Surface Preparation – Since the bond between the base metal and the deposited metal is purely mechanical, it is essential that the surface of the base metal should be prepared properly so that a good mechanical interlocking between the sprayed metal and base metal can be obtained. The first step in surface preparation is to clean the base metal surface of all foreign substances such as Rust, Corrosion, Oxides, Oil, Grease, Paints,Etc.
