Research on the wear mechanism of ceramic tool in turning of nickel-based superalloy GH4169

Advanced Science and Technology Letters, 2014
The dry cutting experiment for nickel-based high temperature alloyGH4169 was conducted with Al2O3- SiCw whisker toughening ceramic blade WG300 and Si3N4-Al2O3 ceramics (Sialon) blade SX9. The main wear mechanism of ceramic cutting tools were analyzed by means of observing the wear morphology about cutting tools with scanning electron microscope, and ...
