Embodiment 1
[0014] The brazing material alloy of this embodiment is formulated according to 23wt% V, and the balance is ruthenium and unavoidable trace impurities. The content of Zn, Pb, Bi and Mg elements in the trace impurities shall not exceed 0.001%. Adopt electric arc furnace to smelt into ingots, ingots are processed by mechanical cutting or mechanical crushing, then through high-energy ball mill grinding, finally sieving, reduction, pickling to obtain the ruthenium vanadium binary alloy powder solder of the present invention, and then in H 2 Welding process test of brazing filler metal in gas furnace, its wetting and spreadability on the base metal is good, no corrosion to the base metal, the spreading area of the solder after melting is more than 4 times of the original solder placement area, the wetting angle less than 10°.
Embodiment 2
[0016] The brazing material alloy of this embodiment is formulated according to 26wt% V, and the balance is ruthenium and unavoidable trace impurities. The content of Zn, Pb, Bi and Mg elements in the trace impurities shall not exceed 0.001%. The ingot is smelted into an ingot by an electric arc furnace, and the ingot is machined or crushed by a machine, then ground by a high-energy ball mill, finally screened, reduced, and pickled to obtain the ruthenium-vanadium binary alloy powder solder of the present invention. Then in H 2 The welding process test of brazing material was carried out in the gas furnace. The wetting and spreading of ruthenium vanadium solder on the base metal is good, and there is no corrosion to the substrate. The spreading area of the solder after melting is more than 4 times that of the original solder placement area. The wet angle is less than 10°.
Embodiment 3
[0018] The brazing material alloy of this embodiment is formulated according to 40wt% V, and the balance is ruthenium and unavoidable trace impurities. The content of Zn, Pb, Bi and Mg elements in the trace impurities shall not exceed 0.001%. The ingot is smelted into an ingot by an electric arc furnace, and the ingot is machined or crushed by a machine, then ground by a high-energy ball mill, finally screened, reduced, and pickled to obtain the ruthenium-vanadium binary alloy powder solder of the present invention. Then in H 2 The welding process test of brazing material was carried out in the gas furnace. The wetting and spreading of ruthenium vanadium solder on the base metal is good, and there is no corrosion to the substrate. The spreading area of the solder after melting is more than 4 times that of the original solder placement area. The wet angle is less than 10°.
