The invention discloses a piston ring comprising a piston ring substrate.
The piston ring substrate comprises at least 50 volume %, of at least one
intermetallic alloy, based on the total volume of the wear-resistant
composition. The invention further relates to a piston ring comprising a
wear-resistant composite composition and a piston ring coating comprising
a wear-resistant composition, the wear-resistant composite composition
comprising a ceramic compound.
