Nu-Tride ® Salt Bath Nitriding Q.P.Q.™ This is accomplished by the ‘regenerator’ reacting chemically with and converting non-desirable carbonates (sludge) formed during normal bath chemical reactions back to cyanates. Liquid Nitriding Services Liquid Nitriding Services or nitriding in a molten salt bath employs the same temperature range as gas nitriding, which is 510 to 580°C liquid nitriding is a sub-critical casehardening process which increases surface hardness for a ferrous components. The service is used to improve the performance of a component that typical conventional surface engineering processes cannot meet, by improving mechanical properties of the part including corrosion resistance. Salt bath nitriding is thermochemical diffusion process where nitrogen-bearing salts generate controlled release of nitrogen at interface of ferrous part. The properties of the resulting nitrided or nitrocarburised surface are in many cases independent of the production process. One of the intrinsic properties of the epsilon iron nitride formed during salt bath nitriding is its relatively low coefficient of friction. The salt melt mainly consists of alkali cyanate and alkali carbonate. It is a thermochemical diffusion process whereby nitrogen-bearing salts generate a controlled release of nitrogen at … The high concentration of nitrogen chemically combines with iron and other nitride forming elements to produce an outer layer … On thinner material components improving the fatigue strength properties may allow for the engineer to design even lighter weight parts. During the process both nitrogen and carbon are liberated at the surface of the ferrous component. It remains a popular case hardening technique because it offers: In fact, nor is it the safer way. The life span of the product increases due to this process. If the hydraulic shaft is used in an outdoor application the enhanced corrosion protection can also be enjoyed. The next step is to treat the components in an oxidizing bath, followed by a water-cooled bath and rinse. The temperature used is typical of all nitrocarburizing processes: 550 to 570 °C.

Providing consistent high quality products and services to our customers at competitive prices, while being in strict compliance with all environmental, safety and health regulations. When steel parts are placed into a preheated liquid salt, there is sufficient energy localized near the surface due to differences in chemical potential that then allows nitrogen and carbon species to diffuse from the salt … 2021
Salt Bath Nitriding/Nitrocarburizing was originally created as an alternative to gas nitriding that would produce a more uniform case through surface contact between the substrate and liquid salt. Moreover the salts used also donate carbon to the work piece surface making salt bath a nitriding process. The life span of the product increases due to this process. By including the SBQIpolish/SBQ adjunct after SBN, surface lubricity is still greater than a chrome plated surface or a case hardened surface as determined both with and without lubrication, shown in Fig. Salts for nitrocarburizing How salt bath nitriding works.

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. A salt bath uses a liquid salt solution that is usually heated between 750 degrees Fahrenheit and 1050 degrees Fahrenheit. It is a thermochemical diffusion process where nitrogen, carbon, and to a very small degree, oxygen atoms diffuse into the surface of the steel part, forming a compound layer at the surface, and a diffusion layer. The product is then transferred to the MEL 1/TF1 tank containing the liquid Melonite salt to begin the Nitrocarburizing process. 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. Additionally, the Kolene … Liquid Nitriding Services or nitriding in a molten salt bath employs the same temperature range as gas nitriding, which is 510 to 580°C liquid nitriding is a sub-critical casehardening process which increases surface hardness for a ferrous components.
