| 目的 制备高硬度、高耐磨性、自润滑及高热稳定性的AlCrBN/AlCrSiN纳米晶多层复合涂层，探索涂层的微观结构、力学性能、耐磨性能及高温热稳定性能。方法 采用多弧离子镀技术在WC-Co硬质合金以及不锈钢基底上，制备AlCrBN/AlCrSiN多层纳米晶复合涂层。采用扫描电子显微镜、X射线衍射、透射电子显微镜、纳米压痕仪等设备，对涂层在不同温度(600~1000 ℃)下退火前后的表面形貌、微观结构、力学性能、耐磨性能进行系统研究。结果 AlCrSiN/AlCrBN涂层为典型的纳米晶复合多层结构，涂层主要由fcc-AlCrN纳米晶镶嵌在非晶的SiNx和BNx中并形成多层结构。涂层具有优异的热稳定性能，其结构能够保持到800 ℃不发生变化，当温度增加到900 ℃时，涂层发生调幅分解，形成c-AlN、hcp-AlN和Cr2N等复合结构，在1000 ℃退火后，涂层结构基本稳定，仍能检测到CrN相。涂层纳米硬度及平均摩擦因数分别为29.15 GPa和0.67。结论 AlCrSiN/AlCrBN涂层具有优异的力学性能、耐磨性能及高温热稳定性能，在800 ℃以下保持稳定，在1000 ℃退火后仍能保持较高的硬度及良好的耐磨性能，在高速切削刀具中具有良好的应用前景。 |

| To extend the service life of cutting tool, AlCrBN/AlCrSiN nanocrystalline multilayer composite coating with high hardness, high wear resistance, self-lubrication and high thermal stability was prepared on the cemented WC-Co carbide and stainless steel substrate by multi-arc ion plating technology. The morphology, structure, mechanical properties and wear resistance of the coating before and after annealing in the range of 600~1000 ℃ were systematically studied by scanning electron microscopy, X-ray diffraction, transmission electron microscopy, nano-indentation and friction and wear tester. The AlCrSiN/AlCrBN coating exhibits a typical nanocrystalline composite multilayer structure with fcc-AlCrN nanocrystals embedded in the amorphous SiNx and BNx. The coating has excellent thermal stability performance, and its structure can be maintained to 800 ℃ without change. When the temperature increases to 900 ℃, the coating undergoes amplitude modulation decomposition, forming structures such as c-AlN, hcp-AlN and Cr2N. The structure of coating is stable after annealing at 1000 ℃, since CrN phase also can be detected in the coating. The coating nanohardness and average friction coefficient are 29.15 GPa and 0.67, respectively. AlCrSiN/AlCrBN coating has excellent mechanical properties, wear resistance and high temperature thermal stability, remains stable below 800 ℃, and can still maintain high hardness and good wear resistance after annealing at 1000 ℃, and has good application prospects in the field of high-speed cutting tool coating. |
