Description
本発明は、ナノサイズの窒化チタン粉末を対費用効果の高い方法で調製するための方法に関する。
窒化チタン(TiN)は、良好な耐摩耗性、良好な耐高温酸化性、高い高温強度及び高弾性率を有し、したがって、切削工具、防弾材料及び耐摩耗並びに耐熱性被覆の製造のために広範に使用される。窒化チタンの結晶サイズが細かくなればなるほど、焼結窒化チタン製品の硬度及び靭性はより良好となる。
したがって、ナノサイズの窒化チタン粉末の調製のための効率的で単純な方法を提供することが本発明の目的である。
本発明の方法は、(1)三塩化チタン(TiCl3)と窒化リチウム(Li3N)の混合粉末を、不活性ガス雰囲気下、気密反応容器中で複数のボールを使用する高エネルギーボールミル粉砕にかけ、複合粉末を生成すること、(2)複合粉末から、所望の窒化チタン(TiN)粉末を回収することを含む。窒化チタン粉末を調製するための本発明のプロセスの模式図は、図1に示される。
三塩化チタン(TiCl3)と窒化リチウム(Li3N)粉末が、1:1のモル比で混合され、3gの混合粉末を生成した。混合粉末は、125mlの工具鋼製の反応器中に置かれ、19個の直径9.5mmの超硬合金(WC-Co)ボールがそこに加えられた。使用されたボールの合計重量は90gであった。次いで、反応容器はアルゴンで満たされ、封止され、混合粉末は、4時間遊星ミルを使用して、高エネルギーボールミル粉砕を受け、複合粉末を生成した。ボールミル粉砕終了後、封止された反応器は、反応中に生成した気体状水素を放出するために開放され、次いで複合粉末が水に分散された。得られた分散物は、不溶物を分離するためにろ紙を使用してろ過され、不溶物は100℃で2時間、オーブンで乾燥され、窒化チタン(TiN)粉末を得た。
