具体实施方式
＜涂层刀具＞
以下，使用附图详细说明本公开的各种实施方式的涂层刀具。其中，以下参照的各图为了说明的方便而仅简略地示出对于说明实施方式而言必需的主要构件。因此，本公开的涂层刀具可以具备用于参照的各图中未示出的任意构成构件。另外，各图中的构件的尺寸并未忠实地表示实际的构成构件的尺寸和各构件的尺寸比率等。这一点在后述的切削刀具中也是同样的。
实施方式的一例的涂层刀具1为四角板形状，具有四边形的第一面3(图1中的上表面)、第二面5(图1中的侧面)、和位于第一面3与第二面5相交的脊线的至少一部分处的切削刃7。另外，一例的涂层刀具1还具有四边形的第三面8(图1中的下表面)。
一例的涂层刀具1中，第一面3的整个外周可以成为切削刃7，但是涂层刀具1不限于这种构成，可以是例如，四边形的第一面3中的仅一条边或局部地具有切削刃7。
第一面3可以在至少一部分具有前刀面区域3a。在实施方式的一例中，第一面3中的沿着切削刃7的区域成为前刀面区域3a。第二面5可以在至少一部分具有后面区域5a。在实施方式的一例中，第二面5中的沿着切削刃7的区域成为后面区域5a。因此，也可以说切削刃7位于前刀面区域3a与后面区域5a相交的部分。
图1中，用单点划线示出第一面3中的前刀面区域3a与其以外的区域的边界。另外，用单点划线示出第二面5中的后面区域5a与其以外的区域的边界。图1中示出了第一面3与第二面5相交的脊线全部为切削刃7的例子，因此，在第一面3中，表示上述边界的单点划线成为环状。
涂层刀具1的大小没有特别限定，例如，在实施方式的一例中，第一面3的一条边的长度可设定为3～20mm左右。另外，第一面3至位于第一面3的相反侧的第三面8为止的高度可设定为5～20mm左右。
如图1和图2所示，一例的涂层刀具1具备四角板形状的基体9、和被覆该基体9表面的涂层11。涂层11可以覆盖基体9的整个表面，另外，也可以仅被覆一部分。在涂层11仅被覆基体9的一部分时，也可以说涂层11位于基体9上的至少一部分。
作为涂层11的厚度，例如可设定为0.1～10μm左右。需要说明的是，涂层11的厚度可以固定，也可以根据部位而不同。
如图3和图4所示，涂层11具有多个含有铝(Al)和钛(Ti)作为主要成分的AlTi层13、以及多个含有铝和铬(Cr)作为主要成分的AlCr层15。涂层11为多个AlTi层13和多个AlCr层15的位置交替的构成。换言之，涂层11为多个AlTi层13和多个AlCr层15交替层叠的构成。涂层11的层叠结构能够通过使用扫描型电子显微镜(SEM：Scanning ElectronMicroscopy)或透射型电子显微镜(TEM：Transmission Electron Microscopy)等的剖面测定来评价。
AlTi层13中，除了含有铝和钛以外，还含有铬。另外，AlTi层13可以含有Si、Nb、Hf、V、Ta、Mo、Zr和W等金属成分。但是，在AlTi层13中，与铬和上述的金属成分相比，铝和钛各自的含有比率的合计较高。铝的含有比率可设定为例如40～70％。另外，钛的含有比率可设定为例如25～55％。需要说明的是，上述中的“含有比率”表示以原子比计的含有比率。
可以是在多个AlTi层13的每一层中铝的含有比率高于钛的含有比率，另外，也可以是在多个AlTi层13的每一层中钛的含有比率高于铝的含有比率。另外，多个AlTi层13均以比铝和钛各自的含有比率的合计少的比率含有铬，铬的含有比率可设定为例如0.1～20％。
AlTi层13可以仅由包含铝、钛和铬的金属成分构成，铝、钛和铬也可以是包含它们中的单独一种或多种的氮化物、碳化物或碳氮化物。
AlCr层15可以仅由铝和铬构成，也可以除了含有铝和铬以外还含有Si、Nb、Hf、V、Ta、Mo、Zr、Ti和W等金属成分。但是，在AlCr层15中，与上述的金属成分相比，铝和铬各自的含有比率的合计高。铝的含有比率可以设定为例如20～60％。另外，铬的含有比率可以设定为例如40～80％。
可以是在多个AlCr层15的每一层中铝的含有比率高于铬的含有比率，另外，也可以是在多个AlCr层15的每一层中铬的含有比率高于铝的含有比率。
另外，AlCr层15可以仅由包含铝和铬的金属成分构成，铝和铬也可以是包含它们中的单独一种或两种的氮化物、碳化物或碳氮化物。
AlTi层13和AlCr层15的组成例如能够通过能量色散型X射线光谱分析法(EDS)或X射线光电子能谱分析法(XPS)等进行测定。
AlTi层13和AlCr层15的数量不限于特定的值。AlTi层13和AlCr层15的数量只要分别为2层以上即可，可设定为例如2～500。
涂层11由于具有AlTi层13而耐缺损性高。另外，涂层11具有AlCr层15，因此耐摩耗性高。涂层11为多个AlTi层13和多个AlCr层15的位置交替的构成，因此涂层11的整体强度高。
需要说明的是，与多个AlTi层13和多个AlCr层15各自的厚度厚、且多个AlTi层13和多个AlCr层15的数量少的情况相比，多个AlTi层13和多个AlCr层15各自的厚度薄、且多个AlTi层13和多个AlCr层15的数量多的情况下，涂层11的整体强度高。
AlTi层13和AlCr层15的厚度不限于特定的值，例如，可以分别设定为5nm～100nm。需要说明的是，多个AlTi层13和多个AlCr层15的厚度可以固定，也可以彼此不同。
如图4所示，实施方式的一例中的多个AlTi层13具有第1AlTi层13a和第2AlTi层13b。第2AlTi层13b与第1AlTi层13a相比位置更远离基体9。涂层刀具1为第2AlTi层13b中的铬的含有比率高于第1AlTi层13a中的铬的含有比率的构成。满足这些构成的涂层刀具1的耐久性优异。
如AlTi层和AlCr层这样，组成不同的层的位置交替的情况下，有在相邻的层间的界面处发生剥离的担忧。特别是在切削加工时容易对涂层刀具的外表面施加负荷，因此上述的界面中的靠近涂层刀具的外表面的部分处容易发生上述剥离。
在实施方式的一例中，如前所述，AlTi层13含有铝和钛作为主要成分，以比铝和钛各自的含有比率的合计少的比率含有铬。满足这种构成的AlTi层13由于相对地维持了AlTi层13的特性、并且与AlCr层15同样地含有铬，因此与AlCr层15的亲和性高。因此，AlTi层13与相邻的AlCr层15的接合性(密合性)高。
在切削加工时，与第1AlTi层13a相比位置更远离基体9的第2AlTi层13b容易被施加大于第1AlTi层13a的切削负荷。就实施方式的一例的涂层11而言，由于第2AlTi层13b中的铬的含有比率高于第1AlTi层13a中的铬的含有比率，因此与相邻的AlCr层15的接合性高，可耐受大的切削负荷。
另外，第1AlTi层13a中的铬的含有比率低于第2AlTi层13b中的铬的含有比率。由此，不易在涂层11中的靠近基体9的部分处发生剥离，并且，可以在涂层11的整体上减小对AlTi层13的耐缺损性的影响。
因此，一例的涂层刀具1不易发生层间剥离，耐久性优异。因此，根据一例的涂层刀具1，可以长期进行稳定的切削加工。
多个AlTi层13可以还具有第3AlTi层13c，其位于第1AlTi层13a与第2AlTi层13b之间。涂层刀具1可以为下述构成：第3AlTi层13c中的铬的含有比率高于第1AlTi层13a中的铬的含有比率、且低于第2AlTi层13b中的铬的含有比率。满足这种构成的涂层刀具1的耐久性优异。
这是由于，在包含第1AlTi层13a、第2AlTi层13b和第3AlTi层13c的多个AlTi层13中，铬的含有比率阶梯性缓慢变化，避免了急剧变化。由此，避免了韧性和硬度在多个AlTi层13中急剧变化，容易避免由在涂层11的内部发生应力集中而引起的裂纹产生等。
需要说明的是，图4中，涂层11具有5个以上的AlTi层13，另外，AlCr层15分别位于第1AlTi层13a与第3AlTi层13c之间、以及第3AlTi层13c与第2AlTi层13b之间。
多个AlTi层13中，可以是位置越远离基体9则铬的含有比率越高。换言之，在涂层11具有4个以上的AlTi层13时，多个AlTi层13中，位置越远离基体9则铬的含有比率越高。在满足这种构成时，可以更进一步提高涂层刀具1的耐久性。这是由于，避免了韧性和硬度在多个AlTi层13中急剧变化、并且容易使多个AlTi层13中的最远离基体9的AlTi层13中的铬的含有比率非常高。
第2AlTi层13b中的铝的含有比率可以低于第1AlTi层13a中的铝的含有比率。在满足这种构成时，与第2AlTi层13b相比，第1AlTi层13a的韧性高。因此，涂层11的密合性优异。
如图5所示，在多个AlTi层13中，位于AlCr层15之间的AlTi层13d可以具有：包含位于基体9侧的内侧面131的第1区域13d1；包含位于内侧面131的相反侧的外侧面132的第2区域13d2；和位于第1区域13d1与第2区域13d2之间且包含厚度方向a的中央133的第3区域13d3。
此时，第1区域13d1和第2区域13d2中的铬的含有比率可以高于第3区域13d3中的铬的含有比率。在满足这些构成时，面对AlCr层15的第1区域13d1和第2区域13d2中的铬的含有比率相对高，因此AlTi层13与AlCr层15的接合性进一步提高。
如后所述，基体9可以含有碳化钨(WC)和钴(Co)。此时，多个AlTi层13中，至少位置最靠近基体9的AlTi层13e可以含有钴、且钴的含有比率高于铬的含有比率。位置最靠近基体9的AlTi层13e含有钴的情况下，涂层11对基体9的接合性高。
此外，当钴的含有比率高于铬的含有比率时，因钴的含有比率相对高而涂层11相对于基体9的接合性高，因铬的含有比率被抑制而上述的AlTi层13e的韧性高。
需要说明的是，如图1所示，一例的涂层刀具1为四角板形状，但是涂层刀具1的形状不限于这种形状。例如，第一面3和第三面8不是四边形而是三角形、六边形或圆形等也没有任何问题。
如图1所示，一例的涂层刀具1具有贯通孔17。实施方式的一例中的贯通孔17从第一面3形成至位于第一面3的相反侧的第三面8，并开口于这些面。贯通孔17能够在将涂层刀具1保持于刀杆时用于安装螺钉或固定构件等。需要说明的是，贯通孔17即使是在第二面5中的彼此位于相反侧的区域中进行开口的构成也没有任何问题。
作为基体9的材质，可列举例如超硬合金、金属陶瓷和陶瓷等无机材料。作为超硬合金的组成，可列举例如WC(碳化钨)－Co、WC－TiC(碳化钛)－Co和WC－TiC－TaC(碳化钽)－Co等。在此，WC、TiC和TaC为硬质粒子，Co为结合相。另外，金属陶瓷是使陶瓷成分中复合有金属的烧结复合材料。具体而言，作为金属陶瓷，可列举以TiC或TiN(氮化钛)作为主要成分的化合物等。需要说明的是，作为基体9的材质，不限定于这些。
涂层11例如能够通过使用物理蒸镀(PVD)法等而使其位于基体9上。例如，在于贯通孔17的内周面保持基体9的状态下利用上述蒸镀法形成涂层11的情况下，能够使涂层11以被覆除了贯通孔17内周面之外的基体9的整个表面的方式位于基体9上。
作为物理蒸镀法，可列举例如离子镀法和溅射法等。作为一例，在利用离子镀法制作的情况下，可以通过下述方法来制作涂层11。
作为第一步骤，准备分别独立地含有铝、钛及铬的金属靶、复合化的合金靶或烧结体靶。通过电弧放电或辉光放电等使作为金属源的上述靶蒸发而离子化。使离子化了的靶与作为氮源的氮(N2)气、作为碳源的甲烷(CH4)气或乙炔(C2H2)气等反应，并且使其蒸镀于基体9的表面。通过以上的步骤可形成AlTi层13。
作为第二步骤，准备分别独立地含有铝及铬的金属靶、复合化的合金靶或烧结体靶。利用电弧放电或辉光放电等使作为金属源的上述靶蒸发而离子化。使离子化了的靶与作为氮源的氮(N2)气、作为碳源的甲烷(CH4)气或乙炔(C2H2)气等反应，并且使其蒸镀于基体9的表面。通过以上的步骤，可形成AlCr层15。
通过交替重复进行上述第一步骤和第二步骤，可形成多个AlTi层13与多个AlCr层15交替层叠的构成的涂层11。需要说明的是，先进行第二步骤、然后进行第一步骤也没有任何问题。
在此，在重复进行第一步骤时，通过在过程中按照铬的比率提高的方式改变铬的比率，从而能够制作具有第1AlTi层13a和第2AlTi层13b的多个AlTi层13。
例如，在重复进行第一步骤时，通过从最初进行第一步骤起直至最后一次进行第一步骤时，按照铬的比率逐渐提高的方式改变铬的比率，从而能够使位置越远离基体9的AlTi层13的铬的含有比率越高。
＜切削刀具＞
然后，使用附图说明本公开的各实施方式的切削刀具。
如图6所示，实施方式的一例的切削刀具101为从第1端(图6中的上端)向着第2端(图6中的下端)延伸的棒状体。如图7所示，切削刀具101具备：在第1端侧(前端侧)具有凹处103的刀杆105；和位于凹处103的上述的涂层刀具1。切削刀具101具备涂层刀具1，因此可以长期进行稳定的切削加工。
凹处103是安装涂层刀具1的部分，具有相对于刀杆105的下表面平行的坐落面、和相对于坐落面倾斜的约束侧面。另外，凹处103在刀杆105的第一端侧开口。
涂层刀具1位于凹处103。此时，涂层刀具1的下表面可以与凹处103直接接触，另外，也可以在涂层刀具1与凹处103之间夹有垫片(未图示)。
涂层刀具1按照第一面3与第二面5相交的脊线中的作为切削刃7而使用的部分中的至少一部分从刀杆105向外侧突出的方式安装于刀杆105。实施方式的一例中，涂层刀具1通过固定螺钉107安装于刀杆105。即，向涂层刀具1的贯通孔17中插入固定螺钉107，将该固定螺钉107的前端插入至形成于凹处103的螺钉孔(未图示)并将螺钉部彼此螺合，由此涂层刀具1被安装于刀杆105。
作为刀杆105的材质，可使用钢、铸铁等。在这些构件中，可以使用韧性高的钢。
实施方式的一例中，例示了在所谓的车削加工中使用的切削刀具。作为车削加工，可列举例如内径加工、外径加工和开槽加工等。需要说明的是，作为切削刀具，不限于车削加工中使用的刀具。例如，也可以将上述实施方式的涂层刀具1用于铣削加工所使用的切削刀具。
另外，在本公开的整体中，关于单数形式“一”、“上述”和“所述”，如果从上下文不能明确为单数，则也包括多个。
