Apparatus for wire explosion spray coating

摘要

Apparatus for a wire spray coating method including a capacitor connected with an electric power source to be charged thereby. A gap switch having discharge electrodes which are spaced apart from each other so that a discharge is produced under a voltage applied by the capacitor. Wire receiving terminals which are spaced apart to receive a length of wire of coating material therebetween, the terminals being connected with the capacitor so that the charge of the capacitor is applied to the terminals through the switch. The discharge electrodes being maintained at a fixed distance so that a discharge across the electrodes is readily produced when the electrodes are supplied with the voltage from the capacitor. A voltage dividing element for applying a fraction of the voltage across the capacitor to the discharge electrodes and the remainder of the voltage to the wire receiving terminals when the wire is not in position between the terminals, but for applying substantially a total voltage of the capacitor when the wire is in a position between the terminals.
