Abstract
A method for producing a coated cutting tool includes depositing a 0.5-10 μm nitride layer, which is a nitride of one or more of Ti, Zr, Hf, V, Ta, Nb, Si, Cr and Al, onto a substrate followed by depositing Al or Al+Me, further followed by depositing a 0.1-5 μm oxide layer being an (AlMe)Olayer, 0.05≤a≤1, wherein Me is one or more of Ti, Mg, Ag, Zr, Si, V, Fe, Hf, B and Cr, said layers being deposited by magnetron sputtering. Also, a coated cutting tool including a substrate with a coating having the nitride layer and oxide layer. The coating has inclusions of (Al,Me,O) in the oxide layer at the interface between the nitride layer and the oxide layer, and/or a layer of (Al,Me,O) situated in between the nitride layer and the oxide layer.
