Abstract

"PROCESSO PARA REMOVER MATERIAL COM SILICATO DE ALUMìNIO DE UM SUBSTRATO, E COMPOSIçõES CORRELATAS". Onde é descrito um método para remover material baseado em silicato de alumínio (por exemplo, 'CMAS') de um substrato; o material sendo tratado com uma composição aquosa contendo ao menos um ácido de fórmula H~ x~AF~ 6~ na qual A é Si, Ge, Ti, Zr, Al, e Ga; e x é de 1 a 6; o tratamento do substrato é freq³entemente conduzido por imersão em um banho aquoso; tal método sendo também muito eficiente para remover material do tipo CMAS de cavidades do substrato, por exemplo, furos de resfriamento em um componente de turbina a gás; são também descritas composições correlatas.
