microplough and breakage of plastic deformed ridges andwedges under the impact energy of 0.7 J. When the impactenergy is 1.2 J, it is microplough and secondary microcutting

in a short time. With the extension of test time, the wearmechanism changed to spelling of the plastic deformedridges and wedges. When the impact energy is 1.7 J, the wearmechanism is mainly the spalling of the work-hardeninglayer after a long time testing.
