  2. Gilding - Wikipedia

    en.wikipedia.org/wiki/Gilding

    Gilded frame ready for burnishing with an agate stone tool Application of gold leaf to a reproduction of a 15th-century panel painting. Gilding is a decorative technique for applying a very thin coating of gold over solid surfaces such as metal (most common), wood, porcelain, or stone. [1] A gilded object is also described as "gilt".

  3. Fretting - Wikipedia

    en.wikipedia.org/wiki/Fretting

    Contact fretting can change the impedance of a B2B connector from milliohms to ohms in just minutes when vibration is present. The relatively soft and thin gold plating used on most high quality electrical connectors is quickly worn through exposing the underlying alloy metals and with fretting debris the impedance rapidly increases.

    en.wikipedia.org/wiki/Gold_plating

    Gold plated - gold layer thickness greater than or equal to 0.5 micron; Heavy gold plated / Vermeil - gold layer thickness greater than or equal to 2.5 micron; Gold plated silver jewellery can still tarnish as the silver atoms diffuse into the gold layer, causing slow gradual fading of its color and eventually causing tarnishing of the surface ...

  6. 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 ...

  7. Tinning - Wikipedia

    en.wikipedia.org/wiki/Tinning

    Hot tin-dipping is the process of immersing a part into a bath of pure molten tin at a temperature greater than 450 °F or 232 °C. Tinplate made via hot-dipped tin plating is made by cold rolling steel or iron, pickling to remove any scale, annealing to remove any strain hardening, and then coating it with a thin layer of tin.

    What is TDEE, and how can it help you get fit or lose weight? TDEE stands for total daily energy expenditure. Think of it as your overall metabolism — or how many calories you burn when resting ...

  9. Titanium nitride - Wikipedia

    en.wikipedia.org/wiki/Titanium_nitride

    Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
