Abstract
We consider the features of the deposition of a copper coating on a nickel substrate by the method of the electrical explosion of a foil in an external pulsed magnetic field. Investigations of the effect of the phase shift of the external magnetic-field pulse with respect to the moment of explosion on the morphology of the resulting coating are carried out. Deposition is carried out on the modernized experimental unit “INGIR-Mega-15” for five different conditions: the explosion occurred 100 μs before application of the magnetic-field pulse; it happened simultaneously with application of the magnetic-field pulse; at the middle of the leading edge of the pulse, at the maximum of the pulse, and at the middle of the rear edge of the pulse. The effect of the magnetic-field-pulse phase shift relative to the moment of explosion on the rate of the formation and decay of the plasma cloud is established. It is shown that the application of a magnetic field at the moment corresponding to the phase of the vapor-gas condensate promotes a more uniform distribution of copper drops over the wafer and a change in their shape.
