Revestimentos para barreira térmica: evolução e perspectivas

Abstract: Resumo Palavras-chave: Revestimento para barreira térmica; TBC; Aspersão térmica; Metal-cerâmica. Abstract: For over four decades, thermal barrier coatings, or simply TBC, have been decisive for the performance of gas turbines in aviation and aerospace, and more recently also in the performance of power generation turbines and diesel engines. Its importance overlaps the developments achieved in the area

“…This attack occurs because the YSZ is an extremely porous layer. As the equipment operates at high temperatures, deposits from the environment, including dust, sand, volcanic ash, and runway de-bris, melt and penetrate the porous structure of the TBC [4] [16] [17] [18]. Inside the TBC, the CMAS promotes a thermochemical attack, as the YSZ dissolves in the presence of the CMAS and reprecipitates with different compositions and morphology [16].…”

“…Entre os vários métodos de proteção por uso de revestimento, a Aspersão Térmica (ASP) de um material adequado sobre uma superfície pode prolongar a vida útil da peça, mantendo suas propriedades mecânicas originais, enquanto protege contra o desgaste e a corrosão [7][8][9][10][11][12][13][14][15]. Comparativamente, o processo de ASP por arco elétrico é uma solução relativamente de baixo custo, rápida e simples de ser executada, podendo ser realizada em campo [16,17].…”
