Abstract
A method for producing a valve seat ring via powder metallurgy may include compacting a powder mixture including 4% by weight to 16% by weight particles of cobalt to form the valve seat ring. The method may also include sintering the powder mixture after compacting the powder mixture. Before compacting the powder mixture, 80% of the particles of cobalt may have a particle diameter of approximately 4.4 μm to 17.5 μm.
