Anodizing
Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.. The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell.Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint …

Electron
The electron ( e − or β −) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron's mass is approximately 1/1836 that of the …

Nickel Electroplating | Products Finishing
Copper, lead, zinc, cadmium and some organics can be removed by low current density electrolysis. The most efficient current density may vary to some degree for each metal, but 2-5 asf of cathode surface can be tried first. Corrugated iron is ideal for cathodes, since it will provide a favorable distribution of current density.
