Abstract

anéis de pistão em aços-ferramenta fundidos e seu processo de fabricação, pertencente à área de anéis de pistão em aços-ferramenta para motores a combustão interna, refere-se a anéis de pistão fundidos de aços-ferramenta cuja microestrutura é constituída por matriz de martensita revenida com precipitação de carbonetos secundários m2c elou mc (m = v e/ou mo e/ou cr e/ou w) com tamanho típico entre 0,5 (mi)m e 2 (mi)m, apresentando elevada tenacidade, e por carbonetos eutéticos nbc com morfologia cúbica, fração volumétrica entre 1% e 4%, tamanho típico entre 3 (mi)m e 7 (mi)m e distribuição homogênea, e a dureza do material após revenimento situar-se entre 400 hv e 800 hv, com limites de composição química. os anéis de pistão podem ser obtidos a partir de semiacabados fundidos por diferentes processos de fundição, preferencialmente fundição em moldes de areia verde ou areia-resina, fundição em moldes cerâmicos e fundição por centrifugação, submetidos a operações subsequentes de usinagem, e as matérias primas utilizadas no processo de fundição do semiacabado podem ser sucata de aços de baixa liga, retorno de produção e ferro-ligas.
