Plasma nitriding is a method of thermochemical treatment, which is widely used to enhance surface hardness, fatigue strength, and corrosion resistance of steels The process Nitriding is a diffusion process and not a deposition process. There are two general types of nitriding processes: 1. Salt bath Nitriding/Nitrocarburizing is a process that is used to protect a metal surface and enhance its wear and corrosion resistance. At Nitriding Ltd, we perform Ion-Plasma Nitriding for some of the most critical commercial applications on earth - and for some of the most demanding customers. Nitriding is a case-hardening process of enriching the solid steel surface with nitrogen at a low temperature, normally in the range of 500-575°C (i.e., below A 1), when the steel is ferritic. It will act as a solid-lubricating film that can reduce the friction coefficient and the adhesive wear of the materials. Nitriding-Sulfurizing Process In addition to the advantages of the normal nitriding process, the parts will also have a layer of ferric sulfide at the surface in this case. It occurs around 510°C. Gas-Nitriding 2. It is a diffusion procedure that is reliant on a nitrogen source, and a low thermal process temperature (which, by looking at the Iron Carbon Equilibrium diagram is in the ferrite/cementite region of that diagram) just as the process of carburizing and carbo-nitriding processes are. Fluidised bed/salt bath nitriding/nitrocarburising is a process used to improve the wear resistance, fatigue strength and, when combined with post oxidation through oxidative cooling, improved corrosion resistance on products made from steel, cast iron and sintered iron. Nitriding is done in gas at about 510 o C (950 o F). Nitriding Experts is a group of specialists with more than 20 years of experience in the field of nitriding - as nitriding service providers, process developers and as manufacturers of Plasma Nitriding Units.We closely cooperate with nitriding service companies and turn key plant manufacturers at home and abroad. Nitriding. Heat Treatment -The Science of Forging (feat. The process temperature for Gas Nitriding … Nitriding is usually done by heating steel objects in gaseous ammonia (NH3) at temperatures between 500 and 550 This process takes place at relatively low temperatures (700F-1200F), which results in nitrogen diffusion into the base material. A significant increase in a gear’s performance can be realized by using modern nitriding techniques. DNS team members have a wealth of experience in salt bath nitriding and understand the importance of starting your nitriding process with high quality salts. Gas Nitriding Heat Treatment for Case-Hardened Machined Parts, Stampings, Tools & Wear Components. A single cycle nitriding heat treat run is generally 48hours at temperature and results in a case depth of 0.015 – 0.020″. During plasma nitriding, nitrogen capable of diffusion is supplied from the plasma to the surface; in gas nitriding, this is from ammonia gas. Nitriding Ltd In addition, two delivery trucks and our team of radio-dispatched drivers provide you with free, daily pick-up and delivery service area aroud city of Plovdiv. Case-hardening is a simple process of hardening the surface of a metal object. Disassociated Ammonia is the source of atomic Nitrogen that is diffused into the part surface to create a hardened case that is wear resistant and corrosion resistant. This alloy can be age hardened to very high strengths while providing very high surface hardness through nitriding. With our team’s particular experience in metal surface treatment, specifically for customers in the automotive sector, we are in the unique position as salt suppliers to understand your need for lot traceability and salt quality assurance.

The process of nitriding is one of the most promising of the verity of many thermochemical methods known to the gear industry. Plasma ion nitriding is a process where ammonia gas is introduced into a furnace. Gas-Nitriding: Gas nitriding is the most commonly used nitriding method. This grade is vacuum remelted (VAR) to improve microcleanliness giving the alloy improved fatigue strength. Nitriding is a case-hardening process in which nitrogen is introduced into the surface of a ferrous alloy such as steel by holding the metal at a temperature below that at which the crystal structure begins to transform to austenite on heating (Ac 1) as defined by the Iron-Carbon Phase Diagram (Fig. It is often used as gears in the rotorcraft industry. Plasma nitriding offers the following advantages over gas nitriding: No harmful ingredients like ammonia are used; only non-toxic gases contained in the air. Nitriding and nitrocarburising are low temperature, low distortion "thermochemical" heat treatments carried out to enhance the surface properties of finished or near finished ferrous components. The entire nitriding process is executed in an automatic, self-adjusting and operator independent manner. Nitriding diffuses nitrogen into the surface of certain metals creating a hard surface more resistant to wear and corrosion.
