Metallizing 
Metallization is a technique that has been around for a long time but owing to changes in opinions in the field of corrosion resistance, this technique is increasingly being used. Logical, because a properly applied metallizing layer can provide up to 50 years of protection against corrosion. A metallization layer is always applied to a blank blasted substrate. Various metals or alloys can be used for the metallization. Materials that are used a lot are zinc (zinc metal spraying), an alloy of zinc-aluminium or aluminium-magnesium (Thermal Spray Aluminium or TSA). These materials are supplied in wire form. Using an electric arc, the wire is melted, after which this is blasted on to the surface with compressed air. The metal particles hit the surface where they cool down almost instantly and adhere to the substrate.
