Abstract
A method for preparing a flaky AlON/cubic-phase ZrO2 composite material is characterized in that flaky AlON powder and cubic-phase ZrO2 powder are compounded and fired into the flaky AlON/cubic-phase ZrO2 composite material in a hot-pressing manner after being subjected to cold isostatic press moulding, wherein the cubic-phase ZrO2 powder is calcium oxide fully stabilized zirconia powder. The flaky AlON/cubic-phase ZrO2 composite material prepared by the method has machinable ceramic property, the flaky AlON/cubic-phase ZrO2 are uniform in phase distribution and controllable in content, and the machinability, the mechanical property and the thermal property are favorable.
Description
Technical field
The present invention relates to a kind of sheet AlON/ Emission in Cubic ZrO
2matrix material, belongs to ceramics processing field.
Background technology
Stupalith has many good performances, still, because stupalith hardness is large, while preparing precise measure ceramic component, only has by diamond abrasive wheel grinding, and manufacturing cost is very high.So people are finding a kind of method always, can meet basic mechanical performance requirement and can carry out again mechanical workout and obtain the method for precise measure ceramic component.The nineties in 20th century, the people such as Japanese scholars Niihara adopt Si
