Electric Wire Arc Spray
The arc spraying process sometimes also called as twin wire arc spray involves melting of two wires (the coating material) in an arc and accelerating them towards the prepared work surface by means of an atomizing gas such as compressed air. Arc spraying is a high-performance wire spraying process, but the coating material must be electrically conductive. Twin wires are fed via electric driven motor or air motor. Metal Coat manufactures both the type of equipment.
Electric arc spray coatings are normally denser and stronger than their equivalent combustion spray coatings. Low running costs, high spray rates and efficiency make it a good tool for spraying large areas and high production rates.
