Title
(EN) MANUFACTURE OF METALLIC ALLOYS
(FR) FABRICATION D'ALLIAGES METALLIQUES
Abstract
(EN)
A metal alloy is produced by arc melting and atomizing a composite wire consisting of a group of strands of metal wire which is such that at every cross-section the group has the required constituents of the alloy in their correct proportions. The resulting atomized metal alloy is sprayed on a substrate which is maintained at a temperature below that of the spray to promote rapid solidification of the alloy. The substrate may be stationary or moving. The method may be used to produce a metal alloy in forms including strip, sheet, tubes and billets and may be used to form metal alloy coatings on metal or ceramic articles.
(FR)
L'alliage métallique décrit est produit par fusion à l'arc et pulvérisation d'un fil composite constitué par un groupe de torons de fil métallique, qui est conçu de sorte que chacune de ses sections transversales contient les éléments constitutifs requis de l'alliage dans leurs proportions correctes. L'alliage métallique pulvérisé qui en résulte est vaporisé sur un substrat maintenu à une température inférieure à celle du jet de vaporisation, de façon à accélérer la solidification de l'alliage. Le substrat peut être fixe ou en mouvement. Ce procédé peut être utilisé pour produire un alliage métallique sous forme de bande, de feuille, de tubes et de lingots et peut être utilisé pour former des revêtements à base d'alliage métallique sur des articles en métal ou en céramique.
