Shock wave compacted, melt infiltrated ceramics
- TNO Prins Maurits Laboratory, P.O. Box 45, 2280 AA Rijswijk (Netherlands)
Using shock wave compaction followed by melt infiltration with aluminum, B{sub 4}C-Al and TiB{sub 2}-Al composites have been fabricated. The composites are fully dense and crack-free. They have a high (80-85 vol.%) ceramic content, which gives them good mechanical properties. Due to the infiltration with aluminum, they also have rather good conductive properties. This makes it possible to machine them using spark erosion, in order to obtain complex articles such as nozzles and dies. They are lightweight, an advantage for application in armor and fast turning spindles. In the present article, scanning electron micrographs of the fracture surfaces will be shown and some material properties will be presented.
