本発明は、眼鏡フレーム用複合素材の改良に係り、詳し
くは材料のクラッド接合強度が強く且つろう付特性に優
れた眼鏡フレーム用複合素材に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of a composite material for eyeglass frames, and more particularly, to a composite material for eyeglass frames that has strong cladding strength and excellent brazing properties. .
(従来技術とその問題点)
近時、眼鏡着用者の活動範囲を広げる意味やかけ心地な
どの点からレンズ、フレーム共軽量の眼鏡が要望されて
いる。(Prior art and its problems) Recently, there has been a demand for eyeglasses with lightweight lenses and frames from the viewpoint of expanding the range of activities of eyeglass wearers and from the viewpoint of comfort.
このような要望に応えようとする眼鏡フレーム用素材と
して、最近Ti又はTi合金が使用されている。Recently, Ti or Ti alloys have been used as materials for eyeglass frames to meet such demands.
しかしTi又はTi合金は、ろう付性が悪く、強い強度
を持たせる為には、高真空中或いは特殊な雰囲気の下で
ろう付を行う必要があり、この点での改善が望まれてい
た。However, Ti or Ti alloys have poor brazing properties and must be brazed in a high vacuum or in a special atmosphere in order to have strong strength, and improvements in this respect have been desired. .
その1つの手段として、第3図に示す如<Ti又はTi
合金を芯材1とし、これの外側に耐食性が良く且つろう
付性に優れた材料2、例えばNi−Cr合金、金合金、
銀合金などのいずれかがクラッドする方法が採られてい
る。As one of the means, as shown in FIG.
An alloy is used as the core material 1, and a material 2 having good corrosion resistance and brazing properties is provided on the outside of the core material 1, such as Ni-Cr alloy, gold alloy, etc.
A method of cladding with silver alloy or the like has been adopted.
しかしこの方法に依ると、Ti又はTi合金の芯材1の

料2との界面に非常に脆い金属間化合物6が生成される
ので、ろう付後この金属間化合物6の層から剥離すると
いう致命的な欠点があった。However, although this method has the advantage of preventing oxidation or nitridation of the Ti or Ti alloy core material 1 and allowing easy brazing in the atmosphere, the composite material 3 for eyeglass frames is rolled into a sheet material. 4 is made, and this plate material 4 is heated to 60 mm using a brazing material 5 such as Ag wax or Au wax as shown in Fig. 4.
When brazing in the air at 0 to 900°C, a very brittle intermetallic compound 6 is generated at the interface between the core material 1 and the outer material 2, so the layer of intermetallic compound 6 peels off after brazing. There was a fatal flaw.
(発明の目的)

2、例えばNi−Cr合金。(Structure of the Invention) The composite material for eyeglass frames of the present invention is as shown in FIG.
A core material 1 is made of Ti or a Ti alloy, and a Cu-Ni alloy is clad on the outside as an intermediate layer 7, and a material 2 having good corrosion resistance and brazing properties, such as Ni- Cr alloy.
