Abstract

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 thereof. The spectacle frame is made of a zirconium-based amorphous alloy. The strength of the manufactured spectacle frame is 1400MPa~2300MPa, the elastic limit is 2%~2.5%, the Vickers hardness is 530~600, the nickel release is 0.005mg / cm2 / week~0.015mg / cm2 / week, and it can withstand 336 hours The surface is still good without corrosion after ~480 hours of salt spray test. Since the manufactured amorphous alloy spectacle frame and glasses release very little nickel during long-term use, the wearer will not cause any allergic reaction during long-term wearing. In addition, using the zirconium-based amorphous alloy to prepare the spectacle frame has the advantages of simple production process, high production efficiency and low production cost, and the prepared spectacle frame has the advantage of long 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] Spectacles in the prior art, such as those made of titanium alloy or stainless steel, release a large amount of nickel, wh...
