本発明は、腕時計外装のロウ付け方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for brazing the exterior of a wristwatch.

方法とは言い難い。 For watches, the glass rim is made separately,
The structure combined with the torso is useful in terms of design. Although the above-mentioned glass edge and body are generally bonded together using an organic adhesive, it is difficult to say that this is a reliable method because the adhesive strength of the organic adhesive deteriorates over time.

点より不満足である。 FIG. 1 shows an exterior structure in which the glass edge and body are bonded together using an organic adhesive. The conventional method of joining the glass edge and body using organic resin packing shown in Figure 2 has a high bonding force and is effective as a waterproof structure, but is unsatisfactory because it cannot accommodate designs with thin shapes and narrow edges. It is.

上記金属材料の再結晶が進まない850℃以下の温
度域でのロウ付けは、ロウ材の流れ性が悪いこと
から極めて困難である。 Joining parts together by brazing is useful because it has high long-term reliability in terms of joint strength and can minimize the space required for joining compared to other methods. However, since both Stellite and cemented carbide, which are often used in watches, contain a large amount of Cr, a thermally stable oxide film is formed on the surface when heat treated in a vacuum or hydrogen atmosphere.
Brazing in a temperature range of 850° C. or lower, where recrystallization of the metal material does not proceed, is extremely difficult because the flowability of the brazing material is poor.
1100℃以上の温度域でのロウ付けは、上記材料

ラス縁と胴との接合部近傍の角部外表面について
品質よく行なうことは極めて難かしい。 Brazing in a temperature range of 1100°C or higher has better solder flowability on the above-mentioned material than in the low-temperature range, and is easier to work with, but it is difficult to perform brazing at a temperature of 1100°C or higher, due to recrystallization and recovery of the material that occurs at the same time. , changes occur in the surface, and the surface finish quality before brazing cannot be obtained after brazing. Furthermore, it is extremely difficult to perform a finishing polishing process on the outer surface of the corner near the joint between the glass edge and the body with good quality after brazing and joining.

的困難度も高い。 When a coating of TiN or TiN+TiC is formed on either the glass edge or the body by the CVD method or the PVD method, partial coating treatment is performed after the brazing bonding and polishing finishing process is completed, such as resist coating. This requires a heavy workload and is highly technically difficult.

とすることに有る。 An object of the present invention is to make it possible to create a watch exterior structure that uses Stellite or a superhard material and has a two-piece structure of a glass rim and a body by brazing and joining both parts in a completed shape and a completed surface state. At the same time,
The object of the present invention is to enable an advantageous waterproof exterior structure that has not been possible hitherto in a watch exterior using a superhard material.

て拡散焼鈍を施す事により行なつた。 In the present invention, we aim to improve the brazing properties of stellite and cemented carbide, which have a high Cr content and a small amount of metal phase and are suitable for brazing, in the temperature range of 850°C or less by brazing the alloy surface. The specimen was covered with a metal having excellent properties and diffusion annealed at 800°C to 1150°C for 1 hour in vacuum.

浄な表面を露呈することを考慮してAu−Pd、Ni
−Pd、Au−Ni等が選ばれた。 The metal coated on the surface of the material has sufficient corrosion resistance in the usage environment of the watch case, and also diffuses into the metal phase in the material after annealing, creating a continuous layer between it and the base material. Au-Pd, Ni was used in consideration of the fact that the oxide coating formed on the surface during processing at room temperature easily dissociates in a vacuum below 850℃ or in a hydrogen or nitrogen atmosphere, exposing a clean surface.
−Pd, Au−Ni, etc. were selected.
上記ロウ流れ性改良のための金属被覆層は、ロ
ウ材の流れ出しが、接合品の外観品質を損なわな
い様に、接合面のみに限定することが必要であ

便であり、十分の目的を達することができる。 The metal coating layer for improving the flowability of the solder must be limited to only the joint surfaces so that the flow of the solder material does not impair the appearance quality of the joined product. The plating method is a simple method for coating the material with the metal, and can fully achieve the purpose.

択が必要である。 It is necessary to select a brazing material that has a brazing temperature of 850°C or less, can be formed into a wire shape, does not evaporate components during brazing, and has excellent corrosion resistance.

満足である。本発明は、接合後の組合せ精度を得

る事を特徴の一つとした。 In joining the glass edge and case of a watch exterior, high dimensional accuracy after brazing is required, so the conventional method of sandwiching a brazing material between the joined parts is unsatisfactory. One of the features of the present invention is that a space for installing a brazing material is provided in a part of the joint surface for the purpose of obtaining precision in combination after joining.
