Abstract

Procédé pour l'amélioration du soudage des métaux durs qui contiennent au moins l'un des liants métalliques tels que le fer, le cobalt ou le nickel, ainsi que l'un ou plusieurs carbures et/ou nitrures de titane, de zirconium, de chrome, de molybdène, de hafnium, de vanadium, de niobium, de tantale ou de tungstène, caractérisé en ce qu'avant le soudage, le métal dur est soumis à un traitement électrolytique dans une solution alcaline sous potentiel anodique
