  2. Rhodium - Wikipedia

    en.wikipedia.org/wiki/Rhodium

    Rhodium is a hard, silvery, durable metal that has a high reflectance. Rhodium metal does not normally form an oxide, even when heated. [25] Oxygen is absorbed from the atmosphere only at the melting point of rhodium, but is released on solidification. [26] Rhodium has both a higher melting point and lower density than platinum.

  3. Plating - Wikipedia

    en.wikipedia.org/wiki/Plating

    Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...

  4. Centrifugal casting (silversmithing) - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_casting...

    Centrifugal casting, or centrifuging, [1] is used as a means of casting small, detailed parts or jewelry. [2] An articulated arm is free to spin around a vertical axle, which is driven by an electric motor or a spring. The entire mechanism is enclosed in a tub or drum to contain hot metal should the mold break or an excess of metal be used.

    Molten metal before casting Casting iron in a sand mold. In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape.

  6. Coinage metals - Wikipedia

    en.wikipedia.org/wiki/Coinage_metals

    Plating, cladding or other coating methods are used to form an outer layer of metal and are typically used to replace a more expensive metal while retaining the former appearance. For example, United States cents since 1982 are zinc with copper-plating, and thus retain their prior copper look while having a less expensive composition. [ 8 ]

  7. Electroplating - Wikipedia

    en.wikipedia.org/wiki/Electroplating

    The plating industry received a big boost with the advent of the development of electric generators in the late 19th century. With the higher currents available, metal machine components, hardware, and automotive parts requiring corrosion protection and enhanced wear properties, along with better appearance, could be processed in bulk.

  8. Rhodium-platinum oxide - Wikipedia

    en.wikipedia.org/wiki/Rhodium-platinum_oxide

    Rhodium-platinum oxide (Rh–Pt oxide), or Nishimura's catalyst, is an inorganic compound used as a hydrogenation catalyst. [2] Uses. Rh–Pt oxide is used to reduce ...

  9. Jewellery - Wikipedia

    en.wikipedia.org/wiki/Jewellery

    Some jewellery is plated to give it a shiny, reflective look or to achieve a desired colour. Sterling silver jewellery may be plated with a thin layer of 0.999 fine silver (a process known as flashing) or plated with rhodium or gold. Base metal costume jewellery may also be plated with silver, gold, or rhodium for a more attractive finish.
