Abstract

Modifying the architecture from a monolithic to a multilayered structure allows adjusting the mechanical properties and cutting performance of industrially relevant hard coatings. The present work focuses on the microstructural, micro-mechanical and cutting performance evaluation of a multilayered TiC_0.67N_0.33/TiC coating grown by chemical vapor deposition. Energy dispersive X-ray spectroscopy and atom probe tomography confirmed the presence of individual TiC and TiC_0.67N_0.33 layers of ∼120 nm thickness with well-defined interfaces. The overall C/(C + N) ratio of the coating amounts to 0.82. Individual peaks for the TiC_0.67N_0.33 and the TiC layer can be observed in the X-ray diffractogram of the TiCN/TiC coating. Scanning electron microscopy showed that the grains grow through the interfaces between the TiCN and TiC layers. Finally, the micro-mechanical properties and cutting performance of the TiCN/TiC multilayer were compared with a monolithic TiCN coating. The fact that the TiCN/TiC coating outperformed the monolithic reference TiCN in regard of hardness and cutting performance emphasizes the high potential of multilayered coatings for use in demanding applications.

化学气相沉积 TiCN/TiC 多层涂层：涂层结构与机械性能之间的相互作用

将结构从单层结构改为多层结构，可以调整工业相关硬涂层的机械性能和切割性能。本研究的重点是对通过化学气相沉积法生长的多层 TiC0.67N0.33/TiC 涂层进行微结构、微机械和切削性能评估。能量色散 X 射线光谱和原子探针断层扫描证实了厚度为 120 nm 的单个 TiC 层和 TiC0.67N0.33 层的存在，且界面清晰。涂层的总体 C/(C + N) 比率为 0.82。在 TiCN/TiC 涂层的 X 射线衍射图中可以观察到 TiC0.67N0.33 和 TiC 层的单独峰值。扫描电子显微镜显示，晶粒通过 TiCN 层和 TiC 层之间的界面生长。最后，将 TiCN/TiC 多层涂层的微机械性能和切削性能与整体 TiCN 涂层进行了比较。事实上，TiCN/TiC 涂层在硬度和切削性能方面都优于单层参考 TiCN，这凸显了多层涂层在高要求应用领域的巨大潜力。

期刊介绍： The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
