Abstract

"MéTODO PARA REMOVER, DE FORMA SELETIVA, OS REVESTIMENTOS DE SUBSTRATOS METáLICOS". é descrito um método para remover seletivamente um revestimento de um substrato metálico. Alumínio é difundido no substrato. O revestimento é colocado em contato com uma composição aquosa incluindo ao menos um entre um ácido apresentando a formula H<sym>XAF<sym>, e os precursores de dito ácido, A sendo selecionado do grupo que consiste de Si, Ge, Ti, Zr, Al e Ga, e x sendo de 1-6. 0 revestimento que está sendo removido e, em geral, um material de MCrAl(X). O substrato é de metal, usualmente em uma liga "superalloy".
