Abstract:
The experiments for spraying WC-Co ceramic foils were carried out in air environment using the ultrahigh-velocity electro-thermal explosion directional spraying device developed by ourself. The elementary process of electro-thermal explosion technology was studied. The energy-utilization ratio during explosion was calculated, The characteristics of electric parameters, like current, voltage and power during explosion were analyzed in detail. The results showed that the energy-utilization ratio of metal foils was about 33.4 %.
Key words:  electro-thermal explosion,ultrahigh-velocity spraying,energy-utilization ratio,WC-Co
