Abstract

resumo patente de invenção: "sede de válvula". a presente invenção refere-se a uma sede de válvula tendo resistência e resistência ao desgaste excelentes. em uma sede de válvula usando uma liga sinterizada à base de ferro, um óxido principalmente composto de tetróxido de triferro é formado através de um tratamento de oxidação na superfície e no interior da liga sinterizada à base de ferro, e a razão de área média do óxido, principalmente composto de tetróxido de triferro em uma seção transversal da liga sinterizada à base de ferro no estado antes da instalação em uma cabeça de cilindro é de 5 a 20%. preferivelmente, a liga sinterizada à base de ferro contém partículas duras formadas de pelo menos um composto de carboneto, silicietos, nitretos, boretos e compostos intermetálicos contendo um ou mais elementos selecionados dos grupos 4a a 6a da tabela periódica, e a razão de área média das partículas duras na seção transversal da liga sinterizada à base de ferro no estado antes da instalação em uma cabeça de cilindro é de 5 a 45%. 21354089v1
