设计并在高速钢刀具表面制备了AlCrN涂层、AlCrSiN多层复合涂层和AlCrSiN纳米复合涂层。采用掠入射X射线衍射（GIXRD）、X射线光电子能谱（XPS）、电子探针X射线微区分析（EPMA）、扫描电镜（SEM）和高分辨透射电镜（HRTEM）等分析手段，结合力学性能测试和切削试验，系统研究了涂层的微观结构。结果表明，AlCrN涂层主要由纳米晶fcc-CrN、hcp-AlN和fcc-（Cr，Al）N固溶体组成。除了这些纳米晶相外，AlCrSiN多层膜和纳米复合涂层中还观察到少量的非晶Si 3 N4相，具有较强的{2 0 0}择优取向。AlCrSiN涂层的调制周期（6 nm）远小于AlCrN涂层的调制周期（18 nm）。AlCrSiN涂层刀具的使用寿命与AlCrN涂层刀具相比提高了约40%，因为其具有更优异的机械性能（48 GPa硬度、1123 MPa韧性、52 N LC 2粘附强度和0.25平均摩擦系数）。在切削过程中，涂层刀具的早期磨损机制为磨粒磨损，中期磨损机制为粘着磨损。AlCrSiN涂层刀具的磨损量小于AlCrN涂层刀具。
In the present work, AlCrN coating and AlCrSiN multilayer and nanocomposite coating were designed and deposited on the surface of high speed steel (HSS) cutters. The microstructures of these coatings were investigated systematically by means of grazing incidence X-ray diffraction (GIXRD), X-ray photoelectron spectroscope (XPS), electron probe X-ray microanalysis (EPMA), scanning electron microscope (SEM) and high-resolution transmission electron microscope (HRTEM), in association with mechanical property measurement and corresponding cutting test. The results showed that the AlCrN coating mainly composed of nanocrystalline fcc-CrN, hcp-AlN and fcc-(Cr,Al)N solid-solution. In addition to these nanocrystalline phases, a few amorphous Si3N4phases were observed for the AlCrSiN multilayers and nanocomposite coating with a stronger {2 0 0} preferred orientation. The modulation period (6 nm) of the AlCrSiN coating was much smaller than that of the AlCrN coating (18 nm). The service life of the AlCrSiN coated tool increased approximately 40% longer in comparison with the AlCrN coated tool because of its more excellent mechanical properties (48 GPa hardness, 1123 MPa toughness, 52 N LC2 adhesion strength and 0.25 average friction coefficient). During the cutting process, the wear mechanisms of coated tools at the early stage and mid-stage were abrasion wear and adhesion wear, respectively. And the worn loss of AlCrSiN coated tool was less than that of AlCrN coated tool.
