Abstract

The invention discloses a titanium alloy spectacle frame and a preparation method thereof. The titanium alloy spectacle frame is characterized in that titanium alloy comprises the components of metalA, metal B, the balance titanium and inevitable impurities; the metal A is metal with the melting point higher than the melting point of Ti by a range within 600 DEG C, and the metal B is metal with amelting point lower than the melting point of Ti by a range within 200 DEG C; and the metal A comprises one kind or several kinds of platinum, zirconium and hafnium, and the metal B comprises one kind or several kinds of lutetium, palladium, erbium, thulium, scandium, yttrium, iron and cobalt. The preparation method is characterized in that the titanium alloy spectacle frame is obtained through the steps of preparing intermediate alloy, preparing the titanium alloy and producing the titanium alloy spectacle frame. The titanium alloy spectacle frame produced by the method is light in weight, is firm, is good in biocompatibility with a human body, does not contain elements such as nickel which easily causes anaphylactic reaction, is good in glossiness, conforms to the public aesthetic judgment and is good in elasticity, the comfort experience is brought to a wearer, and the problem of falling off caused by large deformation can not be caused.

Description

technical field [0001] The invention relates to the field of spectacles, in particular to a titanium alloy spectacle frame and a preparation method thereof. Background technique [0002] The spectacle frame is an important part of the glasses, mainly to support the spectacle lens, and the spectacle frame with a beautiful appearance can also play an aesthetic role. Spectacle frame materials mainly include metal, plastic or resin, natural materials, etc. Metal spectacle frames require materials with certain hardness, softness, elasticity, wear resistance, corrosion resistance, light weight, luster and good color, etc. Therefore, the metal materials used to make spectacle frames are almost all alloys or used after metal surface processing. Common metal spectacle frames include white copper frames (copper-zinc alloy), high-nickel alloy frames, Monel material frames (nickel-copper alloy), pure titanium frames, memory titanium alloy frames (nickel-titanium alloy), β -Titanium a...
