Abstract

vela de ignição com material de eletrodo à base de platina trata-se de uma vela de ignição para um motor de combustão interna que tem um ou mais eletrodos com um material de eletrodo de uma liga à base de platina (pt). a liga inclui alumínio (al) e um ou mais metais refratários selecionado do grupo que contém níquel (ni), rênio (re), rutênio (ru), tântalo (ta), molibdênio (mo), e tungstênio (w). em pelo menos algumas das ligas reveladas, o alumínio contribui para a formação de uma cmada de óxido da alumínio (al ~2~o ~3~) sobre uma superfiície do material de eletrodo.
