Description
【発明の詳細な説明】
本発明は、ＴＩＮを主成分とする高硬度・高耐食性、及
び金色色調を呈する硬質時計用外装部品に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hard exterior part for a watch that is mainly composed of TIN and exhibits high hardness, high corrosion resistance, and a golden color tone.
ここで、時計用外装部品とは、時計胴、裏ブタ、ガラス
緑、リューズ、時計バンド等のことを呼び、本発明では
特に、時計側について詳述する。最近、超硬合金の時計
ケースへの応用が広く行なわれているが、超硬合金の色
調は、殆んどが、光輝色であり、金色色調を呈するもの
は、ＴａＣ，ＴＩＮぐらいである。Here, the exterior parts for a watch refer to the watch body, case back, glass green, crown, watch band, etc., and the present invention will specifically describe the watch side in detail. Recently, cemented carbide has been widely applied to watch cases, but most of the cemented carbide metals have a bright color, and only TaC and TIN exhibit a golden color.
ところが、ＴａＣは、Ｔａの価格が、非常に高く時計ケ
ースへの応用にもかなり無理が生じてきた。またＴＩＮ
は、靭性に劣り、時計ケースとしては実用に供さないも
のである。However, the price of Ta is extremely high, making it difficult to apply TaC to watch cases. Also TIN
is inferior in toughness and cannot be used practically as a watch case.
このため金色色調を呈し、安価で鞠性のある超硬時計の
出現が望まれていた。本発明は、こうした欠点を除去す
るもので、ＴＩＮを主成分とし、その他適当な元素を含
有することにより、金色色調を呈し、且つ安価で靭性の
ある超硬時計の製造を可能ならしめている。For this reason, there was a desire for a carbide watch that had a gold tone, was inexpensive, and had good ballistic properties. The present invention eliminates these drawbacks, and by using TIN as a main component and containing other appropriate elements, it is possible to manufacture a carbide watch that exhibits a golden tone, is inexpensive, and has toughness.
これまでＴＩＮ系の超硬合金は、機械的強度を向上させ
るため、鉄系金属等を含有させることにより、その効果
を得ていたが、靭性を十分にもたせようとすれば、超硬
としての十分な硬度が得られず、また色調も金色から白
色に移行した。本発明では、Ｎｊ，Ｃｒ，Ｆｅ以外にＮ
ｂＣと、ＴＩＣを含有させることにより、上記欠点を補
っている。Up until now, TIN-based cemented carbide had the effect of adding iron-based metals to improve its mechanical strength, but in order to have sufficient toughness, it was necessary to Sufficient hardness could not be obtained, and the color changed from gold to white. In the present invention, in addition to Nj, Cr, and Fe, N
By containing bC and TIC, the above drawbacks are compensated for.
つまり、Ｎ比は焼結性を改善し、機械的強度を向上させ
る一方、その含有量により、自由に金色色調を得ること
が出釆る。また、ＴＩＣは鉄系金属との需れが良く、そ
の含有により、焼結性を向上させ、靭性を得ることが出
来る。また、Ｎ比，ＴＩＣは結合金属と同様、多量に含
有した場合には、得られる超硬合金の色調は白色になる
ため、多く含有させる事は出来ない。In other words, while the N ratio improves sinterability and mechanical strength, depending on its content, it is possible to freely obtain a golden color tone. Further, TIC is in good demand with iron-based metals, and its inclusion can improve sinterability and obtain toughness. Further, like the bonding metal, if the N ratio and TIC are contained in a large amount, the color tone of the obtained cemented carbide becomes white, so it is not possible to contain a large amount.
逆に、少量の場合には、機械的強度の向上が期待出来な
くなる。従って、各元素の含有範囲は、いずれも重量比
にてＮｂＣ１５〜４５重量％、ＴＩＣ５．０〜５０％
Ｎｉ５〜３０％ Ｃｒ２〜１５％ Ｆｅｌ．５〜５％残
部ＴＩＮとするのが最も適当である。上記成分を有する
組成物は、ＨＩＰ処理による暁結成形された後、放電加
工により所定の形状に加工し、ダイヤモンド研磨により
鏡面加工を施す。Conversely, if the amount is small, no improvement in mechanical strength can be expected. Therefore, the content range of each element is 15 to 45% by weight of NbC and 5.0 to 50% of TIC.
Ni5-30% Cr2-15% Fel. It is most appropriate to set the balance TIN to 5 to 5%. The composition having the above-mentioned components is shaped by HIP processing, processed into a predetermined shape by electrical discharge machining, and mirror-finished by diamond polishing.
こうして得られた時計側は、美麗な金色を呈し、また、
抗折力が１４０〜１５０ｋ９／嫌と高く、耐衝撃性にす
