ABSTRACT:
The invention relates to a process for the production of a cerametallic composite part containing a phase rich in Al.sub.2 O.sub.3 which is permeated by a metallic phase consisting predominantly of aluminides, in which process a preform that may have been sintered and comprises at least one oxidic compound reducible by aluminium and maybe also non-oxidic compounds or elements is reacted with molten aluminium or aluminium alloy until aluminide and Al.sub.2 O.sub.3 have formed at least in the surface layer. Composite parts fabricated in this way can serve as wear-resistant or/and high-temperature-resistant components in the construction of machinery, apparatus, engines and turbines, for applications under corrosive or/and oxidizing conditions, as functional elements, especially high-performance brake elements and as electrical or magnetic functional elements.
