The invention relates to a method for coating high temperature components (10) by means of plasma spraying. An infrared camera (20) is used to determine the thermal radiation distribution (30) of the component surface (40) and consequently the temperature distribution (70) used to adjust an operating parameter (p) in order to obtain a threshold temperature (Ts). The invention also relates to a coating device used to form a coating (14) and simultaneously control surface temperature with the infrared camera (20).
L'invention concerne un procédé de revêtement de composants haute température (10) par projection au plasma. Une caméra infrarouge (20) permet de déterminer la répartition du rayonnement thermique (30) de la surface (40) du composant et, à partir de là, la répartition de la température (70) d'après laquelle on règle un paramètre de fonctionnement (p) afin d'obtenir une température de seuil (Ts). L'invention concerne également un dispositif de revêtement permettant de produire un revêtement (14) et simultanément de surveiller la température superficielle par une caméra infrarouge (20). ________________________________________________________
