2013年9月23日 · The Melonite (Salt Bath Nitride/SBN) is a treatment, not a plating. It does not shrink or enlarge the bore at all. My only concern is that a Melonite barrel should be very very precisely cut using the sharpest possible carbide tools as to …

2016年11月17日 · QPQ (quench/polish/quench) is melonite polish melonite so it does look different when finished due to the polishing, like a polished and blued 1911 vs just a blued 1911. ETA: Supposedly BMW uses the Tennifer process on its cam shafts and a few other heavy wear parts, Gaston Glock discovered this and that what lead him to treating his slides ...

2008年8月4日 · Re: Melonite treatment for bolt action rifles The effect on the barrel is a function of temperature + time. Your barrel mfg should know the phase diagram for the specific alloy being used, and be able to tell you exactly what happens to …

2013年5月15日 · Here is a quote from a Nitrocarburizing (Nitride/melonite) processer: Melonite QPQ Process The Melonite QPQ process is a multi step process that provides a very uniform consistent nitride layer on your components. The first step of the process is a preheat to raise the components surface temperature to about 700 - 800°F in air.

2016年2月8日 · Melonite™ and Melonite QPQ™ are thermochemical processes intended for the case hardening of iron based metals. These processes are categorized as molten salt bath ferritic nitrocarburizing. During these processes, nitrogen, carbon, and small amounts of oxygen are diffused into the surface of the steel, creating an epsilon iron nitride layer ...

2014年12月3日 · Personally running a Glock G22 (40 S&W chamber) for about 25 years with NO lube or oil on the outside of the slide, and living on the shore of the Gulf of Mexico in an area that also sees a lot of rainfall, and seeing NO rust whatsover, and not seeing any on the slides of other Glocks, I'd say that it would be extremely difficult (although not impossible) to get surface corrosoin on a melonite ...

2012年11月29日 · Re: Melonite or Cerakote?? The melonite process shouldn't cause any issues. If it did, they wouldn't melonite anything that sees stress. Personally I would skip both, give Birdsong a call and Black-T everything. I have a pre-Springfield XD9 (HS2000) and they didn't melonite, just used a bluing finish and I had a rust issue.

2011年8月9日 · The companies that do Nitriding/Melonite do run test on sample parts to ensure that the process is doing what it is suppose to. Im glad to hear that people enjoy the process and i would like to know the results of processed barrel once you get a chance to put it to the challenge, i have heard some very good things about the process.

2010年12月10日 · The 284 had 48 rounds fired prior to melonite. The 708 had ~100, the CBI 308 ~200 and the savage takeoff was unknown, though I was told it was about 200. The 284 never printed a good group prior to, or after melonite. It was later sent back to bartlein and replaced (thank you Bartlein). The 7-08 shot pretty nice prior to melonite.

2015年9月8日 · Quoted: Found a great deal on a 16" carb length barrel, my only concern is its parkerized. I've been mainly looking at melonite or possible chrome lined barrels but I havent heard or read too much about parkerized.
