The present application relates to iron based glass forming alloys and their manufacture in powder, cored wire and stick electrode form to produce feedstock for a wide variety of weld overlay hardfacing application techniques. The alloys when welded form structures which are extremely hard and correspondingly extremely wear resistant. The novel approach of these alloys allow the replacement of conventional high hardness and wear resistant hardfacing alloys which are often composite materials made up of a binder and hard particles such as carbides, borides, borocarbides, nitrides, etc.
L'invention concerne des alliages à base de fer pouvant se vitrifier et leur fabrication sous forme de poudre, de fil enrobé et d'électrode enrobée pour produire une charge utilisée dans une gamme étendue de techniques d'application de rechargement dur pour recouvrement de soudure. Les alliages soudés forment des structures extrêmement rigides et, de ce fait, extrêmement résistantes à l'usure. L'amélioration apportée à ces alliages permet de remplacer les alliages de rechargement dur très rigides et très résistants à l'usure traditionnels qui sont souvent des matériaux composites constitués d'un liant et de particules dures telles que des carbures, des borures, des borocarbures, des nitrures, etc.
