Abstract

L'invention concerne un procédé de revêtement de composants soumis à l'usure. Les composants sont revêtus d'une couche de métal dur par application par métallisation au pistolet à haute vitesse d'un métal dur pulvérulent composé d'au moins un matériau dur et d'un liant sur les composants. On utilise comme matériau dur du carbure de chrome.
