Abstract
This invention provides amorphous state alloy with high noble metal base, the chemical composition of which is one or many of TM1(a) TM2(b)M(c): TM1=Pd, Pt, Au, one or many of the TM2=Fe, Co, Ni, Cu, Zr, Ti and Ag, one or many among M=Si, P, Al Sn, B and Ga, among which, a:45-85, b:5-40, C:10-25. The production method includes smelting a mother alloy in vacuum first, then fusing the mother alloy in an induction oven of a quick condensing device then to be sprayed to a Cu die to be poured to an amorphous state alloy rod.
Description
Technical field
The present invention relates to a kind of amorphous alloy of making jewellery and medical device that is mainly used in, special high-content precious metal-based amorphous alloy.
Background technology
From later 1970s Ln-Al-(Ni, Cu) and Zr-Al-(Ni, Cu) after series massive amorphous the succeeding in developing, amorphous alloy has caused increasing concern as a kind of type material, and it is technical to be widely used in scientific and engineering.
In metal-metalloid amorphous alloy, simple metal base and transition metal base amorphous alloy are typically arranged, Pd-Cu-Si has appearred again in addition, Pt-Cu-Si, Pd-Ni-P, Pd-Cu-Ni-P, Pt-Cu-P, a series of precious metal one metalloid amorphous alloys such as Pt-Co-Ni-Cu-P.These amorphous alloys all have higher amorphous formation ability, are applicable to electrode materials, jewellery and medical device.But they all have certain shortcoming, and the critical size that has is little, and the bullion content that has is low, and surface luster is dark, and poor toughness is restricted its range of application.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiencies in the prior art, provide a kind of can form large block amorphous, bullion content height, surface luster good brightness, the amorphous alloy that has high strength and high tenacity again simultaneously.
Technical solution of the present invention: high-content precious metal-based amorphous alloy, its concrete chemical ingredients (atom number %) is:
TM
1(a)TM
2(b)M(c)。
Wherein, TM
1=Pd, Pt, one or more among the Au;
TM
2=Fe, Co, Ni, Cu, Zr, Ti, one or more among the Ag;
M=Si, P, Al, Sn, B, one or more among the Ga;
a：45-85，b：5-40，c：10-25。
In pure precious metal, add the suitably metalloid element of (10-25at%), the composition of alloy is near eutectic composition, can reduce its fusing point significantly, shorten the distance between fusing point and the glass transformation temperature, make liquid in process of cooling, can keep the supercooled liquid state to pass through T fast
lWith T
gBetween the zone, avoid crystallization, thereby make alloy have high amorphous formation ability.But control its content range, if the content of metalloid element less than 10at% or greater than 25at% then the amorphous formation ability of alloy is reduced, even can't obtain non-crystaline amorphous metal.
Above the supercooled liquid of described precious metal-based amorphous alloy have higher thermostability, the interval Δ T of supercooled liquid (=T
x-T
g)＞50K, T
g: glass transformation temperature, T
x: Tc.Critical size Φ＞the 0.5mm of the amorphous alloy that forms, Φ are the diameter of amorphous alloy rod.
Production method of the present invention is to use the vacuum oven smelting nut alloy earlier, then mother alloy is placed the induction furnace of quick solidification apparatus to melt, and fusing back splash is cast the amorphous alloy rod to the copper mold top-pour.
The major advantage of amorphous alloy of the present invention is: bullion content height, surface luster good brightness, hardness height, be difficult for scratching, have high strength and high tenacity again simultaneously, the critical size of the amorphous alloy that forms is up to more than the 5mm, and its production technique is simple.
Embodiment
According to the chemical ingredients and the proportioning thereof of alloy of the present invention, 17 stove amorphous alloys have been smelted altogether.At first prepare burden according to the chemical ingredients proportioning of table 1, make mother alloy at vacuum smelting furnace then, place the induction furnace of quick solidification apparatus to make its fusing mother alloy, fusing back splash is cast the amorphous alloy rod to the copper mold top-pour, its thermodynamic stability of last test.
Table 1 is the chemical ingredients of embodiment amorphous alloy; Table 2 is the thermodynamic property of the part amorphous alloy rod that embodiment cast.
