TensioTOM – High temperature tensiometer
wetting behavior of metal melts

Visualizing the dynamic wetting behavior
of metal melt at high temperature

CeDeD has developed and built a unique measuring device to customers' specifications, the high temperature tensiometer TensioTOM. On the basis of the proven thermo-optical measuring devices (TOM), it is possible for the first time to monitor the dynamic wetting behavior of metal melts at high temperatures of up to 1700 ° C. In an ultra-pure atmosphere and with 0.5 µm resolution, a high-speed camera tracks the behavior of molten metal.
With the so-called sessile drop method, up to 5 drop placements can take place in one experiment. This enables product and process improvements in metallurgy and other industries with high temperature processes.
