Metal ceramics composites having high bonding strength wherein a metal body and a ceramics body are bonded through a bonding layer are produced by coating on the ceramic body a metallizing layer-forming composition, which forms through heat treatment with the ceramic body a metallizing layer consisting essentially of 70-90% by weight of at least one of molybdenum metal and tungsten metal, 0.5-15% by weight of manganese oxide, 0.1-10% by weight of yttrium oxide, 0.1-15% by weight of aluminum oxide and 0.1-15% by weight of silicon dioxide, heating the ceramic body and the coated metallizing layer-forming composition to form and adhere the metallizing layer on the ceramic body, applying metal plating on either or both of the metallizing layer surface to be bonded and the metal body surface to be bonded, and bonding the thus obtained ceramic body and metal body by using a brazing metal.
Metal ceramic composites having a metal body and a ceramic body bonded together through a bonding layer, said bonding layer being applied on a surface of the ceramic body and provided with a metallizing layer consisting essentially of 70-90% by weight of a metal selected from the group consisting of molybdenum and tungsten, 0.5-15% by weight of manganese oxide, 0.1-10% by weight of yttrium oxide, 0.1-15% by weight of aluminum oxide and 0.1-15% by weight of silicon dioxide.
Metal ceramic composites having a nodular cast iron metal body and a zirconia ceramic body bonded together through a bonding layer, said bonding layer being applied on a surface of the zirconia ceramic body surface and provided with a metallizing layer consisting essentially of 70-90% by weight of a metal selected from the group consting of molybdenum and tungsten, 0.5-15% by weight of magnanese oxide, 0.1-10% by weight of yttrium oxide, 0.1-15% by weight of aluminum oxide and 0.1-15% by weight of silicon dioxide, wherein a metal plating layer is provided on a surface selected from the group consisting of a surface on the metallizing layer and a surface on the nodular cast iron body, whereby said metallizing layer and nodular cast iron body are bonded by a brazing metal.
Metal ceramic composites having a nodular cast iron metal body and a yttrium oxide-containing partially stabilizer zirconia bonded together through a bonding layer, said bonding layer being applied on a surface of the partially stabilized zirconia body and provided with a metallizing layer consisting essentially of 70-90% by weight of a metal selected from the group consisting of molybdenum and tungsten, 0.5-15% by weight of magnanese oxide, 0.1-10% by weight of yttrium oxide, 0.1-15% by weight of aluminum oxide and 0.1-15% by weight of silicon dioxide, wherein a metal plating layer is provided on a surface selected from the group consisting of a surface on the metallizing layer and a surface on the nodular cast iron body, whereby said metallizing layer and nodular cast iron body are bonded by a brazing metal.
Metal ceramic composites having a metal body and a ceramic body bonded together through a bonding layer, said bonding layer being applied on a surface of the ceramic body and provided with a metallizing layer consisting essentially of 70-90% by weight of a metal selected from the group consisting of molybdenum and tungsten, 0.5-15% by weight of magnanese oxide, 0.1-10% by weight of yttrium oxide, 0.1-15% by weight of aluminum oxide and 0.1-15% by weight of silicon dioxide made by the method of:
