Liu, H: Near Net Shape Forming of Advanced Structural Cerami

This book provides valuable information on the making of complex-shape monolithic energy devices. The author discussed a new technology that combined rapid prototyping techniques and ceramic gelcasting processes in the and manufacturing of advanced structural ceramic components that cannot be fabricated by other shape-forming processes. The fabricated micro gas turbine rotors, micro inlet nozzles, mesoscale burner arrays, and micro heat exchangers have demonstrated superior shape accuracy, mechanical strength, and surface smoothness with a feature size less than 200 um. The concepts and functionalities of the ceramic devices were verified with performance tests. The shape complexity and surface quality of monolithic ceramic parts have been further improved through the use of novel mold assembly methods and new materials. A complete shape forming process (from slurry to final functional parts) was developed and introduced.
