Laminated hard film and cutting tool
A laminated hard coating comprising a layer A and a layer B, wherein the layer A and the layer B differ in composition and are laminated. Layer A contains (MaAlbCrcTad)(BxCyNz) and satisfies 0≤a≤0.35, 0.05≤d≤0.35, 0≤x≤0.15, 0≤y≤0.50, a+b+c+d=1, and x+y+z=1. M is at least one element selected from the group consisting of V, Nb, Mo, and W; a, b, c and d represent the atomic ratios of M, Al, Cr, and Ta, respectively; and x, y, and z represent the atomic ratios of B, C and N, respectively. The layer B comprises (TiαSiβ)(BxCyNz) and satisfies 0.05≤β≤0.35, 0≤x≤0.15, 0≤y≤0.50, α+β=1, and x+y+z=1. α and β represent the atomic ratios of Ti and Si, respectively, and x, y, and z represent the atomic ratios of B, C, and N, respectively. One or more layers of each of these layers have been alternately laminated.
