Hard coating, hard-coating coated tool, and production method for hard coating

A hard coating that is to be provided on a surface of a substrate so as to cover the surface of the substrate, wherein

• the hard coating includes a first layer to be disposed on the surface of the substrate and a second layer disposed on a surface of the first layer,
• the first layer is constituted by AlaCrbαcN, wherein atomic ratios a, b, c satisfy a+b+c=1, 0≤c≤0.40 and 0.25≤b/a≤1.0, and wherein an optional additive component α is at least one kind of element selected from groups IVa, Va and VIa (except Cr) and Y of periodic table of elements,
• the second layer is constituted by AlCreCN, wherein atomic ratios d, e, f satisfy d+e+f=1, 0.001≤f<0.20 and 0.25≤e/d≤1.0,
• a total thickness T as a sum of a thickness T1 of the first layer and a thickness T2 of the second layer is within a range from 0.5 μm to 9.0 μm,
• a ratio (T2/T) of the thickness T2 of the second layer to the total thickness T is within a range from 5% to 50%, and
• the hard coating including the first layer and the second layer has peaks belonging to (111) and (200) planes in an X-ray diffraction, such that an intensity ratio (SP1/SP2) of a peak intensity SP1 of the (111) plane to a peak intensity SP2 of the (200) plane is within a range from 0.1 to 20.
