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 (Description of the field to which the invention pertains) The present invention relates to an improvement of a composite material for eyeglass frames, and more specifically, a composite material for eyeglass frames that has strong cladding strength and excellent brazing properties. Regarding.
近時、眼鏡着用者の活動範囲を広げる意味やかけ心地の
点からレンズ、フレーム共軽量の眼鏡が要望されている
。In recent years, there has been a demand for eyeglasses with lightweight lenses and frames, both to expand the range of activities of eyeglass wearers and to make them more comfortable to wear.
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.
(従来技術とその問題点)
しかしTi又はTi合金はろう付特性が悪(、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
。(Prior art and its problems) However, Ti or Ti alloys have poor brazing properties (in order to have strong strength, it is necessary to braze in a high vacuum or in a special atmosphere; Improvement was desired.
その1つの手段として第3図に示す如(Ti又はTi合

ずれかがクラ・ノドする方法が採られている。As one means for this purpose, as shown in FIG.
A method is adopted in which any one of Cu alloy, Au alloy, Ag alloy, stainless steel, etc. is crushed.
しかしこの方法に依ると、Ti又はTi合金の芯材1の
酸化或いは窒化が防げ、大気中で簡便にろう付が行える
という長所があるものの、この眼鏡フレーム用複合素材
3を圧延して板材4を作り、この板材4を第4図に示す
如<Agろう、Auろう等のろう材5を用いて600℃

2との界面に非常に脆いTi Ni、Ti Au等
の金属間化合物6が化成されるので、ろう付後にこの金
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 plate material 4. This plate material 4 is heated at 600°C using a brazing material 5 such as Ag wax or Au wax as shown in Fig. 4.
When brazing in the air at ~900°C, very brittle intermetallic compounds 6 such as Ti Ni and Ti Au are formed at the interface between the core material 1 and the outer material 2. It had the fatal drawback of peeling off from the layer.
(発明の目的)
本発明は斯かる欠点を解消すべくなされたもので、大気
中でろう付が可能で、しかもろう付強度が著しく高くそ

合素材を提供せ・んとするものである。(Purpose of the Invention) The present invention has been made in order to eliminate such drawbacks, and provides an eyeglass frame that can be brazed in the atmosphere, has extremely high brazing strength, and does not separate from the upper and outer materials. The aim is to provide composite materials for use in
(発明の構成)
本発明の眼鏡フレーム用複合素材は、第1図に示す如<
T i又はTi合金を芯材1とし、これの外側にPd
2.5〜50重量%とSi、Gaの1種もしくは2
種0.01〜10重量%を含むAg合金が中間層として
クラッドされ、この中間層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、Ni−
Cu合金、Au合金、Ag合金、ステンレス鋼などのい
ずれかがクラッドされてなるものである。(Structure of the Invention) The composite material for eyeglass frames of the present invention is as shown in FIG.
Ti or Ti alloy is used as the core material 1, and Pd is placed on the outside of this.
2.5 to 50% by weight and one or two of Si and Ga
An Ag alloy containing 0.01 to 10% by weight of seeds is clad as an intermediate layer, and a material 2 having good corrosion resistance and brazing properties, such as Ni-Cr alloy, Ni-
It is clad with Cu alloy, Au alloy, Ag alloy, stainless steel, etc.
ここで中間層としてAg合金を用いたのはろう付の際の
熱ひずみをAgが緩和するからである。The reason why an Ag alloy was used as the intermediate layer here is that Ag relieves thermal strain during brazing.
更にPdを添加するのはTiあるいは外被材とPdが優
先的に拡散結合し、特にP d −T iは脆くなく、
ろう付後の剥離が防げるからである。Pdを2.5〜5
0重量%と限定したのは2.5重量%未満ではPdが優
先結合してPd−Ti層を形成するに十分でなく、50
重量%を超えると、熱緩和材としてのAg層が少くない
熱ひずみにより剥離が生ずるからである。Furthermore, the addition of Pd causes preferential diffusion bonding between Ti or the outer cover material and Pd, and in particular, Pd-Ti is not brittle.
This is because peeling after brazing can be prevented. Pd 2.5-5
The reason why it is limited to 0% by weight is that if it is less than 2.5% by weight, Pd will not be able to preferentially combine and form a Pd-Ti layer.
This is because if it exceeds the weight percentage, the Ag layer as a thermal relaxation material will peel off due to considerable thermal strain.
更にSi、Gaを1種または2種添加する理由は、ろう
付温度を上げすぎた場合のP d −T i層の異常成
長を妨げ剥離が生ずるのを防止するためである。これは
TiとSiまたはGaがPd−Tiより優先的に結びつ
き非常に薄いTi−3i層またはTi−Ga層を形成し
、これがPd−Tiの成長を抑えるからである。St、
Gaの1種または2種の量を0.01〜10重量%とし
たのは0.01重量%未満ではその効果がなく、10重
量%を超えると加工困難となるからである。Furthermore, the reason why one or two types of Si and Ga are added is to prevent abnormal growth of the P d -Ti layer and to prevent peeling if the brazing temperature is raised too much. This is because Ti and Si or Ga combine preferentially over Pd-Ti to form a very thin Ti-3i layer or Ti-Ga layer, which suppresses the growth of Pd-Ti. St.
The reason why the amount of one or two types of Ga is set to 0.01 to 10% by weight is because if it is less than 0.01% by weight, there is no effect, and if it exceeds 10% by weight, processing becomes difficult.
