6. Camshaft DLC Coating
Tetrahedral Amorphous carbon (ta-C) coated has been applied to gasoline engines from autumn 2006 for the first time in the
World .t

7. IMPACT WEAR MECHANISM Future Research
Though a solution by using the DLC coatings has practically
applied in the industry, nobody knows how the Impact wear mechanisms of the DLC
coating acts in low-load .
Future Research
