Description

Technical Field

[0001] The invention relates to the technical field of titanium diboride-carbon composite material processing, in particular to a pretreatment process and method for preparing the titanium diboride-carbon composite material. Background Art

[0002] In modern industry and technology, there is an increasing demand for materials with excellent comprehensive properties such as high hardness, high wear resistance, good electrical conductivity and high temperature stability. Titanium diboride itself has the characteristics of high melting point, high hardness, good electrical conductivity, etc., while carbon materials have good self-lubrication, high temperature stability and chemical stability. The combination of titanium diboride and carbon can combine the advantages of both, and it is expected to produce high-performance materials that meet the requirements of fields such as aerospace, electronics, and mechanical processing. For example, in the aerospace field, the braking device of the aircraft requires materials that can withstand high temperatures and high friction. The high hardness and good friction properties of titanium diboride-carbon composite materials make it a potential ideal material. In the electronics field, its good electrical conductivity can be used to manufacture high-performance electronic components and electrode materials.

[0003] The existing device mainly adopts cold pressing of the mixed powder after ball milling; then, the pressed green sheet is ignited by electric arc in a vacuum chamber to obtain the combustion product. The existing technology is similar to a pretreatment process and method for preparing titanium diboride-carbon composite material. The structure of patent number CN200910095175.4 includes at least TiB2, B4C, TiC and C. The present invention also provides a preparation method of titanium diboride-boron carbide-titanium carbide composite ceramic material, which adopts TiC and C as additives. The addition of C can remove B2O3 and TiO2 on the surface of TiB2 powder, avoid the obstruction of the oxide layer (TiO2, B2O3) on the surface of TiB2 powder, reduce the sintering activation energy, and improve the degree of densification. Through the addition of TiC, it reacts with B4C to form a new TiB2 phase, avoids the abnormal growth of TiB2 grains, improves the sintering performance of the composite ceramic material, improves the density, avoids the increase of residual stress of the material caused by grain growth, generates a large number of microcracks, and reduces the mechanical properties. The present invention increases the density of the composite ceramic material through the hot pressing sintering process, so that the composite ceramic material has the advantages of high efficiency, low sintering temperature, small grain size, high densification degree, close bonding between grains, and high comprehensive performance of the product. However, there are still areas for optimization of the device.

[0004] However, the existing devices have the following problems:

[0005] 1. The existing device mainly directly puts the material into the mold for pressing and sintering, so that the water contained in the material evaporates during the pressing and sintering process, affecting the quality of the sintered product.
