Abstract
The advanced design of the video inspection system GeoKam for optical inspection of deep boreholes requires the joining of a transparent ceramic window to the Inconel® 718 housing. Active brazing using Incusil ™ ABA as active brazing material gave the best results. Detailed design calculations were performed using the codes ABAQUS® and STAU. Design optimizations resulted in the construction of a sleeve as an adapter part between the ceramic and the Inconel® 718 housing. An important result of the calculations was to avoid sharp edges of the sleeve by realization of a chamfer in order to reduce the fracture probability. The results of the design calculations could be verified with model experiments.
期刊介绍：
The Journal of Ceramic Science and Technology publishes original scientific articles on all topics of ceramic science and technology from all ceramic branches. The focus is on the scientific exploration of the relationships between processing, microstructure and properties of sintered ceramic materials as well as on new processing routes for innovative ceramic materials. The papers may have either theoretical or experimental background. A high quality of publications will be guaranteed by a thorough double blind peer review process.
