Abstract

Est décrit un procédé pour appliquer un revêtement de matériau céramique sur un substrat par projection au plasma. Le matériau à projeter, lequel est incorporé dans le jet de plasma, renferme un composé chimique dont un constituant est un élément non métallique du groupe N, C, B, ou bien des groupes principaux VI ou VII de la classification périodique, qui se décompose, au moins partiellement, dans une atmosphère inerte avant d'atteindre le point de fusion et qui est présent dans la phase solide à l'état appliqué. Dans le but d'améliorer le procédé de sorte que le composé chimique contenu dans le matériau puisse être appliqué sur le substrat sous forme stoechiométrique, c'est-à-dire non décomposée, et forme un revêtement stable, imperméable et adhérent, l'élément non métallique est incorporé dans le jet de plasma, en plus du matériau à projeter, sous une forme libre, non liée à un élément étranger.
