Abstract

With different charging energies, the wire voltages and currents were measured when the molybdenum wire explosions occurred and the coatings were sprayed on the aluminum alloy substrates. The measured voltages and currents were brought into calculating the deposited energies of the molybdenum wires. And the coatings were characterized by observing their cross sections with a Scanning Electron Microscope and testing their thickness, surface roughness and hardness. The results revealed that when the charging energy was higher, the growth rate and value of the deposited energy would be larger, the coating became denser and smoother, and the average thickness and the surface roughness were smaller, while the average hardness firstly increased, and then decreased with the ascension of the charging energy.
