摘要:
The invention relates to a component produced powder metallurgically in the form of a valve guide or a valve seat ring having an iron-based matrix containing a mineral solid lubricant, with the matrix having a density ranging between 75 and 90% of the theoretical density, and with the mineral solid lubricant having a melting point that lies below the sintering temperature of the matrix and the remaining pore volume of the matrix of the component being melt infiltrated with the solid lubricant.
