Abstract

"MéTODO DE REPARO DAS PALHETAS DE UM ROTOR DE UM COMPRESSOR DE UMA TURBINA A GáS". Um método permite o reparo de um aerofólio (20) de uma palheta de um compressor de um motor de turbina a gás. O método compreende remover o material em liga de titânio (61) ao longo dos bordos de ataque e de fuga (34 e 36) do aerofólio, e ao longo do topo radialmente externo (40) do aerofólio para respectivamente formar os chanfros do bordo de ataque, do bordo de fuga e do topo (62, 64 e 66) com cada qual definindo uma profundidade do chanfro (D~ 1~, D~ 2~, e D~ 3~) e depositar um material de solda em titânio (80) sobre os chanfros do bordo de ataque, do bordo de fuga e do topo. O método também compreende remover pelo menos algum material de solda em titânio para que se obtenham as dimensões pré desejadas de acabamento para os bordos de ataque e de fuga e para o topo radialmente externo.
