Hard chrome plating. Hard chrome, also known as industrial chrome or engineered chrome, is used to reduce friction, improve durability through abrasion tolerance and wear resistance in general, minimize galling or seizing of parts, expand chemical inertness to include a broader set of conditions (such as oxidation resistance), and bulking ...
The CN08 is the main armament of the K2 Black Panther, and the gun barrel is applied with internal chrome plating technology for the large-caliber gun. The gun barrel can endure a high explosive force as a result of the increased stiffness and wear resistance provided by this internal chromium surface.
Mid-20th century rifles such as the American M14 and the Russian SKS, fitted with polished wood stocks, chrome plating and other decorative finishes, are common ceremonial weapons for honor guard units. Another example is the use of a firearm to signal the start of a race. Guns are also used in celebratory gunfire.
The Semmerling series of pistols included the LM1, LM2 (.380 ACP semi-automatic variant), LM3 and the XLM (.45 ACP semi-automatic variant) and LM4. [2] The only version available to the public was the LM4, which was first designed and manufactured in the US in the early 1980s and marketed at a price of US$645.
In 1975 an updated version of the gun, the T254E3 was designed, focusing on the use of chrome plating to improve accuracy. It was used to evaluate improvements to the gun's performance using discarding sabot ammunition. Two guns were built and underwent firing trials at Aberdeen [16] and technical evaluations at the Watervliet Arsenal. [17]
The shotgun has single column detachable box magazine and smoothbore barrel with chrome plating. [2] [1] The bolt has two lugs.[10]All shotguns equipped with safety mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling.
In place of the earlier chrome plating, blued finish was used on the bolt, trigger, and cocking piece starting in October 1944. The firing pin design was changed in January 1946. Sources: Houze 1993, p. 160 & Henshaw 1993, pp. 104–105. Approximately 383,597 [2] to 652,538 [3] Model 67s had been produced when production ceased in 1963. [8]
Enhanced main gun : New rifling and chrome plating will increase barrel life from 1,000 rounds to 1,500 rounds (with maximum charges), longer range, and allow faster firing rate. High-response artillery automation system : Key feature of the A2 and future A3 upgrade.
