铬硼以2,10和20 at为目标。以氮气为工作气体，在阴极电弧放电中加入%硼，在硬质合金刀片上沉积（Cr，B）N涂层。对目标材料的放电行为进行了表征。用辉光放电光谱法对涂层的化学成分进行了半定量分析，并在真空和大气条件下对样品进行了700°C回火前后的负载压痕测量，研究了涂层的热稳定性。以经过相同循环处理的TiN和CrxN涂层作为对照材料。在真空条件下回火证明（Cr，B）N和标准材料涂层具有几乎相同的稳定性。仅在大气条件下回火后，（Cr，B）N涂层对压头的穿透表现出几乎相同的响应。
Chromium-Boron targets with 2, 10 and 20 at.% boron are applied in a cathodic arc discharge with nitrogen as the working gas for the deposition of (Cr,B)N coatings on cemented carbide inserts. The discharge behaviour of the target material is characterized. The chemical composition of the coatings is semiquantitatively analysed by glow discharge optical spectroscopy The thermal stability of the coatings is investigated by load-indentation measurements prior to and after tempering of the samples at 700°C under vacuum as well as under atmospheric conditions. TiN and CrxN coatings treated in the same cycles served as reference materials. Tempering under vacuum conditions proves a nearly identical stability of the (Cr,B)N and the reference material coatings. After tempering under atmospheric conditions only, the (Cr,B)N coatings show a nearly identical response to the penetration of the indenter.
