ことを特徴とする時計用硬質外装部品に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides exterior parts for watches that have been subjected to surface hardening heat treatment.
do. For more details, please see the exterior parts for watches that have been subjected to surface hardening heat treatment.The exterior parts for watches that have been subjected to surface hardening heat treatment! ! !
1/l Ti1J, TaN, ZrN,
The present invention relates to a hard exterior part for a watch, characterized in that a golden nitride layer of 11fN or the like is formed and a contact-resistant material is added.
ここで時計用外装部品としては胴、裏ぶた。ガラス縁、
バンド、リエーズ等である。Here, the exterior parts for watches are the body and case back. glass rim,

従来の時計ケースはステンレス鋼、黄銅、亜鉛合金など
低硬変材そのままかあるいはめっきを施しｔものが殆ど
でこのため長期間携帯した場合にはかな秒の傷が見られ
装飾品としての価値を半減している。また金色の色調を
有する時計は金めりｔＩか殆どで硬さはＨｖ １５０〜
２５０と低いため容易く傷がついてしまう。Conventional watch cases are mostly made of low-hardness materials such as stainless steel, brass, and zinc alloys, or are plated.As a result, if the watch case is carried for a long period of time, scratches can be seen, making it less valuable as a decorative item. It has been halved. Also, most watches with a golden tone are gold-plated tI and have a hardness of Hv 150~
Since it is low at 250, it gets scratched easily.
このため傷かつ＃ソくいということで超硬合金。For this reason, it is made of cemented carbide because it is scratched and soft.
ステライト。ニッケル基硬質合金などが市場に出ている
。しかしこうしたケースは携帯中に誤って落した場合に
割れ中すがったり、加工性が悪く製造コストを高くする
欠点をホしている。Stellite. Nickel-based hard alloys are on the market. However, these cases have drawbacks such as cracking if accidentally dropped while carrying the phone, and poor workability, which increases manufacturing costs.

のである。The present invention eliminates such drawbacks by performing normal forging, cutting, and grinding! subjected to ratio treatment or boriding treatment.
TiN Misaki Oi also lightly polished l1III! The purpose is to form a high-quality coating to provide exterior parts that are corrosion resistant and wear resistant, and are resistant to cracking and scratches even when swallowed.
超硬合金は硬さＨｖ １０００を超重るため接材加工が
不可で放電加工によっており、一方ステライト。Cemented carbide has a hardness of over 1000 Hv, so it cannot be processed by welding, so it is processed by electrical discharge machining, while Stellite.
ニッケル基合金は硬さＨｖ １０００以下のため傷がつ

耐蝕性の改善、、：ＴｉＨの持つ高硬さＨｖ ２４００
を利用して下゛地硬さとあいまって傷がつきにくい特做
を発揮させたものである。Nickel-based alloys have a hardness of Hv 1000 or less, so they have the disadvantage of being scratched.
When stainless steel is nitrided, the hardness is 0.
1 m, hardness Hv 1400, and its superiority is unparalleled. However, if left as is, the corrosion resistance deteriorates and is not practical, so a hard coating such as TiH is formed to improve the corrosion resistance.
The use of this material, combined with the hardness of the base, makes it scratch resistant.
硬質被膜を得る方法としてはＰＶＤ法、ｃｖ′Ｄ法があ
るが処理温度、密層性、被覆性岬を考えればＰＶＤ法が
優れておシ轡にイオンプレーティング法が近年注目され
多用されている。There are PVD and CV'D methods to obtain hard coatings, but the PVD method is superior in terms of processing temperature, layer density, and coverage, and the ion plating method has attracted attention and is widely used in recent years. There is.

宏で良ることは言うまでもない。In the present invention B) 4, reactive ion blating method was used or OVD method was used to coat the 9ide.
Needless to say, Hiroshi is a good thing.
以下に″＃施例によ１１する。The following is an example 11.
〔実施例１〕
１８−８ステンレス鋼製の仕上ね胴をイオン♀化法によ

４０Ｑとした上で表面の光沢出しのため）ぐ７研磨した
。[Example 1] A finished drum made of 18-8 stainless steel was nitrided using the ionization method, and the total hardening depth was 01.
After polishing to 40Q, polishing was performed for 7 times to make the surface glossy.
この窒化処理を施した加ＩＫイオンブレーティング法を
用いて窒化チタン膜を１０μｍ被覆した。A titanium nitride film having a thickness of 10 μm was coated using the IK ion blating method using this nitriding treatment.
部品を人工汗浸漬試験（５５℃、９６Ｈ）、環水噴霧試
験（３５℃、９６Ｈ）ｔζ供した結果腐蝕点の発生は何
ら認められなかった。The parts were subjected to an artificial sweat immersion test (55°C, 96H) and a water spray test (35°C, 96H), and no corrosion points were observed.
〔実施例２〕
１８−８ステンレスｆＩ１４製の仕上り胴を固体硼化法
により硼化処理し全硬化深さ０２龍、表面硬さＨｖ ２
４００とした上でｉ面の光沢出しのためバク研磨した。[Example 2] A finished cylinder made of 18-8 stainless steel fI14 was borated using a solid boriding method to achieve a total hardening depth of 02 and a surface hardness of Hv2.
400 and then back-polished to make the i-side glossy.
この硼化処理を施した胴に実施例１と同−Ｃ＋方法で９
化チタン膜を形成し同一の方法で耐蝕性試験を行った。9. The same -C+ method as in Example 1 was applied to the boronized body.
A titanium oxide film was formed and a corrosion resistance test was conducted using the same method.
その結果腐蝕点の発生は伺ら認められなかった。As a result, no corrosion spots were observed.
以上述べた通す下地表面を窒化法、硼化法等で硬化した
