Die Abnutzungsfestigkeit von Kugelgraph- gu lä t eich durch eine geeignete Ioni- trierbehandlung in einem unerwarteten A- ma verbessern. Dieses Ergebnis gilt sowohl fUr eine trockene Reibungsbeanspruchung unter Notlaufbedingungen als auch fUr FlUeeigkeits- reibung. In allen untersuchten Fällen Uber- trifft die Abnutzungsfestigkeit von ioni- trierten Kugelgraphitgu -Reibflächen diejeni- ge von gehärteten bzw. eineatzgehärteten Reib- flächen bei weitem. Das von BERGHAUS entwickelte Ionitrierverfahren be- wirkt in einer Glimmentladung eine Nitrierung metallischer Oberflächen. Die auf diese Weise gebildeten Schichten zeich- nen eich unter anderem durch einen gleichmä igen Aufbau, eine verhältniemä ig hohe Duktilität und eine nur geringe Zu- nahme der Oberflächenrauhigkeit aus. Eine Ionitrierung von Kugelgraphitgu ergab bei der Sorte GGG 60 die besten Ergebnisse bezUglieh Nitrierechicht- bildung und den daraus folgenden technologischen Eigen- schaften. Durch die gleichmä ige und duktile Härtung der in den Randschichten liegenden Ferrithöfe brechen die Sphä- rolithen auch bei hoher Reibungsbeanspruchung nicht aus. Sie werden mit fortschreitender Abnutzung abgetragen und bilden dann auf der Reibfläche partiell einen dUnnen Graphit- Schmierfilm. Ähnlich ionitrierfreudig verhält eich GGG 42, während bei GGG 70 und dem vergleichsweise untersuchten Graugu GG 25 die Ionitrierung weniger wirksam ist. Untersuchungen Uber das Notlaufverhalten bei trok- kener Reibung auf AMSLER-Abnutzungsmaschinen zeigten fUr ionitrierten GGG 60 die höchste Abnutzungefeetigkeit. - 7 - Ee folgen die ionitrierten Sorten GGG 42 und GGG 70. Dabei bewahrt der ferritieche GGG 42 weitgehend den Vorteil hoher Elastizität. Die Abnutzungsfestigkeit von ionitriertem Graugu GG 25 ist etwas geringer, Ubertrifft jedoch immer noch wesentlich diejenige von gehärteten Gu proben.
