  2. Quench polish quench - Wikipedia

    en.wikipedia.org/wiki/Quench_polish_quench

    The process starts with a standard salt bath nitrocarburizing cycle, which produces a layer of ε iron nitride. [4] Next, the workpiece is mechanically polished; typical polishing processes include vibratory finishing, lapping, and centerless grinding. Finally, the workpiece is re-immersed into the salt quench bath for 20 to 30 minutes, rinsed ...

  3. 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.

  4. Nitriding - Wikipedia

    en.wikipedia.org/wiki/Nitriding

    Nitriding alloys are alloy steels with nitride-forming elements such as aluminum, chromium, molybdenum and titanium. In 2015, nitriding was used to generate a unique duplex microstructure in an iron-manganese alloy ( martensite - austenite , austenite - ferrite ), known to be associated with strongly enhanced mechanical properties.

  5. Titanium aluminium nitride - Wikipedia

    en.wikipedia.org/wiki/Titanium_aluminium_nitride

    The coatings are mostly deposited by cathodic arc deposition or magnetron sputtering. Even though most TiAlN and AlTiN coatings are industrially synthesized using alloy targets with specific percentages of aluminium and titanium it is possible to produce TiAlN coatings with pure Al and Ti targets using a cathodic arc deposition technique.

  6. Metalworking - Wikipedia

    en.wikipedia.org/wiki/Metalworking

    A file is an abrasive surface like this one that allows machinists to remove small, imprecise amounts of metal. Filing is combination of grinding and saw tooth cutting using a file . Prior to the development of modern machining equipment it provided a relatively accurate means for the production of small parts, especially those with flat surfaces.

  7. Ferritic nitrocarburizing - Wikipedia

    en.wikipedia.org/wiki/Ferritic_nitrocarburizing

    Glock Ges.m.b.H., an Austrian firearms manufacturer, utilized the Tenifer process until 2010, to protect the barrels and slides of the pistols they manufacture. The finish on a Glock pistol is the third and final hardening process. It is 0.05 mm (0.0020 in) thick and produces a 64 Rockwell C hardness rating via a 500 °C (932 °F) nitride bath ...

  8. Sputter deposition - Wikipedia

    en.wikipedia.org/wiki/Sputter_deposition

    Sputter coating in scanning electron microscopy is a sputter deposition process [clarification needed] to cover a specimen with a thin layer of conducting material, typically a metal, such as a gold/palladium (Au/Pd) alloy. A conductive coating is needed to prevent charging of a specimen with an electron beam in conventional SEM mode (high ...

  9. Drill bit - Wikipedia

    en.wikipedia.org/wiki/Drill_bit

    A black oxide coating provides heat resistance and lubricity, as well as corrosion resistance. The coating increases the life of high-speed steel bits. Titanium nitride (TiN) is a very hard metallic material that can be used to coat a high-speed steel bit (usually a twist bit), extending the cutting life by three or more times. Even after ...
