Abstract:
A die or piston of a spark plasma sintering apparatus, wherein the die or piston is made from graphite and the outer surfaces of the die or piston are coated with a silicon carbide layer with a thickness of 1 to 10 micrometres, the silicon carbide layer being further optionally coated with one or more other layer(s) made from a carbide other than silicon carbide chosen from hafnium carbide, tantalum carbide and titanium carbide, the other layer(s) each having a thickness of 1 to 10 micrometres. A spark plasma sintering (SPS) apparatus comprising the die and two of the pistons, defining a sintering, densification or assembly chamber capable of receiving a powder to be sintered, a part to be densified, or parts to be assembled. A method of sintering a powder, densifying a part, or assembling two parts by means of a method of spark plasma sintering (SPS) in an oxidising atmosphere, using the spark plasma sintering (SPS) apparatus.

Claim (Index 8):
Method according to  claim 6 , wherein during the spark plasma sintering apparatus SPS method, a sufficient pulsed electric current is applied to the powder, to the part, or to the parts, in order to raise the temperature of the powder, of the part, or of the parts to a temperature at least equal to 700\u00b0 C. or 800\u00b0 C., preferably from 700\u00b0 C. or 800\u00b0 C. to 2500\u00b0 C., more preferably from 700\u00b0 C. or 800\u00b0 C. to 1450\u00b0 C., better from 900\u00b0 C. to 1450\u00b0 C., even better from 1100\u00b0 C. to 1450\u00b0 C.
