SiC 제품에 대한 설계 고려 사항

Designing custom SiC components requires a deep understanding of the material’s characteristics and manufacturing processes. Key considerations include:

• 형상 제한: SiC is a hard and brittle material, which impacts the complexity of achievable geometries. Sharp corners, deep grooves, and thin walls should be minimized to avoid stress concentrations and potential cracking during manufacturing or operation.
• 벽 두께: Uniform wall thickness is preferred to ensure even heating and cooling during sintering, reducing the risk of warpage or internal stresses. Significant variations in thickness can lead to manufacturing challenges.
• 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 and design around potential stress concentration points. Radius corners and smooth transitions are crucial to distribute stress effectively, especially in applications involving thermal cycling or mechanical load.
• 가입 및 조립: Consider how SiC components will be joined to other parts. Brazing, adhesive bonding, or mechanical fastening methods all have specific design implications for achieving robust assemblies.
• 가공 수당: While SiC can be machined, it’s a difficult process. Design parts to minimize the need for extensive post-sintering machining, and incorporate adequate allowances for grinding or lapping if precision surfaces are required.

공차, 표면 마감 및 치수 정확도

Achieving high precision with custom SiC components is possible, but it depends on the manufacturing method and subsequent finishing processes.

• 달성 가능한 허용 오차: As-sintered tolerances can vary, but for high-precision applications, grinding and lapping are employed. Precision grinding can achieve tolerances in the range of $pm 0.005$ mm to $pm 0.025$ mm, depending on the part size and complexity.
• 표면 마감 옵션: Surface finishes can range from an as-sintered matte finish to highly polished surfaces. Lapping and polishing can achieve surface roughness values as low as $R_a < 0.2$ $mu$m or even sub-nanometer levels for specific optical or sealing applications.
• 치수 정확도: Consistent dimensional accuracy is critical for component integration and performance. Advanced manufacturing techniques, coupled with stringent quality control, ensure parts meet the most demanding specifications.

후처리 필요

To enhance the performance and durability of custom SiC products, various post-processing steps may be necessary:

• 연삭: Precision grinding is essential for achieving tight dimensional tolerances and desired surface finishes, especially for mating surfaces or critical functional areas.
• 래핑: This abrasive machining process creates extremely flat and smooth surfaces, crucial for seals, bearings, and semiconductor components where minimizing friction and maximizing contact are important.
• 연마: For optical applications or ultra-smooth surfaces, polishing can achieve mirror-like finishes.
• 봉인: In certain applications, especially those involving porous SiC grades, impregnation or coating processes may be used to enhance impermeability.
• 코팅: Applying specific coatings can further enhance properties like wear resistance, corrosion resistance, or electrical insulation, depending on the application.

일반적인 문제와 이를 극복하는 방법

While SiC offers unparalleled advantages, working with it presents specific challenges:

• 취성: SiC is inherently brittle, making it susceptible to chipping or fracture under impact or tensile stress. Careful design (e.g., avoiding sharp corners, reinforcing critical sections) and proper handling are essential.
• 기계 가공 복잡성: Its extreme hardness makes SiC very difficult to machine, requiring specialized diamond tooling and techniques like EDM (Electrical Discharge Machining) for complex geometries. This can impact cost and lead time.
• 열충격: While resistant to high temperatures, rapid and extreme temperature changes can induce thermal shock, potentially leading to cracking. Designing for gradual temperature transitions or using SiC grades with higher thermal shock resistance can mitigate this.
• 비용: Custom SiC components can be more expensive than conventional materials due to raw material costs and complex manufacturing processes. However, their extended lifespan and superior performance often lead to a lower total cost of ownership.
