SALT BATH NITRIDING OVERVIEW
Salt Bath Nitriding (SBN), also referred to as Liquid Nitriding and Ferritic Nitrocarburizing (FNC), is a specialized diffusion treatment that is used to cost effectively enhance resistance to wear, friction, corrosion, and fatigue on all ferrous materials, including cast irons, plain carbon steels, low alloys, and stainless steels.
SBN also maintains superior dimensional stability compared to other high-temperature treatments, while hardening a part’s surface up to greater than 70 Rockwell “C” (1075 HV). Unlike coatings or plating, Salt Bath Nitriding is a nearly zero-growth process that adds only a few microns, thereby maintaining extremely tight tolerances and allowing SBN to be the final step in the manufacturing process.
QPQ (Quench-Polish-Quench) is an adjunct to SBN, typically used when superior corrosion resistance is needed, and/or to enhance surface finish. QPQ begins with a standard SBN cycle, which produces a layer of iron nitride. The part is then mechanically polished and re-immersed into an oxidizing salt bath, followed by rinsing. QPQ optimizes corrosion protection, while leaving the original dimensions intact. In addition, the SBN/QPQ process results in an attractive black surface finish, ideal for applications where cosmetic appeal is especially important.
