Surface Treatments

There are many different methods of metal surface treatment. Metal surface treatment is a process where metal parts are prepared for painting. The preparation is commonly referred to as coatings pre-treatment. This usually involves creating a physical barrier that will protect metal against a corrosive environment.

The surface films used in chemical conversion coatings are formed by a means of a non-electrolytic chemical reaction that occurs between the metal surface and solution. They are adherent, inorganic crystalline or amorphous films. For the metal surface treatment to form a protective film, the base metal needs to be converted to one of the components that are less reactive to corrosion than the original metal surface.

Polishing

Polishing is the process of creating a smooth and shiny surface by rubbing the metal or using a chemical action, leaving a surface with a significant specular reflection.

Powder coating

Powder coating is a type of coating that is applied as a free-flowing, dry powder. The coating is typically applied electro statically and is then cured under heat to allow it to flow and form a “skin”.

Painting

Painting is a technique where a device sprays a coating (paint, ink, varnish, etc.) through the air onto a surface. Airbrushes are hand-held and used, instead of a brush,for detailed work such as…

Chrome Plating

Chrome plating is a technique of electroplating a thin layer of chromium onto a metal or plastic object.The chromed layer can be decorative,provide corrosion resistance…

E-coating

E-coating is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. It is ultimately caused by the presence of…

Anodizing

Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.
