SLIDE RINGS HAVING A LEDEBURITIC MICROSTRUCTURE AT THE SURFACE |
摘要 |
The invention relates to a slide ring, comprising a main body composed of gray cast iron (2), wherein at least a partial region (6) of a functional surface (4) has a ledeburitic microstructure at the surface. The invention further relates to a method for producing a slide ring, comprising producing a slide ring composed of gray cast iron (2), heating a functional surface (4) of the slide ring by irradiating the functional surface of the slide ring with high-energy radiation, wherein the irradiation is performed in such a way that at least a partial region of the irradiated surface is remelted, wherein the parameters of the irradiation are selected in such a way that at least a partial region (6) of the functional surface has a ledeburitic microstructure after the functional surface has been cooled. |
