When working with hydrogen and nitrogen, the gas ratio can vary from 1:1 to 10:1. Pulsed Plasma Nitriding allows high temperature metallurgical reactions to occur at low work surface temperatures, plasma is produced by applying … Thermo-chemical process to enrich the case of a component or work piece with nitrogen; Due to the high amount of nitrogen in the atmosphere a diffusion zone as well as a white-layer or precipitation zone are formed. Also, no separate heating is required as the plasma provides sufficient heating of the component's surface to reach the process temperature of typically 500°C. Nitriding, conducted in gas (490 - 560°C) or plasma (400 - 590°C) for treatment times ranging up to 90 hours, involves the diffusion of nitrogen into the surface to produce a … 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. Plasma nitriding of steels is a well-established commercial surface-hardening process which provides wear, ... Cambridgeshire, UK). A hard compound layer of nitrides is … 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. Mechanical masking is the best option for large batch components. Ion nitriding, or plasma nitriding, is currently one of the most technologically advanced methods for case hardening of steel components. Learn more about induction hardening. A very high degree of control of the case depth and compound layer is achieved by this form of Nitriding. Plasma nitriding/nitrocarburising is a modern thermochemical treatment which is carried out in a mixture of nitrogen, hydrogen and an optional carbon spending gas. Plasma nitriding is an alternative to ALLNIT ® low-pressure nitriding that BMI offers with its range of B5_R vacuum furnaces. Improved fatigue properties: the process induces compressive stress, which will improve fatigue strength. A vital process for ensuring that components are stress free before being put into service. Plasma nitriding is a similar process to plasma carburising, but with the use of a nitrogen-hydrogen gas mixture rather than a hydrocarbon to produce the glow discharge plasma. 2,979 plasma nitriding products are offered for sale by suppliers on Alibaba.com, of which industrial furnace accounts for 3%, ceramics accounts for 1%, and electrical ceramics accounts for 1%. Ion nitriding, or plasma nitriding, is currently one of the most technologically advanced methods for case hardening of steel components. Plasma Nitriding.
