Since decades now, porous, metallic foams are used for the melt filtration. It is expected that ceramic foams enable the use of substantially higher temperatures. On the basis of their low density, they are additionally suitable for, inter alia, lightweight constructions of filters, process technology and heat exchange.
Downtime for cost reasons should be avoided as far as possible in production. There is a big interest in determining the damage of components during the machine operation. Thereby, the analysis of fracto emissions of micro cracks is used.
For manufacturing, there has to be an avoidance of machine downtimes because of financial reasons. There is a big interest in determining the damage of components during machine operation. Thereby, the analysis of radio wave and/or micro wave emissions is used.
