Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current.
Copper plating on aluminium. Copper electroplating is the process of electroplating a layer of copper onto the surface of a metal object. Copper is used both as a standalone coating and as an undercoat onto which other metals are subsequently plated. [1]
Nickel electroplating is a process of depositing nickel onto a metal part. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. [3] To clean and protect the part during the plating process, a combination of heat treating, cleaning, masking, pickling, and etching may be used. [1]
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.
Trivalent chromium plating is an alternative to hexavalent chromium in certain applications and thicknesses (e.g. decorative plating). [2] A trivalent chromium plating process is similar to the hexavalent chromium plating process, except for the bath chemistry and anode composition.
We also know that George Richards Elkington (1801–1865), otherwise known for his patent for galvanic gilding and silver plating from 1840 patented at least one process of electrochemical coloring of metals (the American J.E .Stareck developed ten variants of his process around 1937). [10]
To really bring it over the top, Ina calls for simmering a small mixture of butter and flour just before plating. It'll help the gravy thicken to the perfect consistency. Serve, and expect plenty ...
Chemical coloring of metals is the process of changing the color of metal surfaces with different chemical solutions. The chemical coloring of metals can be split into three types: electroplating – coating the metal surface with another metal using electrolysis. patination – chemically reacting the metal surface to form a colored oxide or ...
