The invention relates to the field of methods of depositing a material on a substrate. It relates to a method of depositing, onto a substrate, a material that acts as a thermal barrier and that prior to deposition is in powder form. The 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 the powder is vaporized, the substrate being placed on the axis of the resultant plasma jet.

Method of depositing a thermal barrier by plasma torch

The invention relates to a device and method for controlling the operation of a thermal spray torch (). The inventive device and method are characterized in that an on-board camera () and pyrometer () are used to measure the properties of the jet () and the temperature of the deposit () on the part () and in that the correction to be made to supply parameters of the torch () is deduced. Furthermore, the invention is characterized in that the corrected parameters are sent to the cabinet () that controls the torch ().

Thermal spraying instrument

The invention relates to a device and a method for control of the operation of a thermal projection torch (), characterized in that the characteristics of the jet () and the temperature of the deposit () on the piece () are measured by means of a camera () and a combined pyrometer (). The correction to be made to the supply parameters of the torch () are deduced therefrom and the corrected parameters are transmitted to the unit () controlling the torch ().
