【発明の詳細な説明】
（Ａ）産業上の利用分野
本発明は、歯車（以降ギアともいう）に関し、特に腐蝕
性、耐久性に優れた歯車に関する。DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to a gear (hereinafter also referred to as a gear), and particularly to a gear with excellent corrosion resistance and durability.
（Ｂ）従来技術及びその問題点
歯車は種々の機械に動力の伝達手段として広く用いられ
ているが、動力の伝達手段のみにとどまらず、液体の定
量ポンプ（以降ギアポンプともいう）の定量手段として
使用されている。(B) Prior art and its problems Gears are widely used as a power transmission means in various machines, but they are not only used as a power transmission means, but also as a metering means for liquid metering pumps (hereinafter also referred to as gear pumps). It is used.
歯車の材質は金属であることから一般的に水系の流体に
接触すると腐蝕しやすい性質を有しているので、腐蝕し
にくいステンレスが、その材質として一般に使用されて
いる。Since gears are made of metal, they generally tend to corrode when they come into contact with water-based fluids, so stainless steel, which is resistant to corrosion, is generally used as the material.
しかしながら、ステンレスを材質として用いた歯車であ
っても、酸性あるいはアルカリ性の水溶液との接触によ
って、その耐腐蝕性並びに耐摩耗性が著しく損われると
いう問題がある。この腐蝕及び摩耗はポンプの定量精度
を損うとともに、被定量液の化学的、物理的液性に悪影
響を与えることとなり好ましくない。However, even gears made of stainless steel have a problem in that their corrosion resistance and wear resistance are significantly impaired by contact with acidic or alkaline aqueous solutions. This corrosion and abrasion impair the metering accuracy of the pump and adversely affect the chemical and physical properties of the liquid to be metered, which is undesirable.
（Ｃ）発明の目的
本発明の目的は、耐腐蝕性並びに耐摩耗性に優れた歯車
を提供するにある。(C) Purpose of the Invention The purpose of the present invention is to provide a gear with excellent corrosion resistance and wear resistance.
本発明の他の目的は耐腐蝕性並びに耐摩耗性に優れたギ
アポンプ用の歯車を提供するにある。Another object of the present invention is to provide a gear for a gear pump that has excellent corrosion resistance and wear resistance.
本発明の他の目的は酸性あるいはアルカリ性水溶液の送
液に用いられるギアポンプに適した耐腐蝕性並びに耐摩
耗性に優れた歯車を提供するにある。Another object of the present invention is to provide a gear having excellent corrosion resistance and wear resistance and suitable for a gear pump used for pumping acidic or alkaline aqueous solutions.
（Ｄ）発明の構成
本発明の目的は少なくとも表面がセラミックで構成され
た歯車とし、これを用いることにより達成することがで
きた。(D) Structure of the Invention The object of the present invention was achieved by using a gear whose at least the surface is made of ceramic.
本発明の歯車は歯車全体がセラミックで構成されていて
もよいし、歯車の表面のみがセラミックで構成されてい
てもよい。In the gear of the present invention, the entire gear may be made of ceramic, or only the surface of the gear may be made of ceramic.
本発明に用いられるセラミックとしては、アルミナ、窒
化ケイ素、窒化チタン、ジルコニア、炭化ケイ素等が挙
げるが、中でも所謂エンジニアリングセラミックス・ニ
ューセラミックスと呼ばれるものが、耐腐蝕性、耐摩耗
性に優れており、好ましく用いられる。Ceramics used in the present invention include alumina, silicon nitride, titanium nitride, zirconia, silicon carbide, etc. Among them, so-called engineering ceramics and new ceramics have excellent corrosion resistance and wear resistance. Preferably used.
本発明の歯車の製法としては、歯車全体をセラミックで
構成する場合には成型方法が用いられる。As a manufacturing method for the gear of the present invention, a molding method is used when the entire gear is made of ceramic.
一方、表面のみをセラミックで構成する場合には、金属
等で成型された歯車の表面を溶射法、蒸着法、無電解メ
ツキ法等で処理することにより得ることができるが、特
に無電解メツキ法は被表面処理基体の形状にかわらず、
均一な薄膜（２０〜４０μ）が得られるので好ましい。On the other hand, when only the surface is made of ceramic, it can be obtained by treating the surface of a gear molded with metal etc. by a thermal spraying method, a vapor deposition method, an electroless plating method, etc. Regardless of the shape of the substrate to be surface treated,
This is preferred because a uniform thin film (20 to 40μ) can be obtained.
例えば複合無電解ニッケルメッキ（組成Ｎ１−Ｐ−８ｉ
ｃ）が好ましく用いられる。For example, composite electroless nickel plating (composition N1-P-8i
c) is preferably used.
（Ｅ）実施例 次に本発明の実施例を示すが、これに限定されない。(E) Examples Next, examples of the present invention will be shown, but the present invention is not limited thereto.
