Abstract

"COMPOSIçãO CERMET, E, MéTODO PARA PROTEGER UMA SUPERFìCIE METáLICA EXPOSTA A UM MATERIAL EROSIVO". São fornecidos cermets nos quais a fase cerâmica é selecionada do grupo que consiste de Cr~ 23~C~ 6~, Cr~ 7~C~ 3~, Cr~ 3~C~ 2~ e misturas destes. A fase ligante é selecionada de certas ligas Ni/Cr e certas ligas Fe/Ni/Cr específicas. Esses cermets são usados particularmente na proteção de superfícies de erosão a altas temperaturas.
