Abstract

The purpose of the present invention is to provide an iron-based sintered alloy valve seat that can be used in a DI-type internal combustion engine adapted for enhanced fuel economy, lower emissions, and higher output, the seat being highly wear-resistant across a wide temperature range. To achieve this purpose, the added amount of a solid lubricant dispersed in a base material for the iron-based sintered alloy valve seat is limited, and at least two types of hard particles of different hardness levels are dispersed in the base material, whereby high strength and self-lubricating properties are simultaneously obtained, and wear resistance is improved across a wide temperature range, even under no lubrication.
