  2. Electrotyping - Wikipedia

    en.wikipedia.org/wiki/Electrotyping

    A slight problem with electrotyping of type is that the new form is slightly smaller than the original, and this deviance could accumulate if a letterform was repeatedly regenerated. Stephenson Blake's solution was to squash type slightly in a press or file it down to broaden it before putting it into the electrotype bath.

  3. Garfield Groundwater Contamination Superfund site - Wikipedia

    en.wikipedia.org/wiki/Garfield_Groundwater...

    The site was formally occupied by E.C Electroplating, an electroplating company that used chromic acid solution in their products. In 1983, a tank at the E.C Electroplating property malfunctioned and spilled chromic acid into the groundwater underneath the property that subsequently spread to the surrounding area.

  4. Electroplating - Wikipedia

    en.wikipedia.org/wiki/Electroplating

    Brush electroplating has several advantages over tank plating, including portability, the ability to plate items that for some reason cannot be tank plated (one application was the plating of portions of very large decorative support columns in a building restoration), low or no masking requirements, and comparatively low plating solution ...

  5. Electrogalvanization - Wikipedia

    en.wikipedia.org/wiki/Electrogalvanization

    Dedicated to plating at high speed in plants where the shortest plating time is critical (i.e. steel coil or pipe that runs at up to 200 m/min. The baths contain zinc sulfate and chloride to the maximum solubility level. Boric acid may be used as a pH buffer and to reduce the burning effect at high current densities.

  6. LIGA - Wikipedia

    en.wikipedia.org/wiki/LIGA

    LIGA consists of three main processing steps: lithography, electroplating, and molding. There are two main LIGA-fabrication technologies: X-Ray LIGA, which uses X-rays produced by a synchrotron to create high-aspect-ratio structures, and UV LIGA, a more accessible method which uses ultraviolet light to create structures with relatively low aspect ratios.

  7. Electrowinning - Wikipedia

    en.wikipedia.org/wiki/Electrowinning

    In electrowinning, an electrical current is passed from an inert anode through a leach solution containing the dissolved metal ions so that the metal is recovered as it is reduced and deposited in an electroplating process onto the cathode. In electrorefining, the anode consists of the impure metal (e.g., copper) to be refined. The impure ...

  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. Copper electroplating - Wikipedia

    en.wikipedia.org/wiki/Copper_electroplating

    Excluding the continuous strip plating industry, copper is the second most commonly-plated metal after nickel. [6] Copper electroplating offers a number of advantages over other plating processes, including low metal cost, high-conductivity and high-ductility bright finish, and high plating efficiency.
