Arc Spray is a thermal spray coating process that uses an electric arc to melt metal wires. The molten metal is then atomized and propelled onto a surface, creating a protective coating. This method is commonly used for repairing and enhancing the durability of various components in industries like aerospace and automotive. The process typically involves two metal wires, which are fed into a spray gun. An electric arc forms between the wires, generating heat that melts them. The resulting droplets are sprayed onto the target surface, forming a strong bond and improving resistance to wear, corrosion, and other environmental factors.
