Tool life of AlTiN coating before and after annealing (, , in vacuum) as well as after duplex post-treatment (annealing and ion implantation by ions) under conditions of high-speed turning of 1040 steel (according to cutting conditions shown in Table II). SEM images of the worn rake surface of cutting tools indicate on significant reduction of adhesive interaction with workpiece material after the duplex post-treatment.
