PISTON RING AND METHOD OF PRODUCING THE SAME |
| 摘要 |
A piston ring that may be mounted to a piston made of an aluminum alloy that slides with a cylinder liner containing Fe as a main component is disclosed. The piston ring is formed to have hard carbon coatings containing no hydrogen formed on an outer periphery and at least one side surface of the piston ring, the hard carbon coating formed on the outer periphery having no columnar structure, and the hard carbon coating formed on the side surface having a columnar structure extending in a direction intersecting with the side surface. |
