SiC 제품에 대한 설계 고려 사항

Effective design is crucial for manufacturability and performance. When preparing your RFQ, consider the following design aspects:

• 기하학 &038; 복잡성: SiC is a hard and brittle material, making machining challenging. Keep designs as simple as possible. Avoid sharp corners, thin walls, and abrupt changes in cross-section.
• 벽 두께 균일성: Aim for consistent wall thicknesses to prevent warping and internal stresses during firing.
• 공차: Specify only the tolerances that are truly critical to the function of the part to avoid unnecessary machining costs.
• 달성 가능한 최소 벽 두께는 SiC 등급과 전체 부품 크기에 따라 다릅니다. 열 질량 또는 가스 흐름과 같은 기능적 요구 사항과 구조적 무결성의 균형을 맞추는 것이 중요합니다. Identify areas prone to thermal or mechanical stress and design for reinforcement or stress relief features.
• 조립 &038; 고정: Consider how the SiC part will integrate with other components. Are mounting holes or specific attachment features required?
• 표면 마감 요구 사항: Define the desired surface roughness based on the application, as finer finishes often require additional machining.

공차, 표면 마감 및 치수 정확도

Achieving precise tolerances and surface finishes in SiC components requires specialized equipment and expertise. Clearly defining these parameters in your RFQ is vital.

• 달성 가능한 허용 오차: While tight tolerances are possible, they increase manufacturing complexity and cost. Typical general tolerances for SiC can range from ±0.05mm to ±0.2mm, with tighter tolerances achievable through grinding and lapping.
• 표면 마감 옵션:
  • As-fired/Rough: Suitable for non-critical surfaces, generally a matte finish.
  • 연삭된 상태: Achieved through abrasive grinding, offering improved flatness and surface roughness (Ra values typically around 0.8 μm – 3.2 μm).
  • 랩핑/연마된 상태: For precision surfaces, optical applications, or sealing surfaces. Achieves very low surface roughness (Ra values below 0.1 μm).
• 치수 정확도: Depending on the complexity and size of the part, dimensional accuracy can vary. Always provide 2D or 3D CAD models (e.g., STEP, IGES, SolidWorks) with your RFQ to ensure unambiguous interpretation.

SiC 부품의 후처리 요구 사항

After initial manufacturing, some SiC components may require further processing to meet specific performance criteria or integrate into complex systems.

• 그라인딩 &038; 랩핑: Essential for achieving tight tolerances, precise flatness, and desired surface finishes.
• 봉인: For porous SiC types (like RBSC or NBSC), sealing with glass, polymer, or another ceramic can improve impermeability.
• 코팅: Applying a protective coating (e.g., CVD SiC, pyrolytic carbon) can enhance surface hardness, erosion resistance, or chemical inertness for specific applications.
• Joining & Bonding: Techniques like brazing, diffusion bonding, or adhesive bonding may be used to join SiC components to themselves or dissimilar materials.
• 검사 &038; 테스트: Non-destructive testing (NDT) methods like ultrasonic testing, dye penetrant inspection, or X-ray radiography ensure structural integrity and defect detection.

일반적인 문제와 이를 극복하는 방법

Working with SiC presents certain challenges due to its inherent properties. Addressing these proactively in your design and RFQ can save time and resources.

• 취성: SiC is hard but brittle, making it susceptible to chipping or fracture under impact or tensile stress. Design with generous radii, avoid thin edges, and consider compressive loading where possible.
• 기계 가공 복잡성: Its extreme hardness makes conventional machining difficult and costly. Near-net-shape manufacturing processes are preferred, with grinding used for final precision.
• 열충격 민감도(특정 등급의 경우): While generally good, rapid temperature changes can still induce stress. Design for uniform heating/cooling, and select SiC grades with superior thermal shock resistance if this is a critical factor.
• 고온 소결: The very high temperatures required for sintering SiC can lead to shrinkage and warpage if not controlled precisely. This highlights the importance of experienced manufacturers.
• 비용: SiC components can be more expensive than traditional materials. Justify the cost by highlighting the long-term benefits in terms of performance, lifespan, and reduced maintenance.

올바른 SiC 공급업체를 선택하는 방법

Selecting a reliable and experienced SiC supplier is as crucial as the RFQ itself. A reputable partner can offer design guidance, material expertise, and consistent quality.
