The present invention relates to a Ti-based wire material for brazing, and
By coating the surface of the Ti-based alloy with a sheath material such as Ni or Ni-based alloy that has good brazing and plating properties,
This invention relates to a Ti-based eyeglass frame material with improved brazing strength and plating strength. Ti is a material with excellent corrosion resistance and workability.
In addition, because it is lightweight, it has recently attracted attention as a material for metal frames for high-end sunglasses. However, Ti has the disadvantage of poor brazing and plating properties, which is why it has not yet been put into practical use. In order to solve this problem, we added Cu to the surface of the Ti core material.
A Ti-based wire material with alloy clad crimped has been proposed. In the case of this type of Ti-based wire material, the above-mentioned Cu alloy is removed by etching etc. after brazing.
The aim is to utilize this technology in metal eyeglass frames, etc. However, the above-mentioned Ti-based wire material has the disadvantage of low brazing strength because a very brittle intermetallic compound is formed between Ti and Cu alloy during brazing. In view of the above-mentioned drawbacks of the conventional Ti-based wire materials, the present invention aims to provide a material for Ti-based eyeglass frames that is capable of strong brazing and has good plating properties. That is, the gist of this invention is to clad and press-bond a sheath material with good brazing and plating properties, such as a Ni-based alloy, to the surface of Ti. A more detailed explanation will be given below with reference to the accompanying drawings. The attached drawings show examples of the Ti-based eyeglass frame material according to the present invention, in which a cylindrical Ti or Ti-based alloy serving as the core material is coated with Ni or Ni or Ti-based alloy serving as the sheath material.
It is made by cradling Ni-based alloy. Here, it is desirable that the Ti-based alloy contains 90% or more of Ti. This is because if it is less than 90%, the plastic workability of the Ti alloy deteriorates, and the added components increase the specific gravity, reducing the weight reduction effect. In addition, the constituent elements included in the Ti-based alloy are:
One or two of Al, Mn, Fe, Cu, Mo, Cr, V, W, and C are useful, and when more than one is added, the total amount should be less than 10%. At this time, H 2 ,
O 2 gas is commonly included in Ti or Ti-based alloys. Further, the cladding ratio is desirably 0.7 to 0.99 for Ti or Ti-based alloy when the total volume is 1 in terms of volume ratio. That is, if the cladding ratio is smaller than 0.7, the weight increases, and if it is larger than 0.99, the strength of the cladding joint surface decreases, which is not preferred in practice. On the other hand, the Ni-based alloy preferably contains 80% or more of Ni. Component elements added to the Ni-based alloy include Cr, Cu, Fe, Ag, Si, S, Pb,
Pt, Au, Sn, Co, rare earth elements, Mo, Ml, Nb,
One or more types of Ti are useful, and when multiple types of these are added, the total amount should be less than 20%. Next, the results of experiments conducted on the weight, brazing strength, bending strength, and corrosion resistance of a Ti-based eyeglass frame material according to the present invention will be explained. First, pure Ti with a diameter of 50 mm and a length of 1000 mm has an outer diameter of 50.5 mm.
A Ni-based alloy tube with an inner diameter of 50 mm and a length of 1000 mm was placed over the tube, and this was extruded using a hot isostatic extruder at approximately 7000°C to produce a wire rod with a diameter of 10 mm. Further, this wire was annealed at about 600 to 700°C to soften it, and then cold drawn to a diameter of 5 mm. Furthermore, the wire was annealed again at the above temperature and cold drawn to a diameter of 2.6 mm.
A Ti-based wire material was prepared. The weight, brazing strength, bending strength, and
The results of experiments conducted on corrosion resistance are shown in the table below.

Sodium chloride 9.8 g/ Urea 1.7 g/ Glucose 0.2 g/ Lactic acid 0.8 cc Sodium sulfide 0.8 g/ Aqueous ammonia 0.02 g/ Water remaining Brazing strength is determined by making eyeglass frames using the materials shown in the previous table. , the breaking strength was measured when the bridge portion and rim portion were peeled off. In addition, bending strength was determined by fixing one end of the temple of an eyeglass frame with a thickness of 0.9 mm and width of 3.5 mm, setting the span to 45 mm, and applying a load to the other end using a cantilever type, resulting in a permanent strain of 1 mm displacement. The load at that time was measured. As is clear from the above experimental results, this invention
Ti-based eyeglass frame materials are lightweight, have high brazing strength, and have excellent corrosion resistance against sweat. Furthermore, the bending strength of a Ti-only structure is too low and insufficient for eyeglass frames, but this invention improves it to an appropriate value, so it is almost as good as the conventionally used nickel silver or Ni alloys. It is now equally usable. Furthermore, since Ni or Ni-based alloy is clad and crimped on the surface, it has excellent plating properties. Therefore, since the Ti-based eyeglass frame material of the present invention has the above-mentioned effects, it has properties most suitable for eyeglass frames.
