The invention discloses a
metal-based material for the preparation of a crystallizer or a
tuyere and belongs to the technical field of
surface engineering. According to the
metal-based material, a
transition layer is innovatively arranged between a Cu or Cu
alloy matrix and a high-abrasion-resistance working layer by the adoption of a metallurgical bonding method, and made of at least one of pureCo
metal, pure Ni metal, pure Cr metal, pure Cu metal, pure Mo metal, pure Ag metal and a NiCr or MCrAlY
alloy; through the
transition layer, the functions of improving the
laser absorption rate, lowering the matrix heat
conductivity, and lowering the
dilution rate can be achieved; due to the existence of the
transition layer, the thickness of the working layer can be adjusted within a range of 0.01-3 mm and the formation of surface cracks can be avoided; furthermore, the ratio of the thickness of the transition layer to that of the high-abrasion-resistance working layer is 1:(1-3), so that the perfect bonding of the transition layer and the high-abrasion-resistance working layer can be guaranteed within the ratio range; the formation of a high-abrasion-resistance
coating or
coating product which is free of surface cracks and subjected to metallurgical bonding on the Cu or Cu
alloy matrix can be improved; the reliability of the crystallizer or the
tuyere can be improved; and the service life of the crystallizer or the
tuyere can be prolonged.
