Abstract
A piston ring exhibiting particles capable of wear resistance on its shoulder is produced by producing a melt of the base materials of a metal material, adding ceramic particles to the melt, pouring the melt into a prefabricated mold and cooling the melt. During cooling, the mold is aligned such that the ceramic particles gather on at least one of the piston ring shoulders.
