Sputter Erosion Model of Arcing Contact Materials

IEICE Transactions on Electronics, 2007
The sputter erosion of arcing contacts is a very complex phenomenon, which is determined by the interaction between electromagnetic force, heat conduction and surface tension of liquid metal. A new model for evaluating the sputter erosion of electrodes is described in this paper, which is based on the electromagnetic forces against the molten pool ...

Subduction erosion and arc volcanism [PDF]

Nature Reviews Earth & Environment, 2020
Tectonic or subduction erosion refers to the removal of upper-plate material from the forearc at convergent margins. Subduction erosion has been suggested to represent a major process associated with the transfer of crustal material into the Earth’s mantle at subduction zones.
