I remember doing it in trade school about 100 years ago. Salt Bath Nitriding is performed at 560° - 570° C following necessary heat-treatment for core properties and finish machining. This is used as a supplemental addition to center the excessive salt drag-out during normal operation which tends to rapidly deplete the nitrate level below the recommended operating level of 5 % – 15 %. The heat requirements for liquid are lower than for the gas technique, and the hardened compound on the surface of the component is thicker. During the nitriding process, a combination of nitrogen and carbon is diffused into a metal surface using a high-temperature salt bath. It is a thermochemical diffusion process whereby nitrogen-bearing salts generate a controlled release of nitrogen at the interface of a ferrous part. 560° - 570° C. Nitriding Salt: Meproche N4 and Meproche N2; Nitriding Fluid: Meproche 5151; Nitro Carburizing Salt: Meproche N485; Carbonitriding Salt: Meproche N465; Oxidizing Salt: Meproche MT341; Nitrocarburizing Fluid: Meproche 5152 CN; Read more The salt bath nitriding equipment is fully hooded and ventilated. The Salt Bath Nitride process is a Thermo Chemical treatment that improves wear resistance and corrosion resistance of ferrous metals with little or no dimensional change. ISONITE® QPQ Nitriding. This permanently changes the molecular structure of the surface to provide a higher level of protection than plating or coating the material surface. We manufacture Nitriding, Nitro-carburizing Salts and Fluids used in Salt Bath Nitriding and Gas Nitriding. 6). Salt bath nitriding. The temperature used is typical of all … It is mandatory that the salt-bath chemistry is checked at the commencement of each shift and that the appropriate additions of salt are made to return the bath to its operational strength. Nu-Tride ® Salt Bath Nitriding Q.P.Q.™. Every quarter somebody would leave some oil in a hole and shoot molten salt out of the pot. It ensures dimensional stability of processed parts and core properties which remain unchanged, provided heat treatment temperatures were higher than the liquid nitriding temperature, i.e. Gas nitriding disperses gas to the metal via heat in a furnace or sealed atmosphere. Most have gone to Ion Nitriding for stainless or gas carburizing for mild steel. Handling systems range from simple manual hoists to fully automated, “recipe driven” systems. Accuracy of Criterion salt-bath nitrided barrels are on par with untreated match grade stainless-steel barrels. It contains carbonate compounds in addition to the alkaline nitrate and hydroxide … Liquid nitriding uses a cyanide salt mixture in a bath. The salts used also donate carbon to the workpiece surface making salt bath a nitrocarburizing process. Enhanced durability and corrosion resistance also serve to significantly increase overall effective barrel life. Salt-bath nitriding [3] can be an economical method providing that both the salt-bath chemistry and cleanliness are maintained (Fig. System layouts can vary from straight-line, “L”, “U” or “O” rail configurations depending on your requirements. Salt bath Nitriding/Nitrocarburizing is a process that is used to protect a metal surface and enhance its wear and corrosion resistance. It is also known as Liquid/Salt Bath Ferritic Nitrocarburizing (FNC) process. ‍ Delamin® ST [Oxidizing Bath Starter Salt] is a proprietary quench salt used only when starting a new quench bath. During MELONIZING® of the salt bath nitriding process, a nitro carburized layer is formed consisting of the outer compound layer (ε-iron nitride) and the diffusion layer thereunder. ISONITE® QPQ (per SAE AMS 2753) is a high-performance variety of salt bath nitrocarburizing process. We offer: Nu-Tride ® Salt Bath Nitriding (equivalent to Melonite ® process) Nu-Tride ® Salt Bath Nitriding Q.P.
