表面被覆切削工具及其制造方法
摘要：
该表面被覆切削工具包括基材以及形成于基材上的覆膜，其特征在于：所述覆膜至少包括一层TiB2层，并且对于所述TiB2层，取向指数TC(hkl)中TC(100)为最大值，或者(100)面的X射线衍射强度I(100)与(101)面的X射线衍射强度I(101)间的比值I(100)/I(101)为1.2以上。
摘要（英）：

This coated surface cutting tool comprises a base material and a coating formed on the base material and is characterized in that: the coating comprises at least one TiB2 layer; and for said TiB2 layer, TC (100) in the orientation index TC (hkl) is maximal or the ratio I (100)/I (101) of the X-ray diffraction intensity of the (100) surface, I (100), to the X-ray diffraction intensity of the (101) surface, I (101), is 1.2 or more.
