Title:
INITIAL RUNNING-IN AGENT COMPOSITION AND INITIAL RUNNING-IN SYSTEM INCLUDING SAID COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/093141
Kind Code:
A1
Abstract:
The present invention provides an initial running-in agent composition suitable for forming a low-friction surface (running-in surface) on a sliding member such as a hard carbon film in a system in which water is used as a lubricant. This initial running-in agent composition 10 contains water 11 as a base lubricant, and nanodiamond particles 12. In the initial running-in agent composition 10, the water 11 content is preferably 99% by mass or higher, and the nanodiamond particle 12 content is preferably 1.0% by mass or lower.
