Abstract

The invention discloses a stainless steel/silicon carbide ceramic-based composite material and a preparation method thereof. The stainless steel/silicon carbide ceramic-based composite material is characterized by being prepared from the following raw materials in parts by weight: 60-70 parts of silicon carbide, 9-12 parts of stainless steel powder, 7-9 parts of titanium powder, 2-4 parts of starch, 3-5 parts of coal ash, 1-2 parts of titanate coupling agent; 10-15 parts of absolute ethyl alcohol, 3-4 parts of highly wearable carbon black, 1-2 parts of calcium stearate, 1-3 parts of liquid paraffin, 2-4 parts of sintering aid and 80-100 parts of deionized water; according to the stainless steel/silicon carbide ceramic-based composite material, the added stainless steel powder and the titanium powder are capable of improving the high temperature resistance, the corrosion resistance, the strength and the toughness of the silicon carbide ceramics, increasing the relative density of the material, improving the sintering performance and expanding the application range of the ceramics; and the method has the advantages of easily available raw materials, short period, reduction of the sintering temperatures, reduction of the cost, and conservation of resources.

Description

technical field [0001] The invention relates to a stainless steel / silicon carbide ceramic matrix composite material and a preparation method thereof, belonging to the technical field of ceramic production. Background technique [0002] Silicon carbide ceramics have the characteristics of high strength, high hardness, wear resistance, heat resistance, corrosion resistance to almost all chemicals, etc., and also have superior high temperature mechanical, thermal properties, radiation resistance and oxidation resistance. However, silicon carbide ceramics still have the disadvantages of brittleness and insufficient toughness, which limit the application of silicon carbide ceramics in aerospace, nuclear industry, large-scale petrochemical and other fields. Therefore, composite ceramic matrix materials are an effective way to improve the performance of silicon carbide ceramics. The stainless steel powder and titanium powder added in the invention improve the high temperature, co...
