The copper spray metalizing gun is used for a thermal spray of copper over the surface of the substrate. The copper gun is used for coating after the sandblasting process. Before the copper spray metalizing with the copper thermal spray gun surface finishing is done with the sand blasting machine.
Copper wire or powder coating is done to avoid the risks of rust and oxidation from the surface of the component. Coating across the surface of the component also provides wear resistance.
Copper spray gun produces a thick layer of coating over the surface. coating with copper wire and powder is quite an expensive process.
In copper spray, metalizing rollers are used to deliver the coating wire. These rollers are a push and pull the wire in the copper spray gun. In copper spray gun for melting the copper wire both flame and electric arc process are used.
In the electric arc spray gun, process metal is melted or semi melts with the arc. The electric arc is generated between the anode and cathode for melting the wire or powder. In this type of spray gun to push and pull the wire compressed air and motor are used. When compressed air is used it is called air drive and when the motor is used to push and pull the wire it is called electric drive.
In copper spray metalizing if oxygen and gases are used it is called the copper flame spray gun. In this process, oxygen is used with acetylene and compressed air to melt the coating material. Copper provides a thick layer of coating on the component. Compressed air is used to atomized the coating material.
