Description
Technical Field
The invention belongs to the field of new materials, and particularly relates to a preparation method of a high-temperature antioxidant carbon fiber toughened zirconia ceramic material and the high-temperature antioxidant carbon fiber toughened zirconia ceramic material.
Background
With the development of science and technology, the function of materials in various fields is more and more prominent, new materials are more and more important to discover and prepare, and the discovery of new materials is limited by various conditions such as chance, so that the preparation of new materials by using the existing materials and changing or adjusting the preparation process becomes an important requirement for the materials. In this respect, the composite material has incomparable advantages, and has various excellent properties which are not possessed by a single material. The ceramic matrix composite has excellent performances of high temperature resistance, wear resistance, corrosion resistance and the like, so that the ceramic matrix composite is widely applied to the field of aerospace.
The ceramic material has larger expansion with heat and contraction with cold, which can reduce the structural stability and the safety reliability of the heat-proof parts and weaken and even destroy the heat-proof and oxidation-resistant ablation capacity of the material. When the environmental temperature is increased or decreased, if the volume of the material is changed little or hardly under the influence of the temperature, the problems of cracks, stress concentration and the like caused by the shape or volume change of the material in the application process can be reduced. That is, if the thermal expansion coefficient of the material itself is small, the material will play a crucial role in the important research fields of aerospace, precision instruments and the like. According to the principle of composite materials, materials with positive and negative thermal expansion coefficients are compounded, and materials with low expansion, zero expansion and even controllable thermal expansion coefficients can be obtained. Most materials in life expand at high temperature and contract at low temperature, and the thermal expansion coefficients of the materials are positive. However, there are also a small fraction of materials that shrink at high temperatures and expand at low temperatures, i.e., exhibit "cold swell and thermal shrinkage," and their coefficients of thermal expansion are negative, i.e., have "negative thermal expansion. In the thirties of the twentieth century, the phenomenon of "cold swelling and hot shrinking" of materials was observed, such as the perovskite ferroelectric material PbTiO3, cordierite 2 MgO.2A 12O 3.5 SiO2, beta-eucryptite LiAlSiO4, zeolite, and the like. However, the negative expansion of these materials is not considered to be important because the temperature range in which the negative expansion phenomenon occurs is too narrow, or the negative expansion behavior is anisotropic, so that the materials are likely to be microcracked during thermal cycling, have poor thermal shock resistance, and the like, and are difficult to be put into practical use.
Because of high melting point, high fracture toughness and high-temperature strength, low density, oxidation resistance, thermal shock resistance and good chemical stability, ZrO2 has wide application in the field of materials, and can be used as a thermal insulation layer of a rocket, a cylinder sleeve and a piston top of an internal combustion engine, various nozzles, ceramic valves, continuous casting nozzles and crucibles in smelting, a high-temperature corrosion-resistant thermometer and the like. The absolute values of the thermal expansion coefficients of ZrO2 and ZrW2O8 are similar and no chemical reaction occurs, ZrW2O8 is added into ZrO2, and the low-expansion or zero-expansion ZrO2/ZrW2O8 ceramic matrix composite material is obtained through component blending, so that the influence of temperature change on the dimensional accuracy in the service process of aviation and spacecrafts can be further reduced, the accuracy of heat-proof parts is improved, the internal stress generated by high-temperature expansion in the high-temperature material is further reduced, the thermal shock resistance of the material is increased, and the ceramic matrix composite material has wide and potential application value in the aerospace field.
However, there is a need for further improvements in the mechanical properties, particularly toughness, of conventional ZrO2/ZrW2O8 ceramic matrix composites.
