摘要
Inspection methods to certify the reliability of large structural ceramic components composed of small blocks were studied. Ceramic blocks jointed with a silicon sheet or with glass were examined by UT and X-Ray. Silicon sheet or glass joints could be distinguished from other parts of component by UT more easily than by X-Ray. Fractures may originate in joints. More and larger defects were detected in non-joint parts and area than expected. It is important to develop technology to inspect joint layer deep within the sample. A new joint sample was developed, and its joint layer was inspected. It was found to have fewer defects in joints. Special probes were developed to inspect defects deep (95mm or deeper) within large components and were applied to large component samples. Defects of 0.5 mm were detected successfully.
