Abstract

Patente de Invenção:<B>''APARELHO CALEFATOR PARA UMA OPERAçãO DE SOLDAGEM E PROCESSO PARA A MESMA''<D>. Processo de remoção de produtos de corrosão a quente da superfície de um componente exposto à condições corrosivas em temperaturas elevadas, como é o caso dos componentes da turbina, do combustor ou do aumentador dos motores de turbina a gás. O processo é particularmente adequado para a remoção de produtos de corrosão a quente dos componentes protegidos com um revestimento superficial por difusão de aluminido, quer seja um revestimento ambiente, quer seja uma camada de ligação para um revestimento de barreira térmica (TBC). As etapas de processamento do processo incluem a imersão do componente em uma solução líquida aquecida contendo ácido acético, e a posterior agitação da superfície do componente, enquando o componente permanece imerso na solução. Desta maneira, os produtos de corrosão a quente sobre as superfícies dos componentes são removidos sem danificar ou remover o revestimento superficial por difusão de aluminido. Como resultado, as regiões do componente a partir das quais foram removidos os produtos de corrosão a quente podem ser então reparadas através de um processo de aluminização adequado.
