摘要

PROVIDED IS AN IRON-BASED SINTERED BODY WITH A RUSTPROOF FUNCTION COMPRISING A LAYER CONTAINING 0.01 TO 5AT% OF INDIUM ON THE SURFACE OF THE IRON-BASED SINTERED BODY, AND THE IRON-BASED SINTERED BODY HAVING IRON AS ITS PRINCIPAL COMPONENT IS MANUFACTURED BY PERFORMING SINTERING IN A GAS ATMOSPHERE CONTAINING INDIUM VAPOR OR INDIUM. THEREBY OBTAINED IS AN IRON-BASED SINTERED BODY, AS WELL AS THE MANUFACTURING METHOD THEREOF, CAPABLE OF EASILY IMPROVING THE RUSTPROOF EFFECT WITHOUT HAVING TO HARDLY CHANGE THE CONVENTIONAL PROCESS.
