  2. 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.

  3. JTL-E .500 S&W Magnum 12-inch - Wikipedia

    en.wikipedia.org/wiki/JTL-E_.500_S&W_Magnum_12-inch

    The cold hammer forged barrel is made of a chrome-molybdenum-manganese steel. The revolver comes with a Nill grips, screwed together and magnetically secured with gold plated discs. It has a highly polished finish, a titanium nitride coating and a gold plating on the hammer and the trigger.

  4. Smith & Wesson Model 36 - Wikipedia

    en.wikipedia.org/wiki/Smith_&_Wesson_Model_36

    Approximately 615 Model 36-6 Target variations were produced. This variant had a 3-inch full lug barrel with adjustable sights and a blued glass finish. In 2002, Smith & Wesson reintroduced the Model 36 with gold features (hammer, thumbpiece, extractor, and trigger), calling it the "Model 36 Gold". The gold color was actually titanium nitride.

  5. Detonation spraying - Wikipedia

    en.wikipedia.org/wiki/Detonation_spraying

    These are powder flow rate, firing rate, distance from gun to target, how the D-gun is moved around to apply the coating, size of barrel, amount and composition of fuel and oxygen mixture. [citation needed] Detonation spraying is able to apply protective coatings to relatively sensitive and delicate materials.

  6. 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.

  7. Titanium aluminium nitride - Wikipedia

    en.wikipedia.org/wiki/Titanium_aluminium_nitride

    Aluminium titanium nitride (AlTiN) coated endmills using cathodic arc deposition technique. Titanium aluminium nitride (TiAlN) or aluminium titanium nitride (AlTiN; for aluminium contents higher than 50%) is a group of metastable hard coatings consisting of nitrogen and the metallic elements aluminium and titanium.

  8. Caliber (artillery) - Wikipedia

    en.wikipedia.org/wiki/Caliber_(artillery)

    The length of the barrel (especially for larger guns) is often quoted in multiples of the caliber, used, for example, in US naval rifles 3 in (76 mm) or larger. [2] The effective length of the barrel (from breech to muzzle) is divided by the barrel diameter to give a dimensionless quantity.

  9. Claridge Hi-Tec/Goncz Pistol - Wikipedia

    en.wikipedia.org/wiki/Claridge_Hi-Tec/Goncz_Pistol

    On the Goncz GA and Claridge T and L models, and all rifles, it also acts as a barrel shroud. The receiver tube houses the bolt, guide rods and guide springs. All Claridge Hi-Tec and Goncz Armament firearms utilize match barrels manufactured in-house that are button-rifled. The Goncz bolt structure is a clone of the SA-VZ23 submachine gun
