Description
−1,0)面の結晶方位に配向していることを特徴とする。
,0,1)面の結晶方位を示す色を呈している結晶の面積を粗粒子21の総面積で割り、
(0,0,0,1)面に配向している粒子の割合を算出する。同様に微粒子22の(1,0,−1,0)面に配向する色を呈している結晶の割合、中粒子23の(0,1,−1,0)面の結晶方位への配向を示す色を呈している結晶の割合を算出する。
(製造方法)
ここで、本発明の切削工具を作製する方法の一例について説明する。
まず、反応ガス組成として四塩化チタン(TiCl4)ガスを0.5〜10体積%、窒素(N2)ガスを10〜60体積%、残りが水素(H2)ガスからなる混合ガスを調整して反応チャンバ内に導入し、チャンバ内を800〜940℃、8〜50kPaの条件で下地層であるTiN層3を成膜する。
、これらの測定値の平均値を各結晶の測定値とした。結果は表3に示した。
被削材 :ダクタイル鋳鉄8本溝入りスリーブ材(FCD700)
工具形状:CNMA120412
切削速度:300m/分
送り速度:0.3mm/rev
切り込み:1.0mm
その他 :水溶性切削液使用
評価項目: 摩耗量が0.3mmとなった時の切削時間を測定した。また、切削直後、切削時間3分経過した後の切刃の状態をそれぞれ観察した。結果は表4に示した。
