The present invention is directed to a means for the surface preparation of a metal or metal alloy substrate. In the process of the present invention, a stream of a mixture of flux particles and metal particles is hurled at the substrate at velocities effective for flux adhesion to the surface. The velocities of the particle stream is adjusted so that the flux particles adhere to the surface and the metal particles bounce off the surface. At higher temperatures and velocities, the metal particles are co-deposited with the flux.
La présente invention concerne une méthode de préparation de surface d'un substrat métallique ou en alliage de métaux. Dans la méthode selon l'invention, un courant d'un mélange de particules de flux et de particules métalliques est projeté contre le substrat à une vitesse suffisante pour permettre au flux d'adhérer à la surface. La vitesse du courant de particules est ajustée de telle sorte que les particules de flux adhèrent à la surface et que les particules métalliques rebondissent à la surface. A des températures et vitesses plus élevées, les particules métalliques et le flux se déposent simultanément.
