Abstract
Procédé de fabrication d'un contact pontant pour appareils de coupure électriques, ce contact comportant une couche de revêtement électriquement bonne conductrice et un support en forme de cuvette. Une ébauche de poudre à deux couches, de préférence constituée par du fer comme métal de base avec revêtement en cuivre est comprimée, frittée sous atmosphère protectrice puis, après calibrage de l'ébauche, frittée une seconde fois sous atmosphère protectrice, après quoi le pressage de finition s'effectue sous la forme d'un filage en godet avec remontée de matières.
