PURPOSE:To obtain a piston ring with high abrasion resistance, excellent sliding performance and generally prolonged life by sintering powder such as carbide into grooves provided on the sliding surface of a piston ring and simultaneously bonding it to piston ring body material to form the sliding surface. CONSTITUTION:Plural grooves 5 narrower than the width of the piston ring sliding surface and deeper than 2mm are provided, and powder such as carbide is sintered into the grooves 5 and simultaneously bonded to piston ring body material 1 to form a sliding surface. The sliding surface is thus formed of high hardness abrasion resistant material, and if highly flexible general iron or steel is used as the piston ring body material 1, two-layer structure is obtained to prevent an accident caused by the breaking of a piston ring and also the piston ring four to five times more durable than the conventional rings can be obtained.
