Abstract
We obtained the contact pair copper-aluminum copper coating by using a magneto plasma accelerator. The process is realized during supersonic copper plasma jet flowing into the chamber filled with the air atmosphere. Copper jet is carried out of the accelerating channel towards the aluminum target. Plasma jet is generated by coaxial magnetoplasma accelerator (CMPA) based on copper electrode system. The CMPA is supplied from the pulsed capacitive energy storage with the maximum value of stored energy of 360 kJ. The obtained copper-aluminum contact pairs have been analyzed by X-ray diffractometry and Nano hardness tester. The copper coating on the aluminum surface is uniform with thickness about 100 gm. Also in this paper it is shown that transitional contact resistance of copper-aluminum contact pair is at 2,5 times less than a direct connection of copper and aluminum (test contact pair).
