Abstract
A kind of sheet AlON/TaB
2the preparation method of matrix material, is characterized in that, by sheet AlON powder and TaB
2ceramic powder is that 10 ~ 50:100 ratio mixes with weight ratio, and at the temperature of 1600 ~ 2000 DEG C, argon gas atmosphere hot pressing is fired and made sheet AlON/TaB in 30 ~ 180 minutes
2matrix material.Sheet AlON/TaB prepared by the present invention
2matrix material, has workability, sheet AlON, TaB
2entropy density deviation is even, content is controlled, and processability, mechanical property and thermal property are excellent.
Description
Technical field
The present invention relates to a kind of sheet AlON/TaB
2matrix material, belongs to field of ceramic preparation technology.
Background technology
Stupalith has many excellent performances, but because stupalith hardness is large, when preparing precise measure ceramic component, only have by diamond abrasive wheel grinding, manufacturing cost is very high.So people are finding a kind of method always, not only basic mechanical performance requirement can met but also the method that mechanical workout obtains precise measure ceramic component can be carried out.The nineties in 20th century, the people such as Japanese scholars Niihara adopt Si

3finding sheet AlON phase during binary solid solution, providing new approach for preparing processable ceramic.
Summary of the invention
The object of the invention is to for the preparation of processable ceramic provides a new approach.Its technological method is:
A kind of sheet AlON/TaB
2the preparation method of matrix material, adopts sheet AlON powder and TaB
2ceramic powder is that 10 ~ 50:100 ratio mixes with weight ratio, and at the temperature of 1600 ~ 2000 DEG C, argon gas atmosphere hot pressing is fired and made sheet AlON/TaB in 30 ~ 180 minutes
2matrix material, wherein, sheet AlON powder is AlN and Al
2o
3mol ratio be 2 ~ 5.
Compared with prior art, its advantage is in the present invention:
1, production sheet AlON/TaB of the present invention
2matrix material uniform microstructure, intensity is high, and global reliability is high;
2, prepared sheet AlON/TaB
2matrix material has good processability;
3, sheet AlON/TaB
2matrix material has excellent antioxidant property, mechanical property and thermal property.
