Arc spraying is a thermal spray coating process that uses an electric arc to melt metal wires. These wires are fed into the arc, where they are heated to a molten state and then atomized into fine droplets. The droplets are propelled onto a surface, forming a protective or functional coating. This technique is commonly used for corrosion protection, wear resistance, and thermal insulation. It can apply various materials, including zinc, aluminum, and copper, making it versatile for different industrial applications. Arc spraying is valued for its efficiency and ability to create strong, durable coatings.
