Can treat Stainless Steels, Titanium and Nickel alloys, Low temperature (410°C) treatments possible. Plasma carburising and plasma nitriding are thermochemical processes for increasing the surface hardness of low carbon steels. 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. The process is gaining a great deal of popularity in North America due to legislation on process effluents, European engineering specifications and a growing awareness of the process repeatability and metallurgical consistency due to computer control (Fig. Several unique characteristics of ion/plasma nitriding enable applying it to a variety of ferrous and nonferrous alloys [2]. 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 controlled depth of hard alloy-nitrides. Composition and characteristics. IBC Coating Technologies has an established service center for Ion Plasma Nitriding, TD Coatings, Boriding, Boronizing, DLC, PEO Completed on near finished components – i.e. The nitriding of CoCrMo alloy has been carried out in a wide range of nitriding voltages (from -500 V to -1100 V) at 400 °C for duration of … Ion nitriding can be conducted at temperatures lower than those used in conventional heat treat process thereby providing excellent … Gas nitriding. Ionitech provided a solution by recommending the correct grade of steel to use, and the details of the pre-nitriding … The ability of to avoid dimensional change and deliver a uniform case on complex geometries. Stainless steels are used in aerospace applications requiring maximum mechanical strength and durability. 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 … Plasma nitriding/nitrocarburising is a modern thermochemical treatment which is carried out in a mixture of nitrogen, hydrogen and an optional carbon spending gas. Ion nitridingis also known as glow-discharge nitriding or plasma nitriding (Fig. Compound layer free for the highest fatigue resistance, and also for parts which are to be subsequently coated. Ion nitriding [3] is also known as glow-discharge nitriding or plasma nitriding (Fig. Compared with conventional carburising, they offer excellent control and repeatability, low energy consumption and fast heat treatment times. After World War II the plasma nitriding process received widespread acceptance in Germany, Russia, China and Japan. Uses a nitrogen reaction to produce a hard layer, giving wear and fatigue … Previously their problem was poor quality of the internal gear ring on the back axel, which was noisy in operation and exceeded EU noise requirement level. White layer (usually up to 15 µm depth) Diffusion layer (up to 0.8 mm depth (material dependent)) High wear resistance; Fields of Application. 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. Nitriding high-alloy steels, including stainless steels, are carried out at a temperature between 350°C and 600°C. Ideally, steels for nitriding should be in the hardened and tempered condition, requiring nitriding to … Maximum surface hardness of M5O and Tl steels was achieved by plasma nitriding in 15% nitrogen/85% hydrogen and varied logarithmically with atmosphere nitrogen content. Stress relieving. Plasma nitriding equipment consists of a vacuum vessel (retort), a pumping system to control the furnace pressure, a plasma generator and a cooling system. Plasma Nitriding in general is a heat treating that is used to case harden surfaces using nitrogen. In plasma nitriding, the reactivity of the nitriding media is not due to the temperature but to the gas ionized state. The nitrogen then diffuses onto the surface of the steel creating a nitride layer. : Hauck Heat Treatment Ltd, 39-43 Bilton Way, Luton, Bedfordshire, LU1 1UU, UK.
