Abstract

L'invention concerne un procédé pour le revêtement d'une surface de substrat monocristallin d'une pièce, comprenant un alliage monocristallin, par un matériau de revêtement, la surface à revêtir étant polie et le substrat étant transféré dans une chambre à vide. L'ensemble du substrat y est chauffé de manière externe à des températures qui correspondent au moins à la moitié de la température de fusion du substrat, en °C, mais qui se situent sous le point de fusion du substrat. Le matériau de revêtement est ensuite appliqué sur la surface à revêtir sous forme de poudre au moyen d'une pulvérisation par plasma sous vide, une poudre présentant une grosseur moyenne de particule dans la plage de 10 à 100 µm étant utilisée. La pression de travail se situe entre 1 et 200 mbars et un mélange argon/hydrogène est utilisé comme gaz de travail. De ce fait, au moins une zone, qui présente la même direction d'orientation monocristalline que celle du substrat sous-jacent, est générée dans la couche appliquée directement à l'interface du matériau de revêtement et de la surface de substrat polie.
