권장 SiC 등급 및 조성

Choosing the right SiC grade is crucial for optimal performance. Different manufacturing processes yield distinct SiC types, each with specific properties:

• 반응 결합 실리콘 카바이드(RBSiC): Produced by infiltrating a porous carbon preform with molten silicon. RBSiC is known for its high strength, excellent thermal shock resistance, and good oxidation resistance. It’s often used for large, complex shapes and structural components.
• 소결 실리콘 카바이드(SSiC): Formed by sintering fine SiC powder with non-oxide additives at high temperatures. SSiC boasts very high purity, exceptional hardness, and excellent chemical resistance, making it ideal for mechanical seals, bearings, and semiconductor applications.
• 질화물 결합 실리콘 카바이드(NBSiC): Manufactured by reacting silicon powder with nitrogen to form silicon nitride bonds between SiC grains. NBSiC offers good thermal shock resistance and moderate strength, often used in refractory applications.
• CVD 실리콘 카바이드(CVD SiC): Created by chemical vapor deposition, resulting in ultra-high purity and density. CVD SiC is preferred for critical semiconductor and aerospace applications requiring extremely fine grain structures and precise control over material properties.

Understanding these grades allows engineers to select the most suitable material for their specific design and operational needs when seeking SiC for sale.

SiC 제품에 대한 설계 고려 사항

Designing with silicon carbide requires careful consideration due to its unique material properties. Key design factors include:

• 형상 제한: 응력 집중을 최소화하려면 날카로운 모서리, 얇은 벽, 갑작스러운 단면의 변화를 피하세요.
• 벽 두께: Optimize wall thickness to balance strength, weight, and thermal performance. Extremely thin walls can be challenging to manufacture and fragile.
• 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 potential stress points during operation and design to distribute loads evenly.
• 허용 오차: While SiC can achieve high precision, specifying overly tight tolerances can increase manufacturing costs.
• 가공성: SiC is extremely hard, requiring specialized diamond grinding for shaping. Design for features that are amenable to this process.

Collaborating with experienced manufacturers during the design phase can significantly improve the final product’s performance and manufacturability. For more on design, check out our 사용자 지정 지원.

공차, 표면 마감 및 치수 정확도

Achieving precise tolerances and optimal surface finishes is critical for the performance of 맞춤형 실리콘 카바이드 부품. While SiC is a hard material, advanced machining techniques allow for impressive accuracy:

• 달성 가능한 허용 오차: Depending on the part size and complexity, tolerances can range from $pm0.025 text{ mm}$ to $pm0.1 text{ mm}$ or tighter for critical dimensions through advanced grinding and lapping.
• 표면 마감 옵션: Surfaces can be ground, lapped, or polished to achieve specific roughness values (e.g., $Ra$ values down to $<0.2 text{ µm}$ for critical sealing surfaces).
• 치수 정확도: Consistent dimensional accuracy is maintained across production runs through stringent quality control and precise manufacturing processes.

These capabilities ensure that SiC components integrate seamlessly into complex systems and perform as expected in demanding environments.

후처리 필요

To further enhance performance and durability, some SiC components may undergo post-processing steps:

• 그라인딩 및 랩핑: Essential for achieving tight tolerances and fine surface finishes.
