Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は超弾性合金のろう付け方法に関する。TECHNICAL FIELD The present invention relates to a brazing method for a superelastic alloy.

方法が用いられていた。(Prior Art) Superelastic alloys have a restoring force against large deformation and are suitable for materials such as eyeglass frames. However, since brazing is difficult, a method of crimping or screwing the joint has been used.

の被膜を付けることはコスト高でもあり好ましくない。(Means for Solving the Problem) When brazing is directly performed on a superelastic alloy, the tensile strength is weak and it is not practical. When the nickel coating is applied and then brazed by sputtering or the like, the corrosion resistance of the brazed portion becomes a problem. In the present invention, the above problems are solved by forming a titanium film on a superelastic alloy base material by sputtering, ion plating, or vapor deposition and brazing using a titanium alloy brazing material. If the film thickness of titanium is less than 1 μm, most of the titanium is thermally diffused into the base material before joining depending on the brazing method, resulting in insufficient joining. Also, it is not preferable to apply a coating of 200 μ or more because it is costly.

は認められなかつた。(Example) A superelastic alloy having an outer diameter of 4 mm was set in an ion plating device, exhausted to 10 -5 Torr, titanium was evaporated by an electron gun evaporation source, and 40 V was applied to an ionization electrode to ionize titanium. Then, -200 V was applied to the superelastic alloy to form a titanium coating of 20 μm. The superelastic alloy thus obtained is
Two commercially available brazing alloys of Ti37.5%, Cu15%, Ni10%, and Zr37.5% by weight are sandwiched and butted together, and heated to 900 ° C for 20 seconds by high-frequency induction heating in an argon gas atmosphere and joined. did. When the breaking strength of this was measured by a three-point bending test, it was 44 Kgf / mm 2 , and it was judged that the strength was sufficient.
No abnormalities were found in the 48-hour artificial sweat immersion test and the 48-hour salt water immersion test.
