The purpose of the present invention is to provide: a sliding member having a lubricating film formed on the sliding surface thereof, and capable of exhibiting friction-reducing performance; and a friction reduction method for the same. To that end, the present invention entails coating the sliding surface with a titanium nitride-based material (for example, titanium carbon nitride, titanium nitride, or titanium aluminum nitride), adding a molybdenum dithiocarbamate with molybdenum in the amount of 600-1000 ppm to diesel engine oil, setting the arithmetic mean roughness of the sliding member to 2-10 nm, and upon converting the Sommerfeld number viscosity to Pa&#xb7;s, the speed to s, and the load to mean Hertzian stress (Pa), then the lubrication conditions for use are within the range of 2.12365&#xd7;10to 5.94509&#xd7;10.

Sliding mechanism and friction reduction method for the same

The purpose of the present invention is to provide: a sliding mechanism having a lubricating film formed on the sliding surface thereof, and capable of exhibiting friction-reducing performance; and a friction reduction method for the same. To that end, the present invention entails coating the sliding surface with chromium nitride, adding a molybdenum dithiocarbamate with molybdenum in the amount of 600-1000 ppm to diesel engine oil, setting the arithmetic mean roughness of the sliding member to 2-60 nm, and upon converting the Sommerfeld number viscosity to Pa&#xb7;s, the speed to s, and the load to mean Hertzian stress (Pa), then the lubrication conditions for use are within the range of 2.12365&#xd7;10to 5.94509&#xd7;10.
