Abstract

"PALHETA DE TURBINA A GáS APRESENTANDO UM AEROFóLIO MONO CRISTALINO COM UM REPARO DO TOPO INDICADOR, E MéTODO DE REPARO". Uma palheta de turbina a gás (20) reparada apresenta um aerofólio (22) mono cristalino feito de uma primeira liga 'superailoy' a base de níquel, e um topo indicador (46) de reparo que é soldado ao topo de um aerofólio (22). O topo indicador (46) de reparo é feito de uma segunda liga 'superalloy' a base de níquel diferente da primeira liga 'superaiioy' a base de níquel, e apresentando menos que cerca de 0,15 por cento em peso do total de carbono, boro, silício, zircónio e háfnio.
