Description
本発明の目的は、熱処理(SMC)部品、特に、理論密度の約89%超の密度(鉄系粉末から製造される部品では、約7.0g/cm3超)を有し、酸化性雰囲気下で通常の熱処理をすることによってより高い機械強度が実現されたSMC圧密体と比較してより低い保磁力を有する部品の機械強度を増進するための方法を提供することである。
本発明の上記の目的は、潤滑剤を含む粉末組成物を圧密して圧密体にするステップと、圧密体を潤滑剤の蒸発温度より高い温度まで加熱して、圧密体から潤滑剤を実質的に除去するステップと、得られた熱処理圧密体を、ナノメートルサイズ及び/又はマイクロメートルサイズの補強構造体を含む液状ポリマー複合材料にさらすステップと、乾燥及び/又は少なくとも1つの硬化処理によって、液状ポリマー複合材料を含む熱処理圧密体を固化させるステップとを含む、複合部品を製造するための方法によって達成される。
公知の含浸又は浸透方法と異なり、本発明は、鉄系粉末から製造された圧密体のような7.70g/cm3もの高密度の物体にポリマー複合液体が十分浸入することを可能とするものである。従って、本発明による含浸SMC圧密体は、低温から高温(例えば、約150℃超)までの広い範囲において予期し得ないほど高い機械強度、改良された機械加工特性、及び改良された耐腐食性を発揮することができる。
出発材料として、Hoganas ABから入手可能なSomaloy(登録商標)700を使用した。1つの組成物(試料A)を0.3重量%の有機潤滑剤であるステアルアミドと混合し、第2の組成物(試料B)を0.6重量%の有機潤滑結合剤であるポリアミドOrgasol(登録商標)3501と混合した。

表2
*エチレンビスステアルアミド(Acrawax(登録商標))
この例では、Somaloy(登録商標)700の平均粒径より小さい平均粒径を有するHoganasから入手可能なSomaloy(登録商標)500粉末を使用した。Somaloy(登録商標)500を0.5重量%のステアルアミドと混合し、80℃のツール金型温度を使用して800MPaで圧密した。2つの圧密試料は500℃において不活性ガス中で15分間さらに熱処理した(試料F及びG)。試料Gは、CNTで補強した嫌気性アクリル樹脂を使用して本発明による含浸に更に供した。
出発材料として、Hoganas ABから入手可能なSomaloy(登録商標)700を使用した。粉末試料はすべて、0.3重量%の有機潤滑剤であるステアルアミドと混合した。組成物を1100MPaで圧密し、密度7.58g/cm3のTRSバー(30×12×6mm)とした。金型温度を温度80℃に制御した。機械特性を例1に従って測定し、以下の表4にまとめた。
表4
出発材料として、Hoganas ABから入手可能なSomaloy(登録商標)700を使用した。粉末試料すべてを0.3重量%の有機潤滑剤であるステアリルエルカミド(SE)と混合した。試料3を、0.2重量%のSEを使用して7.63g/cm3まで圧密した以外は、組成物を金型温度60℃を使用して、800MPa又は1100MPaで圧密し、密度7.54g/cm3まで圧密した。
