other apps

1. Bonding the bottom layer to make the metal parts sprayed with the bottom layer, generally using sandblasting, electric drawing, molybdenum spraying, etc., after spraying, the solution and strength are not high. If the important parts are welded to the surface of the workpiece to be sprayed by the electric spark fusion machine, there is no oxide and dust impurities, which will increase the bonding strength between the spray coating and the substrate.

2. It is difficult to make aluminum components for soldering. It is very easy to solder a layer of copper on the surface of the aluminum device with an electric spark fusion machine.
