METHOD FOR ASSEMBLING REFRACTORY CERAMIC PARTS BY MEANS OF SPARK PLASMA SINTERING (SPS)

摘要

The invention relates to a method for assembling at least two refractory ceramic parts by means of spark plasma sintering, each of said parts having at least one surface to be assembled by means of spark plasma sintering, comprising the following steps in which: the surfaces of the parts to be assembled are brought into contact with one another with nothing added therebetween, an assembly pressure of between 1 and 200 MPa is applied to the parts, a pulsed electric current with a strength of between 500 and 8000 A is applied to the parts so as to raise the temperature thereof to an assembly temperature of at least 1300°C, the electric current and the pressure are removed simultaneously and the parts are cooled, and the assembled parts are recovered.
