Abstract:
1. An installation for depositing, onto a substrate, a material acting as a thermal barrier, said material being in powder form prior to deposition, the installation comprising: an enclosure having said substrate disposed therein, a first plasma torch, which includes a first anode and a first cathode, and at least one second plasma torch, which includes a second anode and a second cathode, and is disposed in said enclosure in such a manner that when said powder is introduced into the first plasma jet of said first plasma torch at the end of said first plasma torch from which said first plasma jet is ejected and into the second plasma jet of at least said second plasma torch at the end of said second plasma torch from which said second plasma jet is ejected, the first plasma jet of said first plasma torch and the second plasma jet of said second plasma torch cross at an intersection, such that particles of the powder in the first and second plasma jets that do not vaporize at the intersection continue moving through the intersection along respective trajectories of the first and second plasma jets and do not collide with said substrate while moving along the respective trajectories, thereby creating a resultant plasma jet in which said powder is vaporized, said substrate being placed on the axis of said resultant plasma jet.
