Title:
SLIDING MEMBER AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2020029927
Kind Code:
A
Abstract:
To provide a sliding member which has characteristic such as superior hardness peculiar to ceramic material, causes only small frictional resistance even when sliding under water-lubrication conditions and sliding under non-lubrication conditions are repeated by switching power source ON/OFF or the like and is applicable for long term operation.SOLUTION: A sliding member includes a base material which consists of composite ceramic containing silicon carbide 15 to 85 mass%, boron carbide 15 to 85 mass% (therein, the sum of silicon carbide and boron carbide is 100 mass%) and a sliding layer which consists of oxide containing boron formed on at least a part of surface of the base material. Therein, the surface of the sliding layer is a sliding surface and friction coefficient of the sliding surface to be measured in conformity to JIS R 1613:2010 is 0.3 or less.SELECTED DRAWING: Figure 1A
