That is, the electroplating processes applied to the component parts were taxed, and then the same processes were re-taxed in the sale of the final product. In July, Erie Plating Company filed a petition for reassessment, a hearing was held in January of the following year, and three months later the Bureau reaffirmed its assessments.
Anodizing changes the microscopic texture of the surface and the crystal structure of the metal near the surface. Thick coatings are normally porous, so a sealing process is often needed to achieve corrosion resistance. Anodized aluminium surfaces, for example, are harder than aluminium but have low to moderate wear resistance that can be ...
Type 1 photosensitive anodized aluminum is anodized aluminum that has been impregnated with a silver compound which, when exposed to a light source, creates an activated latent image. [5] Upon development [ 6 ] and fixing [ 7 ] a black, silver-based image is formed inside of the metal.
Top-view scanning electron microscopy image of AAO . Anodic aluminum oxide, anodic aluminum oxide (AAO), or anodic alumina is a self-organized form of aluminum oxide that has a honeycomb-like structure formed by high density arrays of uniform and parallel pores.
Anodic protection (AP) otherwise referred to as Anodic Control is a technique to control the corrosion of a metal surface by making it the anode of an electrochemical cell and controlling the electrode potential in a zone where the metal is passive.
Electrogalvanizing is a process in which a layer of zinc is bonded to steel to protect against corrosion, enhance adhesion, or give an aesthetic appeal.The process involves electroplating, running a current of electricity through a saline-/zinc-based electrolytic solution with a zinc anode and steel cathode.

Aluminium foil (or aluminum foil in American English; occasionally called tin foil) is aluminium prepared in thin metal leaves. The foil is pliable and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful.
