HIGHLY THERMALLY CONDUCTIVE VALVE SEAT RING |
摘要 |
The invention relates to a powdermetallurgically produced valve seat ring having a carrier layer and a function layer. It is the objective of the invention to provide a valve seat ring of the kind mentioned above that offers significantly higher thermal conductivity properties. To achieve this objective and based on a valve seat ring of the kind first mentioned above the invention proposes that the carrier material of the carrier layer has a thermal conductivity higher than 55 W/m*K at a total copper content ranging between >25 and 40% w/w. |
