This study is focused on the usage of anti-wear layers based on carbon with the aim of improving the tool durability of sintered carbides composed of tungsten grains with cobalt as a binder (WC-Co) for wood-based material machining. The tested coating consists of a bottom TiAlN sublayer and a-CN top surface layer containing nitrogen-doped carbon. A TiAlN/a-CN double layer is deposited in an industrial DC magnetron sputtering system. The layers prepared in this way are examined with scratch and microhardness tests, as well as chemical analysis, in order to obtain the chemical composition of the coatings.. The standard exchangeable cutting blades made of sintered carbide are used in machining tests conducted on a CNC working centre. The machining properties of the double TiAlN/a-CN layer are shown to be superior in comparison to the standard tool.

这项研究的重点是基于碳的抗磨层的使用，目的是提高由钨晶粒与钴作为粘结剂（WC-Co）组成的烧结碳化物在木材基材料加工中的刀具耐久性。所测试的涂层由底部的TiAlN子层和包含氮掺杂碳的a-CN上表面层组成。在工业直流磁控溅射系统中沉积TiAlN / a-CN双层。通过刮擦和显微硬度测试以及化学分析来检查以此方式制备的涂层，以获得涂层的化学成分。.由烧结碳化物制成的标准可互换切削刀片用于在CNC上进行的机加工测试中工作中心。与标准工具相比，双TiAlN / a-CN层的加工性能显示出优越的性能。
