PROBLEM TO BE SOLVED: To provide a low friction sliding member with which the friction between a counterpart member and itself can be lowered even if the surface roughness of a sliding surface is large. SOLUTION: The low friction sliding member 1 is constituted of a base material 11 and a sliding layer 21 which is formed on the sliding surface side of the base material 11 and brought into contact with the counterpart member formed in a sliding state. The sliding layer 21 is formed from amorphous carbon containing carbon as a main component, >30 to <50 atomic% hydrogen, and 1.5-20 atomic% silicon, where carbon having sp<SP>2</SP>-hybrid orbital is contained in an amount of 40-70 atomic% in the carbon. As the low friction sliding member 1 has a soft sliding layer 21, a sliding surface 21f can be made smooth by sliding even when the surface roughness of the sliding surface 21f is large. A wear resistant layer 22 formed from amorphous carbon containing hydrogen in an amount lower than that of the hydrogen contained in the amorphous carbon of the sliding layer 21 may be provided between the base material 11 and the sliding layer 21. The wear resistant layer 22 imparts a high wear resistance to the soft, low friction sliding member 1. COPYRIGHT: (C)2007,JPO&INPIT |
