Title:
内燃機関用に耐疲労性を高めたピストンリング及びその製造方法
Document Type and Number:
Japanese Patent JP6289504
Kind Code:
B2
Abstract:
A piston ring (2) having increased fatigue resistance includes a plastically deformable material. The piston ring (2) has a running face (4), which is delimited at the top by an upper running face edge (3) and at the bottom by a lower running face edge (1). Compressive stresses are introduced into the upper running face edge (3) and/or into the lower running face edge (1) along at least one part of the circumference, the compressive stresses having been produced by roller burnishing.
