    摘要: A shaping tooling for chemical vapor infiltration of a fiber preform includes a structural enclosure formed by supports each provided with a multiply-perforated zone. Each of the supports has in its inside face an uncased zone that includes the multiply-perforated zone. The shaping tooling further includes first and second shaping mold functional elements, each present in a respective one of the uncased zones of the support. Each shaping mold functional element has a first face of a determined shape corresponding to the shape of the part that is to be made and a second face that is held facing the inside face of a support. Each functional element has a plurality of perforations and presents a number of perforations, a size of perforations, or a shape of perforations that differs from the number, the size, or the shape of the perforations present in the facing support.

    摘要: A vapor deposition device includes a reactor including a reaction chamber and an injector for injecting vapor into the reaction chamber. The device also includes a manifold for delivering vapor to the injector. The manifold includes a manifold body having an internal bore, a first distribution channel disposed within the body in a plane intersecting the longitudinal axis of the bore, and a plurality of supply channels disposed within the body and in flow communication with the first distribution channel and with the bore. Each of the first supply channels is disposed at an acute angle with respect to the longitudinal axis of the bore, and each of the supply channels connects with the bore at a different angular position about the longitudinal axis. The distribution channel (and thus, the supply channels) can be connected with a common reactant source. Related deposition methods are also described.

    摘要: An ALD coating method to provide a coating surface on a substrate is provided. The ALD coating method comprises: providing a deposition heading including a unit cell having a first precursor nozzle assembly and a second precursor nozzle assembly; emitting a first precursor from the first precursor nozzle assembly into chamber under atmospheric conditions in a direction substantially normal to the coating surface; emitting a second precursor from the first precursor nozzle assembly into chamber under atmospheric conditions in a direction substantially normal to the coating surface; removing moving the substrate under the deposition head such that the first precursor is directed onto a first area of the coating surface prior to the second precursor being directed onto the first area of the coating surface.
