Valve lifter |
January 2, 2007 |
| A valve lifter, in which an amorphous hard carbon film is coated at least on the surface that slides against a cam, is characterized in that the surface of a base material (substrate) has an arithmetic mean roughness of Ra 0.01 to 0.03 micrometers, and the maximum length of the scratch o |

Amorphous hard carbon film, mechanical parts and method for producing amorphous hard carbon film |
November 23, 2004 |
| An amorphous hard carbon film has low friction coefficient from the beginning of sliding, when the metal oxide is contained in the film. The adhesion of the film to the substrate is also improved due to the low temperature treatment of RF plasma enhanced CVD method. This film can be |
