Ontwerpoverwegingen voor SiC-producten

Designing custom SiC components requires a deep understanding of the material’s unique characteristics. Proper design can significantly impact performance, manufacturability, and cost:

• Materiaaleigenschappen: Account for SiC’s high hardness, brittleness, and excellent thermal conductivity during design.
• Geometrie Limieten: Avoid sharp corners, thin walls, and abrupt changes in cross-section, which can lead to stress concentrations and cracking during sintering or service.
• Wanddikte: Aim for uniform wall thicknesses where possible to ensure even heating and cooling during manufacturing.
• Spanningspunten: Identify potential stress points and reinforce them, considering the load and temperature profiles the part will experience.
• Bewerking beperkingen: SiC is extremely hard, making machining difficult and expensive. Design parts to minimize the need for complex post-sintering machining.

Tolerantie, Oppervlakteafwerking & Maatnauwkeurigheid

Achieving precise tolerances and optimal surface finishes is critical for the performance of custom SiC parts. The choice of manufacturing process and post-processing techniques directly influences these factors:

• Haalbare toleranties: Tighter tolerances generally increase manufacturing costs. Standard tolerances for SiC can range from $pm 0.5%$ to $pm 0.05%$, with super-precision components achieving even finer tolerances through advanced grinding and lapping.
• Opties voor oppervlakteafwerking: Surface finishes can range from as-fired (rougher) to highly polished (mirror-like), depending on the application’s requirements for friction, sealing, or aesthetics.
• Maatnauwkeurigheid: High dimensional accuracy is paramount for proper fit and function in critical assemblies, especially in semiconductor and aerospace applications.

Nabehandelingsbehoeften voor SiC-componenten

While SiC boasts exceptional inherent properties, certain post-processing steps can further enhance performance and durability:
