ROCKER SHAFT WITH DIAMOND-LIKE CARBON COATING |
| 摘要 |
A rocker shaft for a valve train of an internal combustion engine, including: a substantially cylindrical outer circumferential surface; and a layer of amorphous hydrocarbon deposited on the substantially cylindrical outer circumferential surface. The rocker shaft is arranged to engage a rocker arm such that the rocker arm is at least partially rotatable about the rocker shaft. A method of forming rocker shaft for a valve train of an internal combustion engine, including: forming a substantially cylindrical outer circumferential surface; and depositing a layer of amorphous hydrocarbon on the substantially cylindrical outer circumferential surface. The rocker shaft is arranged to engage a rocker arm such that the rocker arm is at least partially rotatable about the rocker shaft. |
