摘要:A type of Si_3N_4-based nanocomposites ceramic cutting tool material was prepared by the addition of nano-scale Si_3N_4W whisker and nano-scale TiN particle. Cutting performance of the Si_3N_4/Si_3N_(4W)/TiN nanocomposite ceramic tool in machining of cast iron was investigated in comparison with a commercial sialon ceramic tool, and the tool wear mechanism was studied. The two types of cutting tools have similar cutting performance at relatively low cutting parameters, while Si_3N_4/Si_3N_(4W)/TiN nanocomposite tool exhibits a better wear resistance than sialon tool at the relatively high cutting parameters. The wear of sialon ceramic cutting tool is dominated by the plastic deformation, abrasive action, microcracking, pullout of grains and chemical action at the higher cutting parameters. The higher mechanical properties, and the refined matrix grains, intragranular TiN grains and dislocation in the microstructure improve the resistances to plastic deformation, microcracking, and pullout of grains for Si_3N_4/Si_3N_(4W)/TiN nanocomposite ceramic cutting tool. The wear of Si_3N_4/Si_3N_(4W)/TiN nanocomposite ceramic cutting tool is dominated by the abrasive and chemical actions at the higher cutting parameters.
