Abstract
"COMPONENTE DE FERRO FUNDIDO, E, PROCESSO DE FABRICAçãO DO MESMO". Um componente de ferro fundido, por exemplo, um eixo de cames, tem uma camada resistente a desgaste formada em pelo menos uma porção da superfície mesmo, a referida camada sendo rica em carbetos primários. O ferro fundido que cerca os carbetos e no restante do componente existe uma estrutura que é substancialmente ausferrítica. é também reivindicado um processo de fabricação de um componente.
