Process useful for wire arc spraying of workpieces, especially hollow bodies using wires made from different materials gives improved coating quality combined with shorter coating time

摘要

Process for wire arc spraying of workpieces, especially hollow bodies, in which at least two metal wires serving as melting electrodes are melted at the end by the electrode arc and the molten metal is thrown by a gas stream onto the workpiece surface. At least two wires made from different metals can be used.
