    • Provided is a coated tool exhibiting enhanced wear resistance and adhesiveness of an aluminum oxide layer and superior wear resistance and defect resistance. A cutting tool (1) in which at least a titanium carbonitride layer (8) and an aluminum oxide layer (10) having an α-type crystalline structure are laminated in that order on a surface of a substrate (5). A surface-side Tc(116) in a surface-side peak is greater than a substrate-side Tc(116) in a substrate-side peak where Tc(116) is an orientation factor of the aluminum oxide layer (10) when comparing the substrate-side peak detected by measuring a portion on a substrate (5) side of the aluminum oxide layer (10) and the surface-side peak detected by measuring a portion on a surface side of the aluminum oxide layer (10) in X-ray diffraction analysis of the aluminum oxide layer (10).
    • 本发明提供一种涂层工具,其表现出增强的氧化铝层的耐磨性和粘附性以及优异的耐磨性和耐缺陷性。 一种切削工具,其特征在于,在基材的表面上至少依次层叠碳氮化钛层和具有α型结晶结构的氧化铝层而成的切削工具。 当比较时,Tc(116)是氧化铝层(10)的取向因子的表面侧峰值中的表面侧Tc(116)大于衬底侧峰值中的衬底侧Tc(116) 通过测量氧化铝层(10)的衬底(5)侧上的部分和通过测量X中的氧化铝层(10)的表面侧上的部分而检测到的表面侧峰来检测衬底侧峰值 - 氧化铝层(10)的X-射线衍射分析。
