Като нитритирана вида на джепането от значение ли е? Това се опитвам да разбера да го е*а
Аз това съм чел, не само от оръжейни източници, а за процеса като цяло. Нитрирането НЕ Е ПОКРИТИЕ, както много хора се заблуждават.
Цитат:
Liquid Salt Bath Ferritic Nitrocarburizing Non-Cyanide Bath, commonly referred to as FNC or just plain nitriding. Salt Bath Nitriding/Nitrocarburizing is well known under various trade names, including ARCOR®, TENIFER®, TUFFTRIDE®, MELONITE®, and QPQ®.....
….The data shows FNC yields superior stainless steel barrel properties in terms of wear, with no negative effects on accuracy….
...Nitriding does not add a coating, rather, it changes the surface properties by diffusing nitrogen and carbon into the metal surface to yield an extremely smooth, uniform and wear-resistant bore....
….nitrided barrels did not leave any traces of copper while the plain stainless steel barrels needed extra cleaning to remove all jacket material.…
….The surface of a nitrided barrel is in the realm of 60 to 65 Rockwell. This surface layer becomes a very corrosion resistant “case” around the barrel steel....
….Benefits of a Nitrided Barrel....
The primary benefit of the nitriding process, from a rifle standpoint, is corrosion resistance. Barrels that undergo the process are extremely resilient in the face of corrosive environments, nearly four times more so than chrome.
Along with that is that the entire barrel, both inside and outside, undergo the same process. In effect, the entire barrel exterior becomes resistant. Chrome, on the other hand, only protects the bore of the barrel.
Additionally, the surface layer created by the nitriding process has a much lower coefficient of friction compared to bare metal or chrome. It’s not quite as relevant to barrel bores, but this means that you would need less lubrication on treated parts.
Cost is another benefit. Nitriding is both easier and cheaper to perform than chrome lining.....
Естествено, процесът си има и някои недостатъци.
*По-малка устойчивост на прегряване. Това повече би засегнало военното приложение, за нас едва ли би имало значение.
*При недобра технология на обработката, или последващо, а не фабрично нитриране, може да се получи откаляване на цевта.
Т.е., ако ползваш джепане, дето износва цевта, нитрираната е по-устойчива на износване и корозия.
