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 measuring concentration of each element in wear tiny region lying in the ceramic tools with Energy Dispersive Spectrometer(EDS). The results show that the main wear mechanism of ceramic cutting tool was presented by cohesive wear, abrasive wear and oxidation wear. Cohesive wear occurs mainly on the rake face and were influenced by the contact stress state between the contact points of cutting tool and workpiece material.
