Embodiment 1～6 and comparative example 1～4

[0186] A lubricating oil composition having the composition shown in Table 1 was prepared, and the friction characteristic test shown below was carried out to obtain the friction coefficient and wear depth. The results are shown in Table 1.

[0187] In addition, DLC containing 20% ​​hydrogen was used for the coating of the DLC-coated disk.

[0188]

[0189] The coefficient of friction was measured by the following method using a reciprocating friction tester (SRV reciprocating friction tester manufactured by Optimar Corporation).

[0190] As a test piece, a DLC-coated disc (24 mm in diameter, 7.9 mm in thickness) was used, and several drops of sample oil (lubricating oil composition) were dropped thereon. The coefficient of friction was obtained under the conditions of a load of 400N, an amplitude of 1.5mm, a frequency of 50Hz, and a temperature of 100°C with a cylinder made of SCM420 (diameter 15mm, thickness 22mm) mounted on the top of the disc.

Abstract

Disclosed is a lubricant composition which contains an organic molybdenum compound that has a nitrogen (N) atom and / or an oxygen (O) atom and optionally has a sulfur (S) atom in each molecule. The sulfur content in the organic molybdenum compound is 0.5% by mass or less based on the compound. If the lubricant composition is used as a lubricant for a low-friction sliding material, the lubricant composition has an extremely low coefficient of friction. In addition, a sliding mechanism having low friction and excellent wear resistance can be obtained by combining the lubricant composition and a sliding member that has a DLC coating film on the sliding surface.

Description

technical field [0001] The present invention relates to a lubricating oil composition for low-friction sliding materials and a sliding mechanism using the same, and more specifically, to a lubricating oil combination exhibiting excellent low friction and wear resistance for low-friction sliding materials Objects and sliding mechanisms using the lubricating oil composition. Background technique [0002] In recent years, responses to environmental issues have become more important in various fields, and technological developments for energy saving and reduction of carbon dioxide emissions are advancing. For example, one of the issues concerning automobiles is the increase in fuel consumption, and technological development of lubricating oil and sliding materials is becoming important. [0003] For lubricating oils, various base oils and additives have been developed for the purpose of improving various performances. For example, the properties required for engine oils includ...
