Abstract | A system to coat a substrate includes a deposition chamber maintained at sub-atmospheric pressure, one or more arrays containing two or more expanding thermal plasma sources (14) associated with the deposition chamber, and at least one injector (13) containing orifices (15) for each array. The substrate is positioned in the deposition chamber and each expanding thermal plasma source produces a plasma jet with a central axis, while the injector injects vaporized reagents into the plasma to form a coating that is deposited on the substrate. The injector orifices are located within a specified distance from the expanding thermal plasma source to obtain generally a coating with generally uniform coating properties.
La présente invention se rapporte à un système permettant de revêtir un substrat, qui comprend une chambre de dépôt maintenue à pression sous-atmosphérique, un ou plusieurs réseaux contenant au moins deux sources plasma thermique en expansion (14) associées à la chambre de dépôt, et au moins un injecteur (13) doté d'orifices (15) pour chaque réseau. Le substrat est placé dans la chambre de dépôt, et chaque source plasma thermique en expansion produit un jet de plasma comportant un axe central, tandis que l'injecteur injecte des réactifs vaporisés dans le plasma afin de former un revêtement qui est déposé sur le substrat. Les orifices de l'injecteur sont placés à une distance déterminée de la source plasma thermique en expansion, afin que l'on obtienne un revêtement doté de propriétés de revêtement généralement uniformes. |
