Description
発明品及び比較品の被覆切削工具の製造に使用したアークイオンプレーティング装置の反応容器内で、金属蒸発源に対向する側の被覆切削工具試料の断面をダイヤモンドペーストで鏡面研磨した。得られた試料の断面から、被覆層の各層の組成を株式会社日立ハイテクノロジーズ製走査電子顕微鏡S−6600および透過電子顕微鏡付属のEDSを用いて測定した。
試料における被覆層の各層の平均層厚(上層が多層構造体の場合は、それを構成する各層の平均層厚)については、光学顕微鏡、走査電子顕微鏡S−6600および透過電子顕微鏡を用い、金属蒸発源に対向する側の試料の断面をダイヤモンドペーストで鏡面研磨し、得られた試料の断面を5箇所測定し、その平均値を求めた。
発明品及び比較品の被覆切削工具試料の最下層構成粒子の平均粒径は以下のように測定した。最下層の表面に形成された上層をイオンミリングによって除去した。上層を除去して現れた最下層の表面を、株式会社TSLソリューションズ製EBSD装置を用い、ステップサイズを0.01μm、測定範囲を2μm×2μmに設定し、方位差が5°以上の境界を粒界とする最下層の表面組織の画像から、最下層構成粒子の平均粒径を求めた。
基材として、K20相当のISO規格SEEN1204インサート形状の超硬合金を用意した。
得られた発明品及び比較品の被覆切削工具試料を下記のカッターに取り付けて、下記の条件で切削試験を行った。
被削材:FCD600、
切削速度:150m/min、
送り:0.2mm/tooth、
切り込み:2.0mm
切削幅:46mm、
クーラント:不使用(ドライ加工)
加工距離:(1)0.8m、(2)2.0m、(3)工具寿命に至るまでの加工距離、
工具寿命の判定:最大逃げ面摩耗幅が0.2mmに至ったときを工具寿命とする、
カッター:有効径80mmのカッター。
