Abstract
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·s, the speed to s, and the load to mean Hertzian stress (Pa), then the lubrication conditions for use are within the range of 2.12365×10to 5.94509×10.
