A method and apparatus for a continuous coating of a part may include providing a separation layer made of a material that is weaker than the material of the coating to be made. The part may be placed on one or more supports, the supports coated with the separation layer. A continuity layer 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 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, 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 that remains in place on the part.
