Definitions
- the invention relates to a heat-resistant bearing material made of an austenitic iron matrix alloy with a sufficient to achieve a solid lubricating effect on its bearing surfaces content of sulfur, one to achieve a
- High-performance materials in particular materials for bearing elements, such as
- turbochargers or in exhaust gas recirculation systems for regulating the
- the breakthrough into the interior of the turbocharger or the exhaust gas recirculation system is usually at the same time the storage of the adjustment.
- the bearing elements are in direct contact with the exhaust gas, allowing temperatures up to 950 ° C at the
- a heat-resistant bearing material which consists of an austenitic iron matrix alloy with a, to achieve a
- Solid lubricating effect at its bearing surfaces sufficient sulfur content and in a proportion of 1 to 6 wt .-% of one or more of the alloying elements tungsten (W), cobalt (Co), niobium (Nb), rhenium (Re), molybdenum (Mo), tantalum ( Ta), vanadium (V), hafnium (Hf), yttrium (Y), zirconium (Zr) and / or comparable refractory alloying elements composed. Due to the high lubricity of the sulfides in combination with the austenitic matrix and the high creep, corrosion and oxidation resistance of this material is used as a bearing material in turbochargers in combination with gasoline engines in an advantageous manner.
- this bearing material is functionally reliable for use at high temperatures, preferably at temperatures above 600 ° C, and more preferably at temperatures above 850 ° C. This means that in particular the properties in the high-temperature range stand in the foreground with this material. In a temperature range below 400 ° C, however, such bearing materials show increased wear.
- Object of the present invention is to provide a bearing material, in particular for turbocharger or exhaust gas recirculation systems, the high temperature range, ie up to 950 ° C, but also in a temperature range below 400 ° C, the required properties, in particular a low wear.
- the object is achieved by a heat-resistant bearing material made of an austenitic iron matrix alloy with a to achieve a solid lubricating effect
- the bearing material of the invention combines the required properties, namely, that this material both in the high temperature range at temperatures above 850 ° C and in the lower temperature range, i. at temperatures ⁇ 400 ° C, shows only a slight 90 wear against various counter-rotating materials.
- the high-temperature range has been the focus of development, so that increased wear could occur in the lower temperature range.
- the invention is based on the general idea to provide a proportion of sulfur in a size which can form necessary for a lubricating effect sulfides within the alloy, and to provide a proportion of carbon in a size by which necessary for a reduction in wear carbides can form within the alloy.
- Carbon as an alloying ingredient precipitates out as fine carbon particles to improve the solid lubricating properties, or acts as an auxiliary to form carbides or intermetallic compounds
- the combination according to the invention of an austenitic matrix with sulfidic solid lubricants and a wear-resistant phase formed by carbides has succeeded in significantly increasing the wear resistance in the lower temperature range improve without losing the good wear and creep properties in the upper temperature segment.
- valve seat rings in the temperature range up to 450 ° C is common.
- the proportion of sulfur is at least 0.2 wt .-% and the proportion of carbon at least 0.8 wt .-% and at most 2.0 wt .-%. In fact, namely, from a carbon content of 0.8 wt .-%, the
- preferred carbides are formed in an iron matrix, which improves solid lubricating properties, wear resistance and mechanical strength.
