Abstract

In this work, four AlCrBON coatings with various oxygen contents were fabricated. As the oxygen content increased, a phase transition from fcc-(Cr, Al)N to fcc-(Cr, Al)(O, N) occurred, the Al-O and Cr-O bonds increased while Al-N and Cr-N bonds reduced. The AlCrBON coating with a 13.4-atom% oxygen content (C2 coating) exhibited a high nano-hardness (39.6 GPa) and scratch adhesion (with L_c2 of more than 70 N), low high-frequency impact force (0.7 N), less delamination, and more cutting times (10 min under 80 m/min and 240 s under 100 m/min) against titanium alloy under both cutting speeds. Addition of O relieved the wear both on the flank face and rake face of the coated inserts against titanium alloy throughout the cutting process.

不同含氧量的 AlCrBON 涂层对钛合金的抗冲击性和高速干切削性能

在这项研究中，我们制作了四种不同氧含量的 AlCrBON 涂层。随着氧含量的增加，出现了从 fcc-（Cr，Al）N 到 fcc-（Cr，Al）（O，N）的相变，Al-O 和 Cr-O 键增加，而 Al-N 和 Cr-N 键减少。氧含量为 13.4-atom% 的 AlCrBON 涂层（C2 涂层）与钛合金相比，在两种切削速度下均表现出较高的纳米硬度（39.6 GPa）和划痕附着力（Lc2 超过 70 N）、较低的高频冲击力（0.7 N）、较少的分层和较长的切削时间（80 m/min 时为 10 分钟，100 m/min 时为 240 秒）。在整个切削过程中，添加 O 可减轻涂层刀片侧面和斜面对钛合金的磨损。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
