<p>A surface coated member and its manufacturing method are provided. The member has a substrate and a coating layer on the substrate surface. A plurality of first phases and a second phase exist in the coating layer surface. The first phases are composed of at least one compound containing at least one element selected from metals in Groups 4, 5 and 6 of the periodic table, aluminum and silicon, and oxygen. The second phase is composed of at least one compound selected from carbide, nitride and carbon nitride of at least one element selected from the abovementioned metals, aluminum and silicon. A cutting tool includes the surface coated member and has a rake face on the upper surface, a flank face on the side surface, and a cutting edge at a crossed ridge portion between the rake face formed by at least the coating layer surface, and the flank face.</p> |
