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 mg / cm2 / week, and is smooth in surface without corrosion after bearing a salt spray test for 336-480 hours. Due to the face of avoiding release of nickel, the amorphous alloy spectacle frame and glass is well suitable for wearers allergic to nickel. 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...
