Description
400MPa≦|S1−S2|≦3500MPa・・・(I)
0≦|SS1−SS2|≦500MPa・・・(II)
本発明の表面被覆切削工具は、基材と、該基材上に形成された被膜とを備える構成を有している。
上記基材としては、このような切削工具の基材として知られる従来公知のものを特に限定なく使用することができる。たとえば、このような基材として、超硬合金(たとえばWC基超硬合金、WCの他、Coを含み、あるいはさらにTi、Ta、Nb等の炭窒化物を添加したものも含む)、サーメット(TiC、TiN、TiCN等を主成分とするもの)、高速度鋼、セラミックス(炭化チタン、炭化硅素、窒化硅素、窒化アルミニウム、酸化アルミニウムなど)、立方晶型窒化硼素焼結体、ダイヤモンド焼結体、窒化硅素焼結体、または酸化アルミニウムと炭化チタンとからなる混合体等を挙げることができる。
図6に示したように上記基材8上に形成される被膜9は、主として更なる靭性の向上と更なる耐摩耗性の向上とを目的として形成されるものであり、TiCNからなる第1被膜10と、α型Al2O3からなる第2被膜11とを含むものである。
本発明の第2被膜は、α型Al2O3からなるものである。このような素材で構成される第2被膜を、基材の最表面または最表面近傍に形成することにより、基材の酸化を効果的に防止するとともに切削加工時において被削材の構成元素が基材側に拡散することを極めて有効に防止することができる。
400MPa≦|S1−S2|≦3500MPa・・・(I)
本発明の第1被膜は、上記基材と上記第2被膜との間に位置し、TiCNからなるものである。上記α型Al2O3からなる第2被膜は、上記のような優れた効果を有するものであるが、相対的に脆いという特性を有しており、このため耐アブレッシブ摩耗性が特に重視される切削温度が比較的低い用途においてより高度な耐摩耗性が求められることがある。本発明の第1被膜は、正しくこのような要求を満たすことを目的として形成されるものであり、それ自身高温での切削で酸化され易いという特性があるものの非常に高い硬度を有することから、上記第2被膜と基材との間に位置することにより、耐摩耗性を飛躍的に向上させる作用を奏するものである。
0≦|SS1−SS2|≦500MPa・・・(II)
以下、実施例を挙げて本発明をより詳細に説明するが、本発明はこれらに限定されるものではない。
WC:86質量%、Co:8.0質量%、TiC:2.0質量%、NbC:2.0質量%、ZrC:2.0質量%の配合割合で各原材料粉末をボールミルを用いて72時間湿式混合した。続いて、その混合物を乾燥した後プレス成形した。そしてその後、真空雰囲気中で1420℃、1時間の条件で焼結を行なった。
被削材:SCM435溝付き丸棒、
切削速度:230m/min
送り:0.15mm/rev.
切込み:0.5mm
切削油:無し
上記実施例1〜5において、上記領域A1を刃先稜線部からすくい面の方向と逃げ面の方向とにそれぞれ1.5mmの距離をもって広がった領域とすることを除き、他は全て同様にして実施例6〜10の表面被覆切削工具を得た(実施例1〜5と実施例6〜10の対応関係はそれぞれ番号順に対応するものとし、表1に示したのと同様の応力分布を示すように調整した)。
