… Products produced from this process include … Pulsed Plasma Nitriding (Furnace supplied by Eltropuls) improves the resistance to wear and the anti-friction qualities by increasing the surface hardness along the valve stem, while retaining the inherent corrosion resistance of the material at the valve seat. Nitrocarburising, generally of shorter duration (30 minutes - … Improved fatigue properties: the process induces compressive stress, which will improve fatigue strength. The only gas plasma requires is nitrogen, but it's often done with hydrogen, argon, and methane. These processes are gas nitriding, salt bath nitriding, and plasma nitriding. The process can be likened to natural plasma such as is often seen in the Northern Lights in the earths Northern hemisphere. Plasma nitriding is an alternative to ALLNIT ® low-pressure nitriding that BMI offers with its range of B5_R vacuum furnaces. Recently, Belavtomaz – the major truck manufacturer in the former USSR – installed Monometer Ionitech plasma nitriding furnace equipment. Low cost Plasma Nitriding HPPN - High Pulsed Plasma NitridingHPPN nitriding is a very low cost effective way to improve fatigue resistance, resistance on hertz pressure and hot hardness. requiring very minor (or zero) lapping, polishing or grinding. Plasma nitriding is a kind of thermochemical treatment that aims to improve surface properties of materials leading to increase in hardness, wear, corrosion and fatigue resistance. The Plasma Nitriding process techniques can also be known also as Glow discharge nitriding, or Plasma nitriding Continuous DC nitriding, Pulsed Plasma nitriding. As with carburising, nitriding can be carried out in any of the four states of matter (solid, liquid, gas and plasma). Plasma Nitriding We offer the widest range of Plasma Nitriding and Plasma Nitrocarburising facilities available in the UK. 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. Benefits. The plasma nitriding process began in the 1920's as an alternative to conventional gas nitriding. Effective case depths of up to 0.020-inch are formed in order to provide increased wear, fatigue and corrosion resistance properties. The opportunity to eliminate copper plate masking through use of simple mechanical masks. Pulsed Plasma Nitriding allows high temperature metallurgical reactions to occur at low work surface temperatures, plasma is produced by applying high voltage through a low pressure gas (a mixture of hydrogen and nitrogen) causing it to ionise, using this high energy (but thermally low temperature), plasma will diffuse nitrogen into the surface of the valve. Both processes produce little distortion of components and hence minimise the need for post-treatment machining or grinding. Plasma nitriding is the technological peak of the nitriding procedure and provides considerable advantages as compared to the salt bath and gas nitriding. Plasma carburising and plasma nitriding are thermochemical processes for increasing the surface hardness of low carbon steels. After World War II the plasma nitriding process received widespread acceptance in Germany, Russia, China and Japan. The process was not introduced into the United States until after 1950 and has only been used as a production process for the past 20-25 years. Plasma nitriding, also known as ion nitriding, plasma ion nitriding or glow-discharge nitriding, is an industrial surface hardening treatment for metallic materials. First, the product is sealed in a low-pressure vacuum. The potential for reducing scrap through precisely repeatable cycles. It is necessary to understand that there are two power-system types: continuous DC power a… Plasma nitriding, also known as ion nitriding, plasma ion nitriding or glow-discharge nitriding, is an industrial surface hardening treatment for metallic materials. Plasma nitriding. Plasma nitriding uses plasma discharge physic to diffuse nitrogen into the surface of a ferrous alloy. Low cost Plasma Nitriding HPPN – High Pulsed Plasma Nitriding HPPN nitriding is a very low cost effective way to improve fatigue resistance, resistance on hertz pressure and hot hardness. In simple terms the result is a nitrogen rich layer at the surface of steel which can be, dependant on the material treated, up to 1100 Hv. Pulse plasma nitriding provides optimum surface morphology and composition control within a … Completed on near finished components – i.e. The white compound layer can be minimised down to appropriate levels for the customer requirements. The compound-zone thickness was also measured by use of the SEM. Cold-wall furnaces use exclusively the plasma energy absorbed by the parts for heating, whereas hot … This process is the most cost efficient treatment for molds and dies for forming, die casting, forging, aluminium extrusion, plastic molding, and various precision components. Strategically located just minutes from the motorway network in the West Midlands region of the UK, Longwear Surface Treatments is in an ideal position to support your nitriding needs. Plasma Nitriding or Ion Nitriding is a significant development of the original Nitriding process. Pulse plasma systemUseful dimensions: Ø 800 x 1300 mm Ø 1200 x 1900 mm Ø 1500 x 2100 mm Procedure: Plasma nitriding DEW-Härterei Technik offers plasma nitriding. Due … During plasma nitriding, nitrogen capable of diffusion is supplied from the plasma to the surface; in gas nitriding, this is from ammonia gas. Ion nitriding can be conducted at temperatures lower than those used in conventional heat treat process thereby providing excellent … Plasma nitriding, also known as ion nitriding, plasma ion nitriding or glow-discharge nitriding, is an industrial surface hardening treatment for metallic materials. The Eltropuls patented ignition pulse allows stable plasma, minimum heat input, maximum treatable surface, thermal uniformity and minimum energy costs. Plasma nitriding uses plasma discharge physic to diffuse nitrogen into the surface of a ferrous alloy. Composition and characteristics. No reduction in the core hardness of the base metal or alloy of the component. Nitriding, process for hardening the surface of steel objects by introducing nitrogen (N) into it, where it combines with iron and other alloying elements to form hard metallic nitrides.
