Surface Microcracks of CMC
문제 현상
Microcracks of 0.05-0.2mm appear on the surface of CMC products, affecting appearance and strength
원인 분석
Internal stress of CMC products is too large, exceeding the material yield stress; environmental stress cracking; product design stress concentration
해결 방법
1)Annealing treatment to release internal stress; 2)Product design to avoid sharp corners and stress concentration; 3)Select high-molecular-weight CMC to improve crack resistance
핵심 요약
Microcracks are caused by excessive internal stress; annealing and crack-resistant design are the key
