Abstract
Method for manufacturing a workpiece with wear protective coating starts with depositing a first hard material layer selected from the group consisting of TiN, TiCN, TiAlN, TiAlCN or the workpiece. Above the first hard material layer, a second hard material layer selected from the group consisting of TiN, TiCN, TiAlN, TiAlCN is deposited. The second layer is either deposited directly on the first layer or on a transition layer between the first and second layers. The transition layer is made of a material composed of the materials of the first and second layers, and has a thickness of between 5 nm and 500 nm. The first and second hard material layers have the same crystal structure, but different crystallographic privileged orientation with a value I(200)/I(111) between an intensity of the (111) plane, I(111), and an intensity of the (200) plane, I(200), of one of the first and second layers being at most 1 and the value of the other being at least 1. The values are thus different from each other.
