  2. Gold plating - Wikipedia

    en.wikipedia.org/wiki/Gold_plating

    A gold plated DMC DeLorean —one of five known examples to have been plated—on display at the National Automobile Museum in Reno, Nevada. Gold plating is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver (to make silver-gilt), by a chemical or electrochemical (electroplating) process.

  3. Electroless nickel immersion gold - Wikipedia

    en.wikipedia.org/wiki/Electroless_nickel...

    Electroless nickel immersion gold (ENIG or ENi/IAu), also known as immersion gold (Au), chemical Ni/Au or soft gold, is a metal plating process used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improve the solderability of copper contacts and plated through-holes. It consists of an electroless nickel plating ...

  4. 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 ...

  5. Electroplating - Wikipedia

    en.wikipedia.org/wiki/Electroplating

    Electroplating. Copper electroplating machine for layering PCBs. 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. The part to be coated acts as the cathode (negative ...

  6. Chrome plating - Wikipedia

    en.wikipedia.org/wiki/Chrome_plating

    Chrome plating. Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. A chrome plated part is called chrome, or is said to have been chromed. The chromium layer can be decorative, provide corrosion resistance, facilitate cleaning, and increase surface hardness.

  7. Metallizing - Wikipedia

    en.wikipedia.org/wiki/Metallizing

    Metallizing is the general name for the technique of coating metal on the surface of objects. Metallic coatings may be decorative, protective or functional. Techniques for metallization started as early as mirror making. In 1835, Justus von Liebig discovered the process of coating a glass surface with metallic silver, making the glass mirror ...

  8. Electroless deposition - Wikipedia

    en.wikipedia.org/wiki/Electroless_deposition

    Electroless deposition is advantageous in comparison to PVD, CVD, and electroplating deposition methods because it can be performed at ambient conditions. [2] [5] The plating method for Ni-P, Ni-Au, Ni-B, and Cu baths are distinct; however, the processes involve the same approach. The electroless deposition process is defined by four steps: [2 ...

  9. Electroless nickel-phosphorus plating - Wikipedia

    en.wikipedia.org/wiki/Electroless_nickel...

    Electroless nickel-phosphorus plating, also referred to as E-nickel, is a chemical process that deposits an even layer of nickel - phosphorus alloy on the surface of a solid substrate, like metal or plastic. The process involves dipping the substrate in a water solution containing nickel salt and a phosphorus-containing reducing agent, usually ...
