Abstract
"MéTODO DE REMOçãO DE REVESTIMENTOS CERâMICOS". A presente invenção refere-se a um método de remoção de um revestimento cerâmico (18), e particularmente materiais de revestimento de barreira térmica contendo óxido de zircónio (TBC) tais como óxido de zircónio estabilizado com óxido de ítrio (YSZ), que tenha sido intencionalmente ou não intencionalmente depositado na superfície de um componente (10). O método vincula a sujeição de um revestimento cerâmico (18) a uma solução aquosa contendo um sal de fluoreto ácido, tal como um bifluoreto de amónio (NH4HF2) ou bifluoreto de sódio (NaF2), e um inibidor de corrosão. O método é capaz de remover completamente o revestimento cerâmico (18) sem remover ou danificar o material substrato subjacente que pode incluir um revestimento aglutinante metálico (16).
