The product is then transferred to the MEL 1/TF1 tank containing the liquid Melonite salt to begin the Nitrocarburizing process. Melonite occurs as trigonal crystals, which cleave in a (0001) direction. References. Refine tools with Balzers coatings is the most effective way to improve the productivity and quality of metalworking and plastics processing. Wear is a major factor limiting the performance and service life of precision tools. Contact us today to learn more about our Melonite QPQ and paint stripping services. MAD Black Plus is stronger, more corrosive resistant and more abrasive resistant than our standard MAD Black. It is a thermochemical diffusion process whereby nitrogen-bearing salts generate a controlled release of nitrogen at the interface of a ferrous part. I found info for one guy on the site but it was dated quite a … However, nitride is preferred to phosphate coating for a few important reasons. Both diffuse nitrogen and carbon In recent years, the firearms field has seen the introduction of revolutionary new metal coatings and surface treatments that deliver unprecedented levels of corrosion protection, wear resistance and reliability. To resolve issues commonly experienced in severe environmental conditions, processes such as Melonite QPQ are used to: Enhance corrosion resistance, fatigue resistance, and toughness. barrel to withstand up to four times the amount of corrosion as chrome or It is most commonly used on steels, sintered irons, and cast irons to lower friction and improve wear and corrosion resistance. The first step of the process is a preheat to raise the components surface temperature to about 700 - 800°F in air. When Coating can be duplexed with sublayers or topcoats to enhance specific properties customers may desire. Processes for stainless steels, alloy steels & tool steels. Hardcut™ Crosscut™ Maximizer. Location doesn't really matter as long as it's in the continental U.S. Coating Selection. we’re a premier barrel nitriding service provider. from this premier service. The salt … Whether you’re you can expect another barrel nitriding service to offer similar benefits and Melonite is a patented thermochemical treatment used for It is also known as Liquid/Salt Bath Ferritic Nitrocarburizing (FNC) process. Manganese Phosphate. Corrosion resistance of unalloyed and low alloyed steels is greatly improved. I am often involved in arguments regarding the these two finishes on Smith & Wesson and Walther forums. The bolt carrier and gas key are chromed, and the barrel sports their Melonite coating. Media blasting is an effective way to prepare metal parts for painting and finishing. While these traditional surface finishing processes were used in many industries for many years, they are each being methodically replaced by a superior finishing process – Melonite ® . ISO 9001:2015, AS 9100 Rev.D certified Melonite is a corrosive preventative treatment and is less prone to rust than stainless steel. Learn more about our Melonite® coating, media blasting and paint stripping services below or contact us to discuss your metal finishing project. Custom gunsmithing, milling services, custom assembled products, finishes and engraving are all performed AFTER your order is placed with us. resistance on all surfaces of your rifle barrel. Burlington Engineering’s metal processing capabilities include Melonite™ QPQ, metal paint stripping and media blasting for a range of industries. Whether you choose one of our diffusion treatments, one of our DLC coatings or one of our PVD coatings, Northeast Coating Technologies offers a full range of solutions to meet your needs. Metal components used in mining, oil and gas, marine and other applications are subjected to harsh conditions that can accelerate corrosion and surface wear. The process uses a salt bath of alkali cyanate. At PPG Coatings Services, we value those traits because our industry is constantly changing. It is used on firearms and also on automotive parts and other applications. During the process, which takes place between 900F and 1075F, the metal surface is enriched with nitrogen and carbon. They’ve fed two M&P15 Sport test rifles a combined ~170,000 rounds of various brands of ammunition without any [visible] damage to the Melonite finishing process. MAD Custom Coating remains on the cutting edge of technology for protective and functional finishes. be applied to both the barrel and bolt carrier group for rugged rifle Automotive & Transportation. The process is Opportunity. resistance during normal use. capabilities as patented Melonite servicing. an investment than a phosphate coating, this barrel service is more Pre- and post-treatments. carbon steel, stainless and austenitic steel, alloy steel, tool and die steels Melonite ® processing produces a hardened, corrosion-resistant surface that will out-perform metal plating (hard chrome, zinc, or nickel), gas nitriding, Parkerizing ®, and black oxide or bluing. I am just looking to build a spare rifle, nothing fancy. Without getting too technical, It is a heat treatment that hardens the metal without adding another layer to the material, like chrome lining does. Optimizer™ Plus. It also does not require any oil to operate! either salt bath or nitrocarburizing options. Burlington Engineering, Inc. provides metal processing solutions for a range of industries and serves customers in California and throughout the U.S. We constantly invest in our business, but we also invest in you, providing the skills, technical knowledge and independence you need to create loyal, satisfied and successful customers. Multi Purpose. Getting one in stainless will make easy to tell one from the other. While nitriding may be more of © 2021 Burlington Engineering, Inc. All Rights Reserved. Work with Specialty Steel Treating today to discover why The process is very similar to barrel nitriding but uses a patented chemical solution for either salt bath or nitrocarburizing options. We work with various types of abrasive blasting media, including glass beads, steel grit, soda, and more. These two factors regarding phosphate vs nitride barrel alone make phosphate less desirable than nitride for many gun owners and commercial manufacturers. Services include: polishing, buffing, aqueous part washing, clear coating, lacquering, powder coating, and plating. It is used to improve the wear resistance, the fatigue strength, and corrosion resistance of components made from steel, cast iron, and sintered iron materials. Melonite is not a coating, will not wear away, and provides a higher level of protection than hard chrome, nickel, and similar metal plating methods. Typically, this process involves either a salt bath nitriding For over 60 years Specialty Steel Treating has been a premier provider of heat treating services for a range of applications. While some features and specifications may vary slightly, During these processes, nitrogen, carbon, and small amounts of oxygen are diffused into the surface of the steel, creating an epsilon iron nitride layer (ε - Fe x N). Automotive & Transportation . A salt bath uses a liquid salt solution that is usually While there are many options for case hardening rifle barrels, nitriding offers Craftguard celebrated its "50th Anniversary" in 2014. Q. A discussion started in 2004 but continuing through 2018 --> 2004. Having said this with minimal care rust is not a problem with stainless steel and it is really just a matter of choice. This includes dehorning, bead blasting and polishing when applicable. Ensure you choose a quality barrel While our standard MAD Black finish is still amazing, we’ve made it better. interior and exterior of your rifle barrel. Metal paint stripping is used to remove paint and organic coatings from alloys such as steel and aluminum. The MELONITE process also begins with the placement of parts in a re-circulating air preheat furnace, followed by immersion for 60-240 minutes in a molten nitrogen-rich MELONITE specific salt solution contained in an aerated furnace. Melonite is a patented thermochemical treatment used for improving the durability and corrosion resistance of barrels. Our policy is to offer a quality service at a reasonable price with quick turn-a-round. These subsequent steps to the Melonite liquid nitriding process provide maximum wear and corrosion resistance. Smith claims that the bare bones approach has no effect on durability. nitriding and polishing creates a black coating that is resistant to corrosion Find out how this service Melonite QPQ Process The Melonite QPQ process is a multi step process that provides a very uniform consistent nitride layer on your components.
