  • Patent number: 8409696
    Abstract: A cutting tool includes a body of a hard alloy of cemented carbide, cermet, ceramics, cubic boron nitride based material or high speed steel and on which at least one of the functioning parts of the surface thereof, a hard and wear resistant coating is applied. The coating includes a polycrystalline laminar, multilayered structure of metal nitride compounds, in a repetitive form . . . MeN/(Ti1-xAlx)N/MeN/(Ti1-xAlx)N/MeN/(Ti1-xAlx)N/MeN/(Ti1-xAlx)N . . . of cubic structured (Ti1-xAlx)N layers where 0.3<x<0.95 and cubic structured MeN layers where Me is one or more of the metal element Ti, Zr, Hf, V, Nb, Ta, Mo and Al. The laminated structure has a repeat period, ?, of 5 nm??<20 nm, a layer thickness relation of 1/10<(dMeN/d(Ti,Al)N)<1/3 and a thickness dMeN?1 nm that is essentially constant throughout its total thickness up to 20 ?m.
