Embodiment 1

[0060] An amorphous alloy spectacle frame of this embodiment is made of a zirconium-based amorphous alloy, and the zirconium-based amorphous alloy is composed of atoms in the following atomic percentages:

[0061] Zr 52.5%

[0062] Ti 5%

[0063] Cu 17.9%

[0064] Ni 14.6%

[0065] Al 10%.

[0066] The specific preparation method of the amorphous alloy spectacle frame is to prepare spectacle frames by vacuum suction casting using zirconium-based amorphous alloy Zr52.5Ti5Cu17.9Ni14.6Al10 under the protection of vacuum and nitrogen. It is 1400MPa, the elastic limit is 2%, and the Vickers hardness is 530. After 336 hours of salt spray test, the surface of the spectacle frame is still good without corrosion. In this example, the nickel release amount of the spectacle frame prepared by using the zirconium-based amorphous alloy Zr52.5Ti5Cu17.9Ni14.6Al10 is 0.015 mg / cm 2 / week, the nickel release is equivalent to 1 / 10 of the nickel release of spectacle frames made of stainless s...

[0069] An amorphous alloy spectacle frame of this embodiment is made of a zirconium-based amorphous alloy, and the zirconium-based amorphous alloy is composed of atoms in the following atomic percentages:

[0070] Zr 48%

[0071] Ti 8%

[0072] Cu 22%

[0073] Ni 13%

[0074] Al 9%.

[0075] The specific preparation method of the amorphous alloy spectacle frame is to prepare the spectacle frame by using the zirconium-based amorphous alloy Zr48Ti8Cu22Ni13Al9 under the protection of a vacuum state and helium through the belt throwing method. The strength of the prepared spectacle frame is 1500MPa, and the elastic limit is 2.2%, the Vickers hardness is 550, and the surface of the spectacle frame is still good without corrosion after 380 hours of salt spray test. In this example, the nickel release amount of the spectacle frame prepared by using the zirconium-based amorphous alloy Zr48Ti8Cu22Ni13Al9 is 0.005 mg / cm 2 / week, the nickel release amount is equivalent to 1 / 10 of th...

Abstract

The invention relates to the technical field of amorphous alloy application, particularly to an amorphous alloy spectacle frame and glass and a production method thereof. The amorphous alloy spectacle frame is made of Zr-based amorphous alloy, has a strength of 1400-2300 MPa, an elastic limit of 2-2.5%, a Vickers hardness of 530-600 and a nickel release quantity of 0.005-0.015 mg/cm2/week, and is smooth in surface without corrosion after bearing a salt spray test for 336-480 hours. Due the fact that the amorphous alloy spectacle frame and glass is low in nickel release quantity during usage, a wearer can avoid any anaphylactic reactions during long-term wearing. Besides, the production method of the Zr-based amorphous alloy spectacle frame has the advantages of being simple in production process, high in production efficiency and low in production cost; the produced amorphous alloy spectacle frame has the advantages of being long in service life.

Description

technical field [0001] The invention relates to the technical field of application of amorphous alloys, in particular to an amorphous alloy spectacle frame, glasses and a preparation method. Background technique [0002] Glasses are prone to long-term contact with sweat and exposure to a humid environment during use, thus easily causing corrosion or rusting. In addition, the glasses in the prior art have the problem of a large amount of nickel released. Nickel is an element that can easily cause contact allergies. Nickel is released by some nickel-containing materials and absorbed by the skin after long-term contact with the skin, which can cause allergies to some individuals; further exposure to soluble nickel salts can cause national contact allergies. According to statistics, 20% of people have obvious allergic reaction symptoms to nickel. [0003] Glasses in the prior art, such as glasses made of titanium alloy or stainless steel, will release nickel, and the amount o...
