Copper coating of aluminium contact surfaces using magneto-plasma accelerator

The urgency of the task of copper drawing covering on aluminium surfaces is proved. For this purpose, the use of pulse magneto-plasma accelerator with high-current by the category such as Z-pinch is shown. In atmospheric conditions, the copper coverings of ∼100 microns-thick on aluminium samples are received. The high adherence, which is caused by the formation of a boundary layer of mutual mixture, influence the hypervelocity of a flow of copper plasma on an aluminium surface. The decision for the overlapping high-current problem of contact pair Cu-Al and significant reduction of its transitive contact resistance is experimentally shown as the copper coating is put on an aluminium surface with the help magneto-plasma accelerator.
