Abstract:
1. A method of depositing, onto a substrate, a material acting as a thermal barrier, said material being in powder form prior to deposition, wherein said powder is introduced into the plasma jet of a first plasma torch and into the plasma jet of at least one second plasma torch, the first plasma torch and at least the second plasma torch being disposed in an enclosure and oriented in such a manner that their plasma jets cross, so as to create a resultant plasma jet in which said powder is vaporized, said substrate being placed on the axis of said resultant plasma jet; wherein powder that has not vaporized continues their trajectories along the axes of the first plasma jet and at least the second plasma jet, while the powder that is vaporized is entrained by a flow of gas into the resultant plasma jet.
