Description
Das sind zwei Forderungen, die zugleich praktisch schwer zu er-
Es ist bekannt, die Gleiteigenschaften von Metallen aufeinander zu erhöhen durch Wahl von Materialien von hoher Olaboorptionsfeatigkeit oder durch Erzeugung poröser, ölaufsaugender Schichten, wobei die Wirkung darauf beruht, daß die Metulloberfläohe oder die porösen Schichten dauernd einen Sohmiermittelfilm festhalten und die, Reibung so vermindern. Dabei ist Voraussetzung, daß die ölaufsaugende Schicht möglichst porös ist, was am besten durch Ausbildung einer ziemlich grobkörnigen Struktur der Schutzschicht erreicht wird.It is known that the sliding properties of metals towards one another increase by choosing materials with high oil absorption capacity or by Creation of porous, oil-absorbent layers, the effect being based on the fact that the metal surface or the porous layers permanently have a sealing agent film hold on and reduce the friction. It is a prerequisite that the oil-absorbing Layer is as porous as possible, which is best done by forming a fairly coarse-grained layer Structure of the protective layer is achieved.
Es sind bereits Oxydschichten in dieser Richtung bekannt geworden,
und man hat auch schon Phoophatschichten zum gleichen Zwecke vorgeschlagen. Die
Schichten selbst genügten den vorliegenden Anforderungen grundsätzlich. Jedoch zeigte
sich der schwere Man-
Erfindungsgemäß wird vorgeschlagen, eine gute Polierwirkung besitzende
Schicht auf die gewünschten Flächen von außen her aufzubringen.
In der Zeichnung ist an einem Kolbenring für Brennkraftmaschinen die Erfindung erläutert.In the drawing is on a piston ring for internal combustion engines Invention explained.
Der Ring selbst ist mit 1 bezeichnet. Auf seiner Lauffläche ist eine
Schicht 2 erzeugt, die aus einem Gemisch eines Lackes und eines feinen Schleifpulvers
besteht. Über dieser Schicht 2 könnte noch ein hier nichtgezeichneter dünner Graphitüberzug
vorgesehen
Die Körnung und Härte des Poliermittels können natürlich je nach Verwendungszweck verschieden sein. Sie werden sich auch danach zu richten haben, wie die Gegenlauffläche beschaffen ist, und mit welcher Geschwindigkeit und mit welchen Drücken die Gleit beanspruohung der miteinander arbeitenden Flächen vor sich geht.The grain size and hardness of the polishing agent can of course vary depending on the intended use to be different. You will also have to depend on it, like the counter surface is, and at what speed and with what pressures the glide stress on the surfaces that work together.
