung der Säuredämpfe auf den jeweils in Gebrauch befindlichen Heizkeil und
das Absetzen von Rückständen von an der Oberfläche der Heizfläche anhaftendem verkohltem PVC-Material
an der frischen Bearbeitungsstelle und die hierbei auftretenden Verfärbungen zu vermeiden, hat man bereits
den aus Kupfer bestehenden Kern des Heizkeiles an der Arbeitsfläche mit einer oberflächenglatten Deckschicht
entweder aus Metall, vorzugsweise aus Nickel, oder, auch aus Poly.tetrafluoräthylen,' das- unter dem
Handelsnamen Teflon bekannt ist, versehen.
Es hat sich aber als nachteilig erwiesen, daß. sich diese Deckschichten nur sehr schwer völlig porenfrei'
aufbringen lassen. Auch fehlt den Deckschichten eine genügend gute Haftgrundlage, so daß sie oft schon
nach kurzer Betriebszeit zunächst an einzelnen Stellen und später ganz abblättern. Diese Erscheinung
rührt daher, daß der Sauerstoff der Luft an fehlerhaften Stellen durch die Deckschicht hindurchtreten
kann und Anlaß zur Korrosion des Kupferkernes ist. Da aber Kupferoxyd voluminöser und keine Haftgrundlage
für die Deckschicht ist, bläht diese an den porösen Stellen in zunehmendem Maße auf, bis die
Deckschicht dann schließlich abblättert.
Das Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine dauerhafte oberflächenglätte
Deckschicht, sei es durch Vernickeln oder diirch Überziehen des Kupferkernes mit Polytetrafluorethylen, zu
erhalten, so daß der HeizkeiJ nicht mehr unbedingt auswechselbar zu sein braucht, weil die Forderung

erfüllt ist, daß die oberflächenglatte Deckschicht sich im Betrieb nicht verändert und immer glatt und sauber
»5 bleibt.
Die .Lösung des Problems liegt in der Erhöhung der Haftfestigkeit der Deckschicht, und die Erfindung
kennzeichnet sich durch die Verwendung einer hafterhöhenden Zwischenschicht aus Aluminiumbronze,
die durch Eindiffundieren von Aluminium in den Kupferkern hergestellt wird.
1 Das Eindiffundieren von Aluminium ist als Alitieren an sich bekannt, und zwar auch an auswechselbaren
Lötspitzen für Lötkolben. Hierbei wird aber die S5 Lötspitze selbst, die zum Löten verzinnt wird, nicht
alitiert, während nach der Erfindung gerade der Heizkeil, mit dem das· Schweißen, Schneiden oder
Formen erfolgt, an seiner der "Be- und Verarbeitung dienenden Oberfläche zur. Bildung der hafterhöhenden
Zwischenschicht alitiert wird.
Am günstigsten erfolgt das Alitieren im Glühverfahren wobei die Glühung in Aluminiumpulver bei
einer Temperatur von etwa 700° C durchgeführt wird. Die Spritzalitierung ist auch möglich, wenn durch
sie eine genügend dichte Schicht aus Alumintum-' bronze hergestellt wird.
Die so hergestellte hafterhöhende Zwischenschicht aus Aluminiumbronze wirkt für den Kupferkem einerseits
als Schutzschicht, andererseits verbessert sie infolge. ihrer mikrofeinen Rauheit die Haftung der auf
" sie aufgebrachten Deckschicht, die nunmehr ohne abzublättern., auf der durch Alitieren gebildeten Zwischenschicht
unverändert gut hält und stets ihre .glätte Oberfläche behält.
