PIECE COMPOSITE CERAMIC IMPROVED METAL MATRIX, RESISTANT TO WEAR, CAKE FOR CERAMIC PIECE CERAMIC METAL MATRIX COMPOSITE MANUFACTURING METHOD THEREOF, AND CYLINDER MILL COATING COMPOSITE PANEL WITH A PIECE CERAMIC METAL MATRIX.

摘要

A ceramic composite wearing part comprises a wear part formed by a ceramic pad impregnated with a metal. Gelette the ceramic comprises ceramic grains comprising alumina and carbide grains. The inclusion of carbide grains reduces wear. Preferably, the grains comprising alumina include alumina, zirconia and titanium oxide, or alumina is preferably present in an amount of 30 to 65%, zirconia in an amount of 30 to 65% and titanium oxide in an amount of 1 to 7%, all percentages being by weight of the grains. Preferably, the ceramic wafer further comprises a fine ceramic powder, preferably in the range of 1 to 4% by weight of the grains.
