Silicon infiltration tooling

Abstract

The invention discloses a siliconizing tool, which is used for loading carbon-made workpieces and performing liquid phase siliconizing production. The siliconizing tool includes a container body, a support and a container cover, and the container body is provided with a concave cavity; The support is placed in the concave cavity to support the carbon workpiece, and the support is provided with an accommodating structure for accommodating silicon powder; the container cover is closed on the container body for sealing the cavity. In the embodiment of the present invention, a cavity is provided on the main body of the container, and a support member with an accommodating structure for accommodating silicon powder is placed in the cavity, so that the carbon workpiece is placed on the support member, and then the container cover is covered. body, the siliconizing process can be carried out, the support and the carbon workpiece are tightly pressed to achieve a good siliconizing effect, the supporting function and the containing function of the support are combined into one, and there is no residual silicon slag bonding after the reaction, which is convenient Cleaning, and at the same time can be siliconized evenly to reduce bias.

Description

Technical field [0001] The present invention relates to a tooling, in particular, to a silicone tool. Background technique [0002] The CC-SiC is a composite material with carbon fiber as a reinforcement to C and SiC. For C / C composites, the most important difference is that SiCs having excellent antioxidant properties and high hardness replacement of partial C matrix in C / C composites, thereby ensuring the mechanical properties of C / C composites. Change the antioxidant properties. Therefore, the C / C-SiC material has a series of excellent performance, high-proportion modulus, excellent high temperature mechanical properties, thermal stability, high thermal conductivity, and low thermal expansion coefficient, including high-grade strength, thermal stability, high thermal conductivity and low thermal expansion coefficient. The substrate is high, heat-resistant, anti-ablative, and low wear resistance to the harsh environment. [0003] There are three main types of CC-SiC: ch...
