Title:

SLIDING MECHANISM AND FRICTION REDUCTION METHOD FOR SAME

Document Type and Number:

WIPO Patent Application WO/2012/081310

Kind Code:

A1

Abstract:

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 600-1000ppm to diesel engine oil, setting the arithmetic mean roughness of the sliding member to 2-10nm, and upon converting the Sommerfeld number viscosity to Pa·s, the speed to s-1, and the load to mean Hertzian stress (Pa), then the lubrication conditions for use are within the range of 2.12365x10-19 to 5.94509x10-19.
