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 9):
Method according to  claim 6 , wherein after sintering of the powder, densification of the part, or assembly of the two parts by the spark plasma sintering apparatus SPS method, the sintered powder, the densified part, or the assembly of the two parts is cooled, preferably to the ambient temperature, and the cooled sintered powder, the cooled densified part, or the cooled assembly of the two parts is recovered.
