The Analysis of Coating Quality of Thin Copper Film Prepared by Wire Exploding Spray Coating Method

摘要

Wire Exploding Spray Coating (WESC) technology is capable to prepare metal coating on nonmetal surface, such as glass, ceramic, etc. In order to determine the relationship between the technological parameters and the coating quality, experimental samples of WESC under different technological parameters are measured and analyzed in this paper. The results demonstrate that, during the WESC process, when the initial capacitor voltage increases from 10 to 20 kV, the metal wire diameter decreases from 1 to 0.5 mm, the circuit conductance decreases from 10.8 to 3.9 μH, the wire is heated up more sufficient, the mean diameter of metal micro-particle generated by the exploding is smaller, and the temperature and speed of the particles are higher, and the prepared coating is more compact, dense and even.
