| 目的 提高涂层刀具在高速工况下的切削寿命。方法 利用电弧离子镀技术在高速钢试样块和刀具表面制备不同弧电流（60、80、100 A）的AlCrBN涂层。采用扫描电镜（SEM）、X射线衍射仪（XRD）、X射线光电子能谱（XPS）、轮廓仪、洛氏压痕仪、划痕仪、显微硬度计、球盘摩擦磨损试验仪和切削试验对涂层的微观结构和性能进行研究分析。结果 AlCrBN涂层的物相成分为固溶的fcc-(Cr,Al)N相以及少量的CrB2和fcc-BN相。随着AlCrB靶弧电流由60 A增至100 A，表面粗糙度Sq值由197 nm增至208 nm，Sa值由107 nm增至113 nm；显微硬度由3574HK0.05先增至3890HK0.05，再降至3209HK0.05；结合强度Lc2由57 N增至63 N，再降至55 N，均呈现先增后减的趋势。不同弧电流制备的AlCrBN涂层的磨损率依次为0.69×10-15、0.38×10-15、0.84× 10-15 m3/(N•m)，涂层的磨损机理均为磨粒磨损、粘着磨损和氧化磨损。切削结果显示，AlCrBN涂层刀具在切削速度VC为60 m/min和191 m/min条件下的切削寿命均高于AlCrN涂层刀具，且80 A条件下制备的AlCrBN涂层刀具切削寿命均最长，分别为9 m和6 m。切削速度60 m/min条件下的磨损机理：初期为磨粒磨损，中期为磨粒磨损和粘着磨损，后期为粘着磨损。切削速度191 m/min条件下的磨损机理：初期和中期为磨粒磨损和粘着磨损，后期为粘着磨损。结论 AlCrBN涂层刀具与AlCrN涂层刀具相比，切削性能更加优越，并且80 A条件下制备的AlCrBN涂层的综合性能最优。 |

| The work aims to improve the cutting life of coated tools at high speed. AlCrBN coatings with various arc currents (60, 80, 100 A) were prepared on high speed steel samples and tools by arc ion plating technology. Microstructures and properties of the coatings were studied by scanning electron microscopy (SEM), X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), profilometer, scratch tester, microhardness tester, wear tester and cutting test. The phases of AlCrBN coatings were solid-soluble fcc-(Cr,Al)N phase and a small amount of CrB2 and fcc-BN phase. With the increase of arc current of the AlCrB alloy target from 60 A to 100 A, the surface roughness Sq of AlCrBN coatings increased from 197 nm to 208 nm, and the Sa increased from 107 nm to 113 nm. The microhardness increased from 3574HK0.05 to 3890HK0.05 and then decreased to 3209HK0.05. The adhesive strength Lc2 increased from 57 N to 63 N and then decreased to 55 N. The wear rate of AlCrBN coatings prepared under different arc currents was 0.69×10-15, 0.38×10-15 and 0.84×10-15 m3/(N•m) and the wear mechanism was abrasive wear, adhesive wear and oxidative wear. The cutting results showed that the cutting life of the AlCrBN coated tools under the conditions of VC=60 m/min and VC=191 m/min was higher than that of the AlCrN coated tools, and the cutting life of the AlCrBN coated tools prepared at 80 A was the longest, which is 9 m and 6 m respectively. Under the low cutting speed of VC=60 m/min, the main wear mechanism was abrasive wear in the initial stage, abrasive wear and adhesive wear in the middle stage, and adhesive wear in the final stage. Under the high cutting speed of VC=191 m/min, the main wear mechanism was abrasive wear and adhesive wear in the initial stage, abrasive wear and adhesive wear in the middle stage, and adhesive wear in the final stage. The AlCrBN coated tools show the superior cutting performance compared with the AlCrN coated tools. Moreover, the AlCrBN coating prepared at 80 A has the best comprehensive performance. |
