description 내마모성이 우수한 철기 소결 합금제 밸브 시트를 제공한다. 비커스 경도로 700∼1300HV의 경도를 갖고, 질량%로, Si: 1.5∼3.5%, Cr: 7.0∼9.0%, Mo: 35.0∼45.0%, Ni: 5.0∼20.0%를 포함하고 잔부 Fe 및 불가피적 불순물로 이루어지는 조성을 갖는 Si-Cr-Ni-Fe계 Mo기 금속간 화합물 입자를 경질 입자로서 기지상 중에 분산시키고, 기지상, 경질 입자, 고체 윤활제 입자 등을 포함하는 기지부가, 질량%로, C: 0.5∼2.0%, Si: 0.2∼2.0%, Mn: 5% 이하, Cr: 0.5∼15%, Mo: 3∼20%, Ni: 1∼10%를 포함하고, 추가로 V: 0∼5%, W: 0∼10%, S: 0∼2%, Cu: 0∼5%를 함유하며, 잔부 Fe 및 불가피적 불순물로 이루어지는 조성을 갖는 내연 기관용 철기 소결 합금제 밸브 시트로 한다. 이것에 의해, Co를 함유하지 않는 조성이어도, 경질 입자의 크랙, 깨짐의 발생을 회피하여, 내마모성의 저하를 방지할 수 있어, 종래의 Co를 함유하는 조성과 동등 혹은 그 이상의 내마모성을 갖는 밸브 시트로 할 수 있다. An iron-based sintered alloy valve seat insert for an internal combustion engine having excellent wear resistance, has a composition wherein Si-Cr-Ni-Fe type Mo-based intermetallic compound particles having a hardness of 700 to 1300 HV in terms of Vickers hardness and a composition containing Si: 1.5% to 3.5%, Cr: 7.0% to 9.0%, Mo: 35.0% to 45.0%, and Ni: 5.0% to 20.0% in terms of mass %, with a remainder being Fe and inevitable impurities are dispersed as hard particles in a base matrix phase that includes hard particles, solid lubricant particles, and contains C: 0.5% to 2.0%, Si: 0.2% to 2.0%, Mn: 5% or less, Cr: 0.5% to 15%, Mo: 3% to 20%, and Ni: 1 to 10% in terms of mass %, and further contains V: 0% to 5%, W: 0% to 10%, S: 0% to 2%, and Cu: 0% to 5%, with a remainder being Fe and inevitable impurities.
