Description
One, technical field
The cadmium-free silver brazing alloy that contains indium and cerium of the present invention belongs to the brazing material of class of metal materials and field of metallurgy.
Two, background technology
Present silver solder BAg45CuZnCd, the BAg45CuZn that uses, silver content is about 45% solder in its chemical composition.Because silver belongs to precious metal material, price is comparatively expensive, and therefore, research and development have quite or similar performance, brazing material that silver content is lower again, have important economic value and realistic meaning.The cadmium-free silver brazing alloy that contains indium and cerium of this invention is promptly finished under this technical background.
Three, summary of the invention
The task of this invention provide a kind of can the welding position in brazing process and after the soldering do not have fully poisonous element cadmium, brazing property is good, to have with traditional silver content be 45% the suitable combination property of solder (BAg45CuZnCd, BAg45CuZn), silver content is lower than the brazing material of 45% (being about about 40%) again.
This invention has mainly solved following two key technical problems: 1) develop no cadmium, combination property and traditional silver content be 45% silver solder quite or similar, the silver solder of alternative BAg45CuZnCd, BAg45CuZn, by optimizing the chemical composition of " cadmium-free silver brazing alloy that contains indium and cerium ", obtained mother metal wetability, good, the brazed seam mechanical property (σ of spreadability
b, τ) good cadmium-free silver brazing alloy; 2) in cadmium-free silver brazing alloy, add an amount of indium (In) and trace tin (Sn) to reduce the fusing point of principal component alloy (Ag-Cu-Zn alloy), improve the wetability of cadmium-free silver brazing alloy on red copper, brass, carbon steel, stainless steel and nickel-base alloy simultaneously, add the crystal grain of rare-earth element cerium (Ce) simultaneously, improve the plasticity and the comprehensive mechanical property of cadmium-free silver brazing alloy with the neoteric cadmium-free silver brazing alloy of refinement.
The technical scheme that addresses the above problem is, 1), use commercially available silver, cathode copper, zinc ingot metal, tin slab, indium metal, metallic cerium, proportioning on demand adopts that conventional intermediate frequency smelting furnace is smelted, casting, by extruding, drawing, promptly obtain needed solder wire material then; 2), according to producing needs, tin slab, indium metal, metallic cerium can be smelted into alloy respectively in advance, add then in silver-copper-zinc alloy smelt, casting, by extruding, drawing, promptly obtain needed solder wire material again.
The cadmium-free silver brazing alloy that contains indium and cerium of the present invention, its chemical composition by the mass percent proportioning is: 25.0%～32.0% copper (Cu), 25.0%～35.0% zinc (Zn), 0.5%～5.0% indium (In), 0.01%～1.0% tin (Sn), 0.002%～0.10% cerium (Ce), all the other are silver (Ag).Solidus temperature at 660 ℃～685 ℃ scopes, liquidus temperature 715 ℃～735 ℃ scopes; Cooperate FB102 (QJ102) brazing flux, brazing material is following combination: when red copper-brass, brass-carbon steel, stainless steel-nickel-base alloy, the brazed seam mechanical property is respectively: σ
b=175～335MPa, τ=170～335MPa.
Adopt conventional intermediate frequency smelting furnace to smelt, cast, by extruding, drawing, promptly obtain needed solder wire material then; The neoteric cadmium-free silver brazing alloy that contains gallium and cerium is that 45% solder is an object of reference with silver content, cooperate FB102 (QJ102) brazing flux, during combinations of materials such as soldering red copper-brass, brass-carbon steel, stainless steel-nickel-base alloy, wetability, spreadability to mother metal are suitable with it, the suitable with it (σ of brazed seam mechanical property
b=175～335MPa scope, τ=170～335MPa scope).The neoteric cadmium-free silver brazing alloy that contains indium and cerium does not have the harmful element cadmium fully, has protected operator's health safety effectively, has eliminated the pollution to environment.The brazed seam mechanical performance index of solder and BAg45CuZnCd, BAg45CuZn solder are suitable, and neoteric solder is just applied at the refrigeration part production industry as the substitute of BAg45CuZnCd, BAg45CuZn solder.

Press the mass percent proportioning, its composition is: 28.0% bronze medal (Cu), and 29.0% zinc (Zn), 0.02% tin (Sn), 2.8% indium (In), 0.005% cerium (Ce), all the other are silver (Ag).
" cadmium-free silver brazing alloy that contains indium and cerium " solidus temperature that the mentioned component proportioning obtains about 685 ℃, liquidus temperature (considered experimental error) about 725 ℃, cooperate FB102 (QJ102) brazing flux, the brazed seam intensity when the soldering mother metal is following the combination is seen data in the bracket: red copper-brass (σ
b=200 ± 25MPa, τ=200 ± 30MPa), brass-carbon steel (σ
b=300 ± 25MPa, τ=300 ± 30MPa), stainless steel-nickel-base alloy (σ
b=350 ± 15MPa, τ=260 ± 10MPa).
Another technical characterstic of the present invention is, because " cadmium-free silver brazing alloy that contains indium and cerium " of the present invention is to soldering mother metal red copper, brass, carbon steel, stainless steel, nickel-base alloy all has good wettability respectively, therefore any cadmium-free silver brazing alloy that contain indium and cerium of the above-mentioned specific embodiment one to the specific embodiment 17, in soldering red copper-red copper, red copper-brass, brass-carbon steel, brass-stainless steel, carbon steel-stainless steel, carbon steel-nickel-base alloy, stainless steel-nickel-base alloy, red copper-nickel-base alloy, during different combined material (mother metal) such as brass-nickel-base alloy, combined material (mother metal) to institute's soldering all has good wetability, and soldered fitting has good comprehensive mechanical properties.
