SURFACE-COATED CUTTING TOOL
摘要:
Provided is a surface-coated cutting tool combining superior heat resistance, superior wear resistance, and superior lubricity. A surface-coated cutting tool of the present invention includes a substrate and a coating formed on the substrate, and the coating is characterized in that the coating is formed by physical vapor deposition and includes one or more layers, that at least one of the one or more layers is a first coating layer, and that the first coating layer contains aluminum and nitrogen, has a thermal effusivity of 2,000 to 5,000 J·sec−1/2·m−2·K−1, has a thickness of 0.2 to 5 μm, and has a crystal structure including a hexagonal structure.
