Preparation method of aluminum oxide and silicon carbide and zirconium carbide nano whisker enhanced parting tool material
The invention belongs to the field of cutter materials, relates to a parting tool material, and particularly to an aluminum oxide and silicon carbide and zirconium carbide nano whisker enhanced parting tool material. The in-situ reacted aluminum oxide and silicon carbide and zirconium carbide whisker enhanced parting tool material powder is composed of aluminum oxide base material powder and aluminum oxide and silicon carbide and zirconium carbide whisker powder, which are uniformly mixed by adopting a mechanical mixing method, and the mixed powder is subjected to gradual heating degassing under the vacuum condition of 10 to 6 torrs after treated by cold compacting, and then is subjected to vacuum sintering for 1 to 4 hours under the condition of 50 to 200 Mpa and 1500 to 1600 DEG C. The enhanced nano whisker is narrow and small in diameter size, uniform in distribution, high in structure stability and free of pollution on the surface, and the strength, tenacity, hardness, abrasion resistance and good fatigue property of the parting tool material are remarkably improved.
