Anodiser is a metal oxide finish as opposed to paint. An anodised finish is formed by an electrolytic process in which the object to be coated serves as the anode, hence the term anodised. Anodising produces a durable semi-translucent finish in a wide range of colors with black and gold being common in audio equipment. It is also very useful and important for many purposes.
Anodized metal has been brought through an electrochemical process which changes the molecular structure of the surface layer, giving it a thin, protective film. In the anodisation process, the metal is placed in an acid bath and an electrical current is passed through the tank. This process causes a controlled oxidation of the metal's surface to occur. Aluminum is often anodised, as is magnesium, titanium, and tantalum. Anodised metal has a lustrous sheen; the anodising process can produce colorful surfaces.
Anodiser checks surface roughness with in-process laser technology Productivity is improved when anodised plates can be checked for surface quality without interrupting production.
Anodiser Controls anodizing equipment to provide corrosion resistant surface to aluminum objects: selects holding rack according to size, shape, and number of objects to be anodised. Wires or clips objects to anodising rack and immerses rack in series of cleaning, etching, and rinsing baths. Positions objects in anodising tank by suspending them from anode. Estimates amount of electric current and time required to anodise material that turns rheostat to regulate flow of current. Removes objects from tank after specified time, rinses objects, and immerses them in bath of hot water or dichromate solution to seal oxide coating. Hangs objects on racks to air-dry. May immerse objects in dye bath to color them for decorative or identification purposes. May anodise work piece with corrosion resistant material, using automated equipment that automatically cleans, rinses, and coats.
