ผมว่าโดยรวมแล้วก็ยังเป็นกระบวนการ nitrocarburizing เหมือนเดิม แค่เปลี่ยนวิธีในการเกิดปฏิกริยาเท่านั้นครับ
Despite the naming the process is a modified form of nitriding and not carburizing. The shared attributes of this class of this process is the introduction of nitrogen and carbon in the ferritic state of the material. The processes are broken up into four main cl.: gaseous, salt bath, ion or plasma, or fluidized-bed. The trade name and patented processes may vary slightly from the general description, but they are all a form of ferritic nitrocarburizing.[7]
Glock Ges.m.b.H., an Austrian firearms manufacturer, utilizes the Tenifer process 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. The final matte, non-glare finish meets or exceeds stainless steel specifications, is 85% more corrosion resistant than a hard chrome finish, and is 99.9% salt-water corrosion resistant. After the Tenifer process, a black Parkerized finish is applied and the slide is protected even if the finish were to wear off. Besides Glock several other pistol manufacturers like Smith & Wesson and Springfield Armory, Inc. also use ferritic nitrocarburizing for finishing parts like barrels and slides but they call it Melonite finish. Pistol manufacturer Caracal International L.L.C. uses ferritic nitrocarburizing for finishing parts like barrels and slides with the plasma-based Plasox process.
