Palavras-chave:
Desgaste Microabrasivo, Intermetálicos, Aluminetos de ferroResumo
O propósito deste trabalho é pesquisar a influência do tempo de ensaio (t) e da concentração de lama abrasiva (C) sob o comportamento ao desgaste microabrasivo de uma liga de aço contendo aluminetos de ferro. Ensaios “ball-cratering” foram conduzidos sob a liga fabricada Fe-30Al-6Cr (at.%), junto a uma esfera de aço AISI 52100 e lamas abrasivas preparadas com óxido de alumínio (Al2O3) + água. Diferentes condições de ensaio foram estabelecidas e os resultados mostraram que o tempo de ensaio e a concentração da lama abrasiva influenciaram as atuações dos modos de desgaste microabrasivo e o volume de desgaste (V), sendo V proporcional à t e C (V (t,C)).
