Description
耐摩滅性潤滑特性を決定する重要な要因は、合金の組成及び内部組織であり、これまで合金の組成の改善に研究の焦点が合わせられてきた。
本発明の合金と対照群の合金に対して摩耗率、耐蝕性及び硬度を含む物理化学的特性を次のような方法で測定した。
接動する試料の表面摩耗状態を観察するためにASTM G−99に基づいて摩擦実験を実施した。直径2mmのピン(pin)で加工した合金試料を100rpmで回転する金属円板(disk)(ステインレス鋼316)に対して20kgの荷重で60分間摩擦させた後、試料の摩擦面を観察した。
本発明の合金を産業機械だけでなく、化学機械及び食品加工機械にも用いるためには耐酸性を持たなければならない。耐酸性を試すために、各合金試料を50℃で維持された濃硫酸、濃塩酸及び濃窒酸にそれぞれ360時間浸漬して腐蝕速度を測定した。その結果は次の表3に示す。硫酸溶液では本発明合金と対照群合金がほぼ同一な腐蝕速度を示している。しかし、塩酸及び窒酸溶液では対照群合金に比べて本発明の合金の腐蝕速度が顕著に低く、耐酸性も優れていることが分かる。
本発明の合金はローター、シャフトなどのような構造的湿動部品として用いられるため、相当な硬度を持たなければならない。従って、標準化した試験法によりビッカース(Vickers)硬度を測定した。下記表4でのように、本発明の合金が対照群の合金に比べて同等ないし優秀な硬度を示している。これは微細な析出相の均一分布だけでなく、微細構造によるピニング效果(pinning effect)によるものと解釈される。
Claims (4)
- Ni70〜75質量%、Cr8〜14質量%、Bi3〜7質量%、Sn3〜6質量%、Mo1〜4質量%、(Fe+Si)2質量%以下、Te1〜3質量%及び不可避不純物からなる耐摩滅性潤滑合金。
- 前記合金の基質(matrix)が緻密な樹枝状組織(dendritic structure)からなり、前記樹枝状組織の間隙に微細なBi−リッチ析出相が均一に分散していることを特徴とする請求項1に記載の耐摩滅性潤滑合金。
- 他金属と接触したときに前記Bi−リッチ析出相が合金表面を覆って摩擦係数及び摩耗率を低減させ、摩擦表面での応力によるクラッキングを防止することを特徴とする請求項2に記載の耐摩滅性潤滑合金。
- 機械装置の部品として用いることを特徴とする請求項1に記載の耐摩滅性潤滑合金。
