Benefits of technology

[0031]The non-explosive method of metal and alloy degradation according to the present invention turns out to be better and more effective than the known, explosive method of metal (wire) degradation.

Problems solved by technology

However, intensive external cooling of the metal results in an increase of the critical currents mentioned herein.
The authors' experiments showed that even with the most efficient metal cooling, current density may not be infinitely increased.
It was observed that despite such effective cooling, short electrical impulses of high-density current cause an explosion.

Embodiment Construction

[0039]Longitudinal forces and the explosive degradation of wires: In the literature cited, published in Poland in 2001, it is shown that longitudinal forces occur in every conductor under the electrical current flow. Such forces are strictly quantum mechanical in character. The source of the longitudinal forces in metallic conductors is explained therefore in transfer of electrons which are colliding with the crystalline lattice of the conductor (phonons) as well as with impurities and structural metal crystal defects.

[0040]Conductor explosions as a source of nano-particles: Metallic conductors subjected to the high-density currents “break up into fragments”. This occurs when forces resulting from the collisions with metal ions exceed metal cohesive forces. The degrading metal forms an immense number of microscopic metallic fragments. The technique in which such a degradation takes place in a liquid medium is of particular practical importance. Metallic fragments formed as a result ...
