Once aluminum metal is exposed to air, it will immediately combine with oxygen in the air to form aluminum oxide, an inert protective layer. In nature, this oxide deposit is only one millionth of an inch deep. Aluminum anodizing is a well known method of thickening the aluminum oxide coating to provide greater protection. It is a restricted oxidation of the surface achieved by immersion in an electrolyte (it will generally be dilute sulfuric acid). Production of anodized aluminum coatings: In the process, the metal is used as the anode and then a very low voltage, high amperage direct current is passed through the metal. A rigid and inert oxide film initially forms on the surface and is followed by a less dense oxide layer in which there are capillary pores. These capillary pores allow oxidation to continue. Unlike paint and plating which are coatings that are added to the lower metal, anodic coatings develop downward on the parent metal and form an integral part of the metal itself.
IL Chemical for metal plating is also known as selective plating, brush plating, swab plating, or shrink plating. The plating tool consists of an insulated handle into which an anode is molded, usually from graphite. It requires a lower initial cost, easy to operate and reduces waste disposal. Brush plating is an important part of the manufacturing process in many industries. IL metal plating chemicals can be used due to their flexibility and versatility. It can be used in the workshop or in the field. It can be brought to the job site for operations such as crankshaft bearing diameters and resizing of worn stamping equipment. Brush plating saves time and money. Shipping cost is eliminated on metal plating. Requires minimal masking. Flame spraying and welding operations require a lot of heat which can twist the part. Metal plating does not require a lot of heat. It is very portable.
