This process is a thermochemical treatment that involves diffusional addition ofnitrogen and carbon. This process is generally done at temperatures below 580 C(1076 F) and usually for 3 hours. It is also called short nitriding process . Theessential difference between nitriding and nitrocarburising is that in nitrocarburising, the surface compound layer contributes for improved properties whilethe diffused nitrogen layer is important in nitriding process. All ferrous alloys can beferritic nitro carburised while only nitrodable steels containing Al, Cr, Mo can be usedfor nitriding process. The process is done in an atmosphere containing NH3 and acarbon donor such as LP gas, CO2 or Propane at temperatures below 580 C(1076 F). The ferrous material after nitrocarburising need not be quenched ifsurface hardness is the only consideration. However if the steel after the process isquenched in oil or water, nitrogen is retained in solution in the diffusion zone whichcontribute for improved fatigue life.Hardness after Ferritic Nitrocarburising of few ferrous alloys is as follows.

Service Description: Keeping in pace with the development in the industry, Metal Treat has acquired a state-of-the art facility for rendering the services of Plasma Nitriding, involving considerable capital expenditure in the year 1999 and are now offering Plasma Nitriding services to various OEM across length and breadth of country. Plasma Nitriding works by placing the component to be treated in a vacuum furnace so that it is electrically insulated from the furnace.The vacuum employed is relatively low, and normally, the DC voltage does not drop in a linear way. Almost the entire applied voltage drops directly in front of the cathode , producing the typical luminous purple glow seam in the cathode fall region around the component outline. The glow seam follows every contour of the component so that all surfaces receive uniform ion bombardment and therefore uniform surface hardness and case depth.Plasma Nitriding is successfully carried out at a lower temperature and at a greater rate than gas nitriding. Plasma Nitriding at low temperature enables components to be treated without the loss of base hardness and without distortion, provided that the components are in a stress-free condition before they are nitrided.

We provide this service across Pan India with a turnaround time of 4 days, depending on the project requirements.

High Temperature Nitriding of Stainless Steel (Solution Nitriding): The steel used in the food sector, chemicals industry, medical technology and turbine construction sectors is often subjected to particularly high levels of wear and tear. This steel has to be both extra-hard and also highly resistant to corrosion. Stainless steels are applied in various industries to take advantage of their corrosion resistance. Unfortunately, the most corrosion resistant are not very durable in wear or load-carrying applications. Producing a nitrogen-enriched surface layer with increased hardness and higher residual stress increases the wear resistance and load-carrying capability in addition to improving the resistance to cavitation, erosion and corrosion attack. The strength of stainless steel can in theory be increased by alloying with nitrogen. However this cannot be done using conventional alloying techniques, as the low solubility of nitrogen in molten steel makes it difficult to add. We offer solution nitriding which is a unique solution to this problem. Nitrogenising at a depth of 0.1 to 3 mm can be used to surface-harden both austenitic and martensitic stainless steels. The dispersion of nitrogen atoms into steel leads both to a considerable increase in strength and an improvement in corrosion resistance. The quenching process is a key part of this procedure. Steel treated with nitrogen at temperatures of between 1,050 C and 1,150 C is cooled so quickly that the otherwise normal precipitation of corrosion-creating nitrides does not take place. The process technology of the solution nitriding process is comparatively simple. The process gas used is nitrogen instead of the standard nitriding gas ammonia. Nitrogen is usually a protective atmosphere and has no nitriding capability. But at temperatures above 1050 C (1920 F), the otherwise stable nitrogen molecule dissociates at metallic surfaces into atomic nitrogen. Despite the passive chromium-oxide layer at the surface of stainless steels, the dissociated atomic nitrogen is able to penetrate the surface and produce a nitrogen pickup. Two different process variants are available for this purpose: Solution nitriding M(SNM) & Solution Nitriding Austenitic (SNA) The SNM process is designed, for example, for use with stainless steel roller bearings and tools used in medical technology, along with the food industry and polymer processing sector, as well as being ideal for consumable parts used in the mineral-processing, chemicals and pump-construction sectors. This variant of the process creates a hard, martensitic top layer, while preserving a tough core section. The dissolved nitrogen provides greater resistance to corrosion, in both an acid and chloride environment.The SNA process is used for such flow related items as pumps, turbines and their corresponding valves and fittings, as it greatly increases resistance to cavitation erosion. In these cases, the process creates a hard, tough austenitic layer that offers great resistance to surface damage caused by corrosive, hostile environments. In these cases, the process creates a hard, tough austenitic layer that offers great resistance to surface damage caused by corrosive, hostile environments.

A more modern development of the nitriding process, also known as ion nitriding. In this process the component is made cathodic in relation to the furnace shell and nitrogen or ammonia gas is fed into the evacuated chamber. The glow discharge at the surface of the steel part produces atomic nitrogen by ionisation of the nitrogen or ammonia gas. Although this process uses more expensive equipment, it has the advantage of being extremely controllable. Also it has a time advantage compared with conventional gas nitriding and lower nitriding temperatures can be used (450/590 C). Nitriding commences as soon as the surface ionisation occurs, and since it is not necessary to wait until the whole cross section of the component reaches nitriding temperature, cycle times are shorter. Also the improved reaction conditions existing in vacuo provide cleaner treated components. A major benefit is the lack of white layer, due to the surface reactivity of the glow discharge. This same characteristic makes the process better suited to the nitriding of stainless steels and other high alloy steels, as their surface passive layers are broken down by the glow discharge, allowing uniform nitriding to be produced.

Gas Nitriding process Gas nitriding is a low temperature (typically 520 C/970 F), low distortion "thermochemical" heat treatment process carried out to enhance the surface properties of finished or near finished ferrous components. If a carbon spending gas is added, the process is called gas nitrocarburising. The layer usually consists of two zones the compound layer (white layer) which can be a cubic or hexagonal nitride and the diffusion layer below with dissolved nitrogen and hard nitride precipitations. The compound layer on the surface of the parts is responsible for the major benefit of high resistance to wear, scuffing, galling and seizure. The diffusion layer contributes improved fatigue strength and works as a support for the hard compound layer. By controlling and adjusting the process atmosphere, the constitution of the layer can be influenced from thin compound layers for fatigue strength improvement to thick nitrogen and carbon rich compound layers in case of gaseous nitrocarburising and post oxidation if good wear and corrosion resistance is desired. In this case Corr-I-Dur might be considered as the preferred choice.

Salt Bath Nitriding Process Services

Plasma Ion Nitriding is a process for surface treatment of metal parts to make them resistant to wear and fatigue.Parts to be treated are placed in a vacuum chamber and a high DC voltage (typically around 1000 volts) is established between the parts and the chamber wall. As nitrogen gas is introduced into the chamber, a glow discharge plasma (ionized gas) builds up around the parts. The reactive nitrogen atoms thus bombard the surface, forming a thin layer of hard metal nitrides. Advantages of Plasma Nitriding are:- Glow discharge that envelopes the entire surface achieves a consistent hardness and case depth. This is specially noticeable on complex geometries where gas nitriding case depths can be non-uniform. Plasma nitriding (H2+N2) least affects the surface finish of the product. Salt bath and gas nitriding, which uses ammonia (NH3) and phosphate for activa- tion , will roughen a ground or polished surface. Higher surface hardness is achieved at lower processing temperatures (500 C). Thus distortion is almost zero and no changes in the properties at the core of the material

It is recognized for offering high quality and environment friendly salt bath nitriding process services, which are preferred by a large number of clients throughout the country. All the services are available at market leading prices and within the expected time frame by customers. Salt bath nitriding is a thermo chemical process in which nitrogen and carbon are diffused simultaneously into the surface of the material. the high concentration of nitrogen chemically combines with iron and other nitride forming elements to produce an outer layer of epsilon iron nitride, which is thin, hard and ductile. This layer is also known as the compound zone, which has increased surface hardness to enhance anti-galling characteristics, and lowers the coefficient of friction. This compound zone also functions as a solid film lubricant by providing a non-metallic interface between mating surfaces. Nitrogen of lower concentration continues to diffuse below the compound zone and forms a solid solution with the base metal iron. This zone is referred to as the diffusion zone and is noted for its improvement in fatigue strength.

Nitriding is a case hardening process where nascent nitrogen is added to the surface of steel parts using disassociated anhydrous ammonia as the source. The process is controlled by monitoring how much of the ammonia has broken apart during the process.
