  2. Electrometallurgy - Wikipedia

    en.wikipedia.org/wiki/Electrometallurgy

    Electrowinning, the extraction of metal from ores [2] Electrorefining, the purification of metals. [2] Metal powder production by electrodeposition is included in this category, or sometimes electrowinning, or a separate category depending on application. [2] Electroplating, the deposition of a layer of one metal on another [2]

  3. Electroplating - Wikipedia

    en.wikipedia.org/wiki/Electroplating

    As the science of electrochemistry grew, its relationship to electroplating became understood and other types of non-decorative metal electroplating were developed. Commercial electroplating of nickel, brass, tin, and zinc were developed by the 1850s. Electroplating baths and equipment based on the patents of the Elkingtons were scaled up to ...

  4. Copper electroplating - Wikipedia

    en.wikipedia.org/wiki/Copper_electroplating

    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]

  5. Chemical coloring of metals - Wikipedia

    en.wikipedia.org/wiki/Chemical_coloring_of_metals

    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 ...

  6. Metallurgy - Wikipedia

    en.wikipedia.org/wiki/Metallurgy

    A simplified diagram of electroplating copper on a metal. Electroplating is a chemical surface-treatment technique. It involves bonding a thin layer of another metal such as gold, silver, chromium or zinc to the surface of the product. This is done by selecting the coating material electrolyte solution, which is the material that is going to ...

  7. Electrochemical coloring of metals - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_coloring...

    Electrochemical coloring of metals is a process in which the surface color of metal is changed by electrochemical techniques, i.e. cathodic or anodic polarization. The first method of electrochemical coloring of metals are certainly Nobili's colored rings, discovered by Leopoldo Nobili , an Italian physicist in 1826.

  8. Nickel electroplating - Wikipedia

    en.wikipedia.org/wiki/Nickel_electroplating

    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]

  9. Science fair - Wikipedia

    en.wikipedia.org/wiki/Science_fair

    A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
