Abstract

Recently, as the matters of environmental pollution, the energy exhaustion and alternative energy source have become more important issues, around industrial countries and the effort to improve fuel consumption is progressed continuously for decrease of air pollution. In an effort to improve fuel consumption for passenger cars, the study of DLC (Diamond Like Carbon) coating which is widely known to good wear characteristics come to the forefront. Therefore, in present study, it was investigated to the influence of DLC coating layer for wear characteristics with the piston ring material and then suggested to the development process for advanced automotive engine parts that showed improved wear characteristics. From these results, Finally, it will be contributed to improve the fuel consumption for passenger vehicles.
