Degreasing :
The first step in metal preparation should be the clean metal surface free from oil grease and corrosion product.
Alkaline cleaning solutions containing various wetting agents, detergents, emulsifiers together with inorganic and less frequently organic compounds. These bath may range from neutral to strongly alkaline with the alkalinity usually increase detergent effect.

Derusting Or Pickling:

During storage, transport, handling and fabrication a variety of soil and identification marks may be acquired where metal is stored for any length of time or under adverse storage condition in particular when it is stored out of doors corrosion products are developed on the metal surface.

Phosphating:

By far the most important industrial application of phosphate coatings is for the pre-treatment of steel and galvanized steel before painting. Almost all mass produce articles fabricated from sheet metal will be treated in this way. The role of the phosphate coating is providing a substrate eminently able for paint application can be considered from the following aspects.

• The provision of clean, uniform grease free surface.

• The promotion of adhesion of the organic film to the substrate by physical mechanism if the paint.

• The provision of a stable, insulating layer which inhabits the corrosion mechanism if the paint film is damaged.
