Description

Technical Field

[0001] The utility model relates to the technical field of carbon-ceramic composite material preparation devices, in particular to a gas phase siliconization device for carbon-ceramic friction materials. Background Art

[0002] Carbon-ceramic composite materials have the advantages of low density, wear resistance, high friction coefficient, smooth braking, corrosion resistance, oxidation resistance, high temperature resistance, strong environmental adaptability (such as friction factors do not decay in wet state) and long life. It is an ideal new type of high-performance friction material. At present, there are four main processes for preparing carbon-ceramic composite materials: precursor impregnation-cracking process (PIP), chemical vapor infiltration process (CVI), liquid siliconization reaction sintering process (LSI) and gas siliconization reaction sintering process (GSI). The gas siliconization reaction sintering process has the advantages of adjustable composition, designable performance and easy post-processing. The gas siliconization reaction is roughly divided into two stages: in the first stage, after silicon vapor contacts carbon fiber, it adsorbs and reacts chemically to form silicon carbide, which wraps the surface of the fiber to form a thin layer and then reacts to the next stage; in the second stage, the reaction is a diffusion reaction of carbon and silicon in the silicon carbide layer. As the thickness of the silicon carbide layer increases and the reaction space continues to decrease, the reaction rate slows down until it stops, and the unreacted silicon matrix remains.

[0003] For example, the application number is CN202120994330.2. The utility model relates to the technical field of carbon-ceramic composite material preparation device, and discloses a gas phase siliconization device for carbon-ceramic friction material, including a reaction container, a support rod and a cover body. The cover body is arranged at the opening of the reaction container to form a sealed space. The interior of the reaction container is provided with a partition plate for separating the infiltration chamber and the evaporation chamber. The infiltration chamber is located between the evaporation chambers on both sides. The partition plate is provided with a plurality of through holes for connecting the infiltration chamber and the evaporation chamber. The support rod is arranged across the partition plates on both sides to support the workpiece to be vacated and placed in the infiltration chamber. Silicon particles are placed in the evaporation chamber. After the silicon particles are heated to a molten state, the gaseous silicon evaporates from bottom to top in the evaporation chamber, and then enters the infiltration chamber through the through hole. Different planes of the workpiece can simultaneously infiltrate sufficient gaseous silicon to react with part of the carbon matrix. The through hole plays a guiding role, and the reaction process is more uniform, so that the prepared carbon-ceramic composite material has a balanced component content and has the advantages of high friction stability.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that the silicon vapor of the gas phase siliconization device evaporates from bottom to top, that is, the silicon vapor on the bottom surface of the workpiece is the first to contact and the contact amount is the largest, the reaction rate of the bottom surface of the workpiece is the fastest, and after the reaction stops, the residual silicon matrix is ​​also the largest. The silicon penetration amount at different positions of the workpiece is uneven, which can easily cause the prepared carbon-ceramic composite material to have uneven components and easy cracking during use. However, during use, although multiple through holes can be used to ensure that the contact with the workpiece is more uniform, it is impossible to control the silicon vapor to be uniformly discharged through each through hole, resulting in that the silicon vapor that can be contacted by each part of the workpiece cannot be equally sufficient, thereby affecting the workpiece processing efficiency.
