The main function of the siliconizing sintering furnace is to penetrate silicon into the carbon ceramic matrix to increase the hardness, wear resistance and corrosion resistance of the ceramic material . Specifically, the siliconizing sintering furnace achieves the penetration and solidification of the silicon element by diffusing it into the pores of the carbon ceramic matrix under high temperature conditions, and ultimately enhances the properties of the ceramic material 1.Use Siliconizing sintering furnaces are widely used in the following fields:
liquid phase siliconization of carbon carbon composites and ceramic matrix composites . This treatment can significantly improve the performance of the material, making it show better durability and stability in a variety of harsh environments, metal materials , ceramics and composite materials and other fields. Siliconizing can improve the physical and chemical properties of these materials to meet the needs of specific applications
2.Structural characteristics.
Siliconizing sintering furnaces usually have the following structural characteristics:
horizontal and vertical structure: including single door and double door design, suitable for different process requirements
2.double layer furnace structure: with water cooling jacket design to ensure the stability and safety of the furnace at high temperature
3.automatic operation: PLC and touch screen operation mode, with alarm function, simple and safe operation
Process flow
The process flow of siliconizing sintering furnace usually includes the following steps:
carbon fiber prefabricated matrix : The carbon ceramic matrix is prepared by high temperature cracking treatment and pressure impregnation.
silicon penetration : the carbon ceramic matrix is placed in an environment rich in silicon and heated to a certain temperature, so that the silicon element diffuses into the pores of the carbon ceramic matrix.
curing and crystallization treatment : the temperature is reduced for curing and crystallization treatment to ensure the stable presence of silicon in the ceramic matrix
