M adds plasticizer and reinforcing agent;
(5) mist projection granulating: carrying out mist projection granulating in spray drying tower, obtains the pelletizing of normal distribution, wherein 40 mesh are to 100
80% for being granulated powder content and being greater than total amount between mesh, moisture content is less than 1%;
(6) dry-pressing formed: pelletizing obtained above progress is dry-pressing formed, it is pressurizeed using bidirectional hydraulic press, molding pressure
It is by force 30-40MPa;
(7) isostatic pressing: improving green density, under conditions of 200Mpa, continues 3-5min;
(8) be burnt into: 1500-1520 DEG C at a temperature of be burnt into, keep the temperature 2-5h.
It is 80:20, TiO that alpha-aluminium oxide powder and 3mol yttrium, which stablize the mass ratio of nano zirconium dioxide, in step (1)2Content
For 0.1-0.5wt%, the content of Ca-Mg-Si is 0.5-1wt%.
Ca-Mg-Si selects CaO-MgO-SiO2, CaO-MgO-SiO2The content of middle CaO is 18%-24%, and the content of MgO is
32%-40%, SiO2Content be 36%-45%.
Beneficial effects of the present invention: 1, crystal grain refinement, the crystalline substance of strict control matrix (aluminium oxide) and disperse phase (zirconium oxide)
Particle size, making zirconium oxide, more uniformly disperse has better toughening effect between aluminium oxide.
2, using dry-pressing-equal pressing forming technology, green volume density is improved, higher green volume density is conducive to produce
The sintering of product reduces the porosity of firing porcelain block.
3, TiO is added2And CaO-MgO-SiO2It is sintering aid, sintering temperature is effectively reduced;The present invention have toughness it is strong,
The advantages of wearability height, low manufacture cost.
Detailed description of the invention
Fig. 1 is the preparation method knot fracture toughness test figure of Zirconia reinforced alumina wear-resistant ceramic of the present invention.
Fig. 2 is the preparation method hardness test figure of Zirconia reinforced alumina wear-resistant ceramic of the present invention.
Fig. 3 is the preparation method relative density test chart of Zirconia reinforced alumina wear-resistant ceramic of the present invention.
Specific embodiment
Following further describes the present invention with reference to the drawings.
Embodiment 1
The preparation method of Zirconia reinforced alumina wear-resistant ceramic takes alpha-aluminium oxide powder and 3mol yttrium to stablize nano zirconium dioxide not
Same proportion, taking the two proportion respectively is the sample of 90:10,80:20,70:30,60:40, wherein TiO2It is done with Ca-Mg-Si system
Sintering aid, and by above-mentioned sample respectively using water as decentralized medium, it is mixed according to the ratio that solid content is 60%, and according to this hair
Bright preparation method prepares 4 kinds of different ZTA ceramics respectively, and 90:10 is denoted as A, and so on be denoted as B, C, D respectively, obtain
Its ceramic hardness of A, B, C, D4 kind ZTA arrived and toughness are as illustrated in fig. 1 and 2, and wherein the test of toughness is surveyed using single side notched beam
Method for testing, wearability are 45 ° of sandblasting test methods, and ball milling uses 5 tons of horizontal ball mills;It is sanded and uses 60L stick pin sand mill;Spray
Mist is granulated the pressure spray drying tower for using evaporation capacity 300kg/h;It is dry-pressing formed to use 200-400t bidirectional hydraulic press;Etc. quiet
Press uses cold isostatic press (maximum pressure 300MPa);Kiln is using 1600 DEG C of electric pushed bat kilns.
By Fig. 1 and 2 it is found that when it is 90:10 that alpha-aluminium oxide powder and 3mol yttrium, which stablize nano zirconium dioxide proportion, composition
ZTA ceramics hardness it is relatively high, but since its zirconium dioxide content is less, thus the test result of its fracture toughness compared with
Difference, ductile strength are poor;It when proportion is 80:20, is obviously improved when fracture toughness is with respect to 90:10, and its hardness lowers
Degree is smaller, and the effect of the acquirement of two item datas is preferable;When proportion is 70:30 and 60:40, fracture toughness effect is preferable,
But hardness relative to 80:20 when significantly decrease, therefore composite effect is undesirable;The present invention has a kind of user
Just, security performance height, easy-operating advantage.
Embodiment 2
The relative density of tetra- kinds of different ratios of A, B, C, D, phase are tested by changing sintering temperature on the basis of the above embodiments
The performance of the various aspects of ZTA ceramics is also directly affected to the height of density.On the one hand the raising of sintering temperature can be grain
Son provides enough energy, it is enable to form ZTA ceramics across potential barrier;Another aspect temperature increases, to increase diffusion
Coefficient is conducive to the movement and mass exchange of particle, so that sintered specimen be made to densify.Therefore respectively 1300 DEG C, 1400 DEG C,
1500 DEG C, be fired under the conditions of 1600 DEG C of sintering temperature, due to joined TiO2Sintering aid is done with Ca-Mg-Si system, benefit
It will form intergranular liquid phase at high temperature with it and promote the diffusion and transmission of substance, to reduce the sintering temperature of material.
As shown in figure 3, relative density of the ZTA ceramics under different sintering temperatures.From the figure 3, it may be seen that ZTA complex phase ceramic sample
Relative density increase with the raising of sintering temperature.At 1300 DEG C, the relative density of A is 75.72%;At 1400 DEG C
Relative density reaches 88.91%;When sintering temperature rises to 1500 DEG C, relative density is up to 97.26%.In different sintering temperature
In the case where degree, with the raising of sintering temperature, grain diameter is become larger, and stomata is reduced, the increase of grain diameter and stomata
Reduction help to improve the relative density of sample.But since ZTA ceramics are compound material, 1600 are reached in temperature
DEG C when, relative density is decreased obviously.And option b can be seen that when temperature reaches 1500 DEG C or so according to Fig. 3, phase
To density highest, the case where reaching highest 98.7%, will appear decline later, this is because being the oxidation because of intergranular distribution
Zirconium particle inhibits growing up for blapharoplast, and tiny particle is then unfavorable for the densification of material.In being total to for both factors
Under same-action, under certain sintering temperature, the relative density of sample just increases that be that zirconium oxide can achieve full with temperature
And state, the case where causing first increases and then decreases.
Embodiment 3
It is higher and resistance to using the hardness and fracture toughness relative performance of ZTA ceramics made of the proportion of 80:20 in above-described embodiment
Mill property is also obviously improved, and the ZTA ceramics of 80:20 is equally prepared using method of the invention, with existing 92 aluminium oxide
Ceramics compare test, and wherein fracture toughness is single side notched beam test method, and wearability is 45 ° of sandblasting test methods;It surveys
Test result is as shown in the table:
Upper table, it is apparent that the various aspects of performance of the ceramics of ZTA made of in this way is made pottery far beyond 92 aluminium oxide
The performance of porcelain, ZTA ceramics in zirconium oxide can undergo phase transition toughening, for nano composite ceramic, since there are nano particle meetings
Nano effect is generated, to improve the mechanical property of material.Nano particle is distributed in the crystal boundary of blapharoplast, inhibits the length of particle
Greatly, small grains can hinder the extension of crackle, and improve the mechanical property of material.The ZTA composite ceramic prepared in this way
Porcelain, the crystallite dimension of strict control matrix (aluminium oxide) and disperse phase (zirconium oxide), making zirconium oxide, more uniformly disperse is aoxidizing
Between aluminium, has better toughening effect.And dry-pressing-equal pressing forming technology is used, green volume density is improved, it is higher
Green volume density is conducive to the sintering of product, reduces the porosity of firing porcelain block.Add TiO2And CaO-MgO-SiO2System's sintering
Sintering temperature is effectively reduced in auxiliary agent;The present invention has the advantages that a kind of performance easy to use, safe is high, easy-operating, present invention tool
Flexible is strong, wearability is high, low manufacture cost advantage.
