Abstract
The invention discloses a production method of a ceramic cutter. The method comprises the following steps: 1, carrying out pre-compression molding on a powdery raw material, wherein the powdery raw material comprises, by weight, 92-95 parts of zirconium oxide, 5-6 parts of yttrium oxide and 4-6 parts of rare earth oxide; 2, carrying out low-temperature heat treatment on the obtained pre-compression molded product at 1000-1100 DEG C; and 3, carrying out hot press vibration sintering on the low-temperature heat treated product, wherein the hot press vibration sintering temperature rises to 1700 DEG C from 1100 DEG C according to a heating rate of 30-50 DEG C/h, and the pressure rises to 100 MPa from 80 MPa. The ceramic cutter produced through the production method of the ceramic cutter has the advantages of high strength, and difficulty in fracture.
Description
Technical field
The present invention relates to a kind of preparation method of sintex.
Background technology
Compared with other cutter material, the most significant shortcoming of sintex is exactly that fracture toughness is not enough, flexural strength and
Thermal shock resistance is poor, when cutting temperature changes, easily cracks.Important as its resisting breakage ability of evaluation
One of index, pottery needs to improve its hardness, bending strength and fracture toughness by suitable means, and is carrying out civilian pottery
During porcelain cutter articles for use, the other forms of sintex and tableware are easy to burst apart, unfilled corner, and the fracture toughness of ceramic cutting tool material is more
For important.
Content of the invention
The present invention has designed and developed a kind of preparation method of sintex, and the intensity of prepared sintex is higher, is difficult
Fracture.
The present invention provide technical scheme be：
