| 摘要 |
<p>The invention relates to a multi-layered hard material coating for tools for machining purposes having a multi-layered structure in order to improve the wear and tear of tools, comprising at least one (Al<sub>y</sub>Cr<sub>1-y</sub>) X layer (0.2 = y = 0.7), wherein X is one of the following elements N, C, B, CN, BN, CBN, NO, CO, BO, CNO, BNO, CBNO, preferably, N or CN, and/or a (Ti<sub>z</sub>Si<sub>1-z</sub>) X layer (0.01 = z = 0.3). The hard material coating also comprises at least one layer packet comprising a (AlCrTiSi) X mixed layer, followed by one additional (Ti<sub>z</sub>Si<sub>1-z</sub>) X layer, followed by one additional (AlCrTiSi) X mixed layer, followed by one additional (Al<sub>y</sub>Cr<sub>1-y</sub>) X layer.</p> |
