Abstract
A part (10) on which a continuous coating is to be formed is put into place on one or more supports provided with a separation layer (26) made of a material that is weaker than the material of the coating to be made. A
continuity layer (24) of a component material of the coating to be made is interposed between the part and the or each support, at least in vicinity of the or each support zone. The coating (12) is formed by chemical vapor infiltration or deposition, and the part is then separated from the or each support by rupture within the separation layer (26), the continuity of the coating of the part in the or each support zone being provided by the portion of the coating that comes from the continuity layer (24) that remains in place on the part.
continuity layer (24) of a component material of the coating to be made is interposed between the part and the or each support, at least in vicinity of the or each support zone. The coating (12) is formed by chemical vapor infiltration or deposition, and the part is then separated from the or each support by rupture within the separation layer (26), the continuity of the coating of the part in the or each support zone being provided by the portion of the coating that comes from the continuity layer (24) that remains in place on the part.
Claims (14)
1/ A method of making a continuous coating over the entire surface of a part, in which the part is put into place on one or more supports and the coating is formed thereon, the method being characterized by the steps of:
- providing the or each support with a separation layer of a material that is weaker than the material of the coating to be made;
- interposing a continuity layer of a component material of the coating to be made between the or each support and the part, at least in the or each support zone;
- forming the coating by chemical vapor infiltration or deposition; and - subsequently separating the part from the or each support by rupture within the separation layer, the continuity of the coating on the part in the or each support zone being provided by the portion of the coating that comes from the continuity layer and that remains in place on the part.
- providing the or each support with a separation layer of a material that is weaker than the material of the coating to be made;
- interposing a continuity layer of a component material of the coating to be made between the or each support and the part, at least in the or each support zone;
- forming the coating by chemical vapor infiltration or deposition; and - subsequently separating the part from the or each support by rupture within the separation layer, the continuity of the coating on the part in the or each support zone being provided by the portion of the coating that comes from the continuity layer and that remains in place on the part.
2/ A method according to claim 1, characterized in that the separation layer is made of a material of flaky structure, separation between the support and the part being achieved by cleavage within said material.
3/ A method according to claim 2, characterized in that the material of the separation layer is selected from:
laminar type pyrolytic carbon; hexagonal structure boron nitride; flake graphite; or flaky structure alumino-silicates such as talc or clays.
laminar type pyrolytic carbon; hexagonal structure boron nitride; flake graphite; or flaky structure alumino-silicates such as talc or clays.
4/ A method according to any one of claims 1 to 3, characterized in that the continuity layer is formed on the or each support over the separation layer.
5/ A method according to any one of claims 1 to 3, characterized in that the continuity layer is formed locally on the part, at least over the or each support zone.
6/ A method according to claim 4 or claim 5, characterized in that the continuity layer is made of a porous material.
7/ A method according to claim 6, characterized in that the coating is made by chemical vapor infiltration with the continuity layer being densified at least partially.
8/ A method according to claim 4, characterized in that the continuity layer is of a material similar to that or the coating to be made.
9/ A method according to claim 8, characterized in that prior to chemical vapor infiltration or deposition, surface treatment is performed on the continuity layer in order to enhance bonding with the coating made subsequently.
10/ A method according to claim 9, characterized in that the surface treatment is heat treatment.
11/ A method according to claim 9, characterized in that the surface treatment is acid attack treatment.
12/ A method according to any one of claims 1 to 11, for making a continuous coating on a part made at least in part out of carbon or graphite to provide the part with protection against oxidation.
13/ A method according to any one of claims 1 to 12, characterized in that the continuous coating formed over
14 the entire surface of the part is made of a refractory ceramic material selected from carbides and nitrides.
14/ A method according to any one of claims 1 to 13, characterized in that the continuous coating formed over the entire surface of the part is made of silicon carbide.
14/ A method according to any one of claims 1 to 13, characterized in that the continuous coating formed over the entire surface of the part is made of silicon carbide.
