Detection of Cracks in Si3N4 Base Ceramics Using Microfocus Radiography
The long term reliability of structural ceramic components is of major interest and concern to those involved in design, manufacturing, testing and use of such components [1,2]. Flaw population data generated at a high probability of detection and high confidence level using improved NDE technology undoubtedly provide a reliable method for safe design at a lower cost as illustrated by the concept in Fig. 1. The concept demonstrates that more flaws with smaller size distribution may be detected at higher probability/ confidence level (compare dotted areas under the two flaws distributions 1, 2) with the use of appropriate NDE techniques and technique development.
