Abstract

A valve seat is provided that exhibits excellent strength and wear resistance. For a valve seat employing an iron based sintered alloy an oxidation treatment is used to form an oxide mainly composed of triiron tetraoxide on the surface and inner section of the iron based sintered alloy. Prior to the mounting of the valve seat to a cylinder head the average area ratio of the oxide mainly composed of triiron tetraoxide in a cross section of the iron based sintered alloy is 5 20%. The iron based sintered alloy contains hard particles formed from at least one of a carbide a silicide a nitride a boride and/or an intermetallic compound of one or more elements selected from groups 4a 6a of the periodic table. Prior to mounting to a cylinder head it is preferable that the average area ratio of hard particles in a cross section of the iron based sintered alloy be 5 45%.
