SLIDE RINGS HAVING A LEDEBURITIC MICROSTRUCTURE AT THE SURFACE

A slide ring includes a main body composed of grey cast iron, wherein at least a partial region of a functional surface has a ledeburitic microstructure at the surface. A method for producing such a slide ring includes heating a functional surface of the slide ring by irradiating with high-energy ra...

Beschreibung
Zusammenfassung:	A slide ring includes a main body composed of grey cast iron, wherein at least a partial region of a functional surface has a ledeburitic microstructure at the surface. A method for producing such a slide ring includes heating a functional surface of the slide ring by irradiating with high-energy radiation, wherein the irradiation is carried out so that at least a partial region of the irradiated surface is remelted, wherein the parameters of the irradiation are selected so that at least a partial region of the functional surface has a ledeburitic microstructure after cooling.
