Disclosed are workpieces, especially those made of steel or hard metals, provided with at least two coatings of a wear-protective system, which qualities are improved even with high system thickness, so that adjoining coatings are realized with differing crystallographic privileged directions.

1. A workpiece with a wear-protective coating, the wear-protective coating comprising: a first hard material layer made of a material selected from the group consisting of TiN, TiCN, TiAlN, TiAlCN; a second hard material layer made of a material selected from the group consisting of TiN, TiCN, TiAl

1. A workpiece with a wear-protective coating, the wear-protective coating comprising: a first hard material layer made of a material selected from the group consisting of TiN, TiCN, TiAlN, TiAlCN; a second hard material layer made of a material selected from the group consisting of TiN, TiCN, TiAlN, TiAlCN; the second hard material layer being either directly deposited on the first hard material layer or a transition layer being between the first and second hard material layers, the transition layer being made of the materials of the first and second hard material layers, and the transition layer having a thickness of 5 nm to 500 nm; said first and second hard material layers having the same crystal structure, but different crystallographic privileged orientation, 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 said first and second hard material layers being at most 1, said value of the other of said first and second hard material layers being at least 1, said values being different from each other.
