Provided is a layer structure for forming a surface of a substrate, particularly a tool subjected to wear, and a substrate, particularly a tool, having the layer structure. The composition is [M o Si p AY q ] γ [N r C s O t ] δ, where (o + p + q) = γ, (r + s + t) = δ, and (γ + δ) = 100, 40 ≦ γ ≦ 60, and M includes at least one first hard layer of Al in the periodic table and at least one metal of the group consisting of elements of Group IIb, Vb, and VIb. In the layer structure, AY is selected from the group consisting of Mn, Fe, Co, Ni, Cu, Group IIb element, Main group Ia, IIa, IIIa element, and Lanthanoid element of the periodic table A layer structure characterized by being at least one element.
