Advantages of Aluminizing and Spray Galvanizing compare to ordinary paint
1. Thermal spray coatings are widely used in preventing corrosion of many materials. A common application is the use of zinc to protect iron substrates. In this method, the surface of the metal is prepared by abrasive blast cleaning to ensure it is cleaned and roughened. Metal wire or powder is fed at a controlled rate into a flame or arc spraying process and the atomized metal impinges upon the surface being coated and becomes bonded to it. This process is easily adapted to production environments.

2. Good mechanical interlocking provided the abrasive grit blasting pretreatment is carried out correctly.

3. Thickness variable at will generally 100 - 150 microns but coatings of up to 500 microns can be applied.

4. The Aluminizing process is used to protect parts operating in high temperature environments against corrosion and oxidation. As a result, the most common parts coated are high temperature industrial chimney and muffler.

5. Coating with sealants that can provide a base for paints to give long life structures.

6. The ability to control the coating thickness and superior adhesion of the zinc to the iron substrate.
