Abstract
The present invention provides a T6-type carbon nano-modified silicon carbide ceramic-based composite material. The material is prepared by the following steps: firstly, T6-type carbon nano powders and silicon carbide ceramic powders are mixed up; secondly, water and a dispersing agent are added into the above mixed materials; thirdly, an obtained mixture is stirred and ground to obtain a composite slurry; fourthly, the composite slurry is subjected to spray-drying and granulating to prepare spherical particles. In the composite material, the content of T6-type carbon nano powders is 10-15%. According to the technical scheme of the T6-type carbon nano-modified silicon carbide ceramic-based composite material, the silicon carbide ceramics is modified by T6-type carbon nano powders, so that the mechanical machining performance of the silicon carbide ceramics is improved.
Description
Technical field
The present invention relates to a kind of T6 type carbon nanometer-modification carbon/silicon carbide ceramic matrix composite, belong to ceramic material technology neck
Territory.
Background technology
As structural material applications widely, its excellent properties such as hardness is high, intensity is high, antioxygen for silicon carbide ceramics
Change and corrosion-resistant very prominent, rising especially as high-temperature material.But obtain the carbonization of good properties at high temperature
The technique of silicon pottery is often more complicated, and cost is also higher.
SiC ceramic not only has excellent ambient temperature mechanical properties, such as high bending strength, excellent non-oxidizability, good
Corrosion resistance, high wear-resistant and low coefficient of friction, and mechanical behavior under high temperature (intensity, creep resistance etc.) is known
In ceramic material optimal.Hot pressed sintering, pressureless sintering, the material of HIP sintering, its elevated temperature strength can be maintained to
1600 DEG C, be the material that in ceramic material, elevated temperature strength is best.Non-oxidizability is also best in all non-oxide ceramicses.
SiC ceramic obtains at industrial circles such as oil, chemical industry, microelectronics, automobile, space flight, aviation, papermaking, laser, mining industry and atomic energy
It is widely applied.
The shortcoming of SiC ceramic is that fracture toughness is relatively low, i.e. fragility is relatively big, is this complex phase with SiC ceramic as base in recent years
Pottery, such as fiber (or whisker) reinforcement, out-phase is dispersed particle-strengthened and function-graded material occurs in succession, improves monomer
The toughness of material and intensity.
Content of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, provide a kind of T6 type carbon nanometer-carbon modified SiClx pottery
Porcelain based composites.
The T6 type carbon nanometer-modification carbon/silicon carbide ceramic matrix composite of the present invention, makes, by the following method by T6 type carbon
After nano-powder and Silicon Carbide Powder mixing, after adding water, dispersant, stirring grinding becomes composite mortar, by being spray-dried
Spheric granules is made in granulation, and in described composite, the content of T6 type carbon nanometer is 10-15%.
Described dispersant is PEG400 or PEG600.
The T6 type carbon nanometer-modification carbon/silicon carbide ceramic matrix composite of the present invention, by T6 type carbon nano modification carborundum
Pottery, enhances the machining property of silicon carbide ceramics.
