| Anodizing: Metal Coatings and Finishing |
Anodizing is an electrical/chemical process in which a metal, such as aluminum is altered to produce a tough oxide layer on its surface. This oxide layer protects the underlying metal against corrosion and abrasion, extending the life of the metal. There are many uses and values for this type of coating.
Extending the life span of a structure is cost effective and profitable. Anodized surfaces will hold up better under harsh weather conditions as well as under heat and friction. Anodizing can also be a cosmetic choice. Color can be introduced into the process to dye the surface of the metal. This gives a polished or matte look to the construction. Because anodizing in not a painting procedure, there is no fear of increasing the surface of the metal, so tight fitting parts will still connect correctly.
This process is relatively safe but because you will be using acids and other corrosive chemicals it is important that you have protective gear on at all times. Goggles and gloves will need to be worn while anodizing parts. Make sure you observe all safety rules with chemicals and keep them out of reach of children.
