Abstract

Patente de Invenção: <B>"COMPACTAçãO POR AQUECIMENTO DE PóS DE AçO"<D>. A presente invenção refere-se a um processo de preparação de corpos de pó de aço inoxidável compactados por aquecimento, de densidade elevada, compreendendo as etapas de prover uma mistura de um pó de aço inoxidável de baixo carbono, baixo oxigênio, incluindo 10 a 30% em peso de Cr, elementos de temperamento opcionais, grafite e impurezas inevitáveis, misturando-se o pó com um lubrificante de alta temperatura e compactar a mistura em uma temperatura elevada. A invenção também concerne uma composição de pó de aço inoxidável, elementos de temperamento adicionais opcionais e um lubrificante de temperatura elevada.
