Isn’t titanium nitride a nitride coating? Lack of Reliable Magazines Limit Hornady’s 6mm ARC Cartridge Offerings, Flash Sale – 10% Off EOTech – Expires 6/16/20, Concerned About the Second Amendment? Subscribe to our email list and get exclusive access to promotions, sales events and more! This is by far the most popular and well-known finish to have on a bolt carrier group. Each barrel was placed in the salt chamber and after just 8 hours the Nitride finish barrel began to show signs of corrosion. Dimensional increase. It is used on HSS and carbide cutters. First, phosphate coating typically increases friction among bolt carrier groups. This chemical coating requires no need for electrochemical reactions, leading to a more uniform finish. This transformation gives treated steel some corrosion protection but requires frequent oiling to keep rust at bay. Phosphate is just basic parkerizing and will provide minimum corrosion resistance. No matter what conditions you put your firearm through, there is a finish out there that is ideal for your applications. Phosphate vs Nitride These are two of the least expensive finishes available. While Nickel Boron (NiB) is silver and shiny. Nitride is black and shiny. Mega has 416R stainless barrels that are nitride treated. It withstands impact effectively and passes 300-hour spray-on salt exposure tests, which exceed military standards. Treated surfaces are hard and very wear-resistant with a decent amount of lubricity. Whichever you choose, each will provide an insurance policy on your investment to keep that firearm as usable and valuable as it was the day you bought it. And easier to clean. It was slick and smooth. First off, I am an amateur shooter and just enjoy doing this sort of thing on the weekends. Every firearm in your arsenal is vulnerable, as even sitting idle in a gun safe will take its toll on your cold hard steel. In salt solution testing, it exceeded the 550-hour mark, which is well over minimal military standards. Only downside to nitride barrels are they do not break in over time, once you do you initial break in, the grouping you get is all your ever going to get until the barrel … Cold bluing changes color of steel to an attractive dark gray and is best used for small touch-ups or worn areas on a gun. You’ll probably never see a blued AR barrel, because the military specified a more robust finish, which is the de facto standard: Manganese phosphate, one of several treatments that fall under the umbrella name of “Parkerizing” (after the Parker Rust-Proof Phosphating Company). It can be applied to many different surfaces and is one of the toughest, most durable finishes marketed today. ... Chrome Lining vs. Salt Bath Nitriding: Which Barrel Finish Is Better? Phosphate is just fine, requires plenty of lube, but will last a long time. It is also known as Liquid/Salt Bath Ferritic Nitrocarburizing (FNC) process. It’s also porous and will make cleaning more difficult. Its corrosion resistance was proven by passing 500-hour salt exposure tests, so it’s a finish that handles just about anything. Cerakote, DuraCoat, and KG Gunkote are a few brand names on the spray-on gun coating list, but each differs in composition, and all cause a slight increase in dimensional thickness. Nitride: Nitride is used to harden the metal which vicariously increases the lifespan of the barrel. Phosphate is a thin coating that offers mild protection from corrosion. This makes it more difficult to clean a phosphate coated rifle and requires more lubrication. Instead of adding material to the bore (like Chrome lining), Nitride treats the existing steel by imbuing nitrogen into the steel itself. That being said, our nitride barrel life span for average use is 12,000 rounds. Bluing of steel is a traditional way to protect firearms from corrosion while at the same time reducing glare. And more exotic stuff like Titanium Nitride (TiN) is gold and pretty. But there is another kind of evil which we must fear most, and that is the indifference of good men. The nitriding process serves to enhance corrosion resistance on both the interior and exterior of the barrel. You should retry this using a 55gr cartridge instead. This finish is second only to diamonds in hardness. I know what you’re thinking. Manganese phosphate, the most commonly done at Anoplate, is often used on piston rings, cam shafts, gears and such as a protection against seizing of the surfaces and wear during the break-in periods. Phosphate. It is slightly more effective at corrosion resistance than bluing but requires frequent oiling to retain this attribute. Budget-conscious buyers who want something that works and can overlook some details like perfect finishing and dead-on accuracy Last but not least on the bluing list is rust or fume bluing. Nickel Boron usually costs more than Nitride and that money goes to more performance. The answer is … Colors can be customized to a certain extent, so it is a good choice for those who want a thin, durable finish paired with color. It also requires less lubricant to work well and is easier to clean. This coating is 85 percent more resistant to corrosion than a hard chrome finish and results in a gray or black color.
