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 Lc2 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.
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.
