Abstract
a. Procédé pour la combinaison d'au moins deux matériaux céramiques, en particulier de chamotte et d'oxyde d'aluminium, essentiellement pour augmenter la capacité de résistance au frottement et à la corrosion des plaques réfractaires des fermetures coulissantes des poches de coulée. b. Procédé caractérisé en ce que le premier matériau est chauffé à une température de 800 à 1400 degrés C et le deuxième matériau est chauffé à une température de 2100 à 6000 degrés C, et que ce deuxième matériau est déposé sur le premier avec une énergie cinétique de 0,5 x 10**-7 à 100 x 10**-7 joules.
