    • The present invention provides a composite material that is excellent in the bonding ability between a cemented carbide layer and a cermet layer is excellent and deformation after sintering can be suppressed and a coated cutting tool having a base containing the composite material. A composite material 10ii is obtained by laminating a cemented carbide layer 11 and a cermet layer 12 and has the cemented carbide layer 11 on the surface side. The boundary between both the layers 11 and 12 has a concave portion 23, and the maximum depth Dmax of the concave portion 23 is 50 μm or more and 500 μm or lower. When the thickness of the composite material is defined as h1 and the thickness of the cemented carbide layer 11 is defined as h2, h2/h1 is in the range of more than 0.02 and 0.4 or lower. By providing the concave portion 23 to the boundary, both the layers 11 and 12 are sufficiently bound and the bonding ability therebetween is excellent. Due to the fact the cemented carbide layer 11 satisfies the given thickness mentioned above, the composite material 10 is difficult to deform.
    • 本发明提供了一种在硬质合金层和金属陶瓷层之间的接合能力优异的复合材料,并且可以抑制烧结后的变形,以及具有含有复合材料的基材的涂层切削工具。 通过层叠硬质合金层11和金属陶瓷层12并且在表面侧具有硬质合金层11来获得复合材料10ii。 两层11,12之间的边界具有凹部23,凹部23的最大深度Dmax为50μm以上且500μm以下。 当复合材料的厚度定义为h1,硬质合金层11的厚度定义为h2时,h2 / h1在大于0.02和0.4以下的范围内。 通过将凹部23设置在边界上,层11和12都被充分地结合,并且它们之间的结合能力优异。 由于硬质合金层11满足上述给定的厚度,复合材料10难以变形。
