Ion nitriding achieves repetitive metallurgical results and complete control of the nitrided layers. Absolutely. Advantages and disadvantages of Nitriding process: Advantages and disadvantages of Nitriding process is explain as below. 11) Nitriding process is clean process because this process not produce carbon. ) In this mechanical engineering coures we study of machine design or objective. Advanced Heat Treat Corp. All Rights Reserved. Eco-friendliness. Iron fits like a puzzle piece to nitride, which is a form of nitrogen. We take great care to ensure the quality of your metal, such as preventing the hollow cathode effect. Compared to gas nitriding, this process takes much less time and resources. The only gas plasma requires is nitrogen, but it's often done with hydrogen, argon, and methane. While we do regulate the temperature in plasma nitriding, it's the electricity that causes the reaction. Advantage of Nitriding process . So, what is it that makes ion nitriding worth it? The process is non-toxic, using half as much energy and gas as other methods.It's as clean as brushing your teeth. 7) Nitriding process required less time. This method of hardening is extremely efficient and dynamic. ConversionConversion Blog written by Jake McCann, Metallurgist at our corporate office in Waterloo, Iowa. You don't have to worry about one side being coated and the other not. Why not use the most eco-friendly and consistent process out there? Usually, you need a particular temperature for nitrogen to be ready for this process. No polishing or post-treatment is necessary for surfaces, but it can be done if you need super smooth metal. EmoticonEmoticon. Both processes increase surface hardness based on nitrogen diffusion into the product, increasing usable life span, wear resistance and/or fatigue strength, depending on the alloy. dangerous.). Need help deciding which option you should choose? Originally posted July 2018. Hot strength up to 400°C. This website uses cookies to help us give you the best experience when you visit. Let’s take a look at the specific pros and cons of each: As you can see, there are definite advantages and disadvantages to both processes, which is why it’s critical to involve your heat treat specialist during the design phase. Please fill out the form below and an AHT Technical Expert will be in touch shortly. posted Let's get in touch and talk about what kind of nitriding is best for you. A computerized control system for gas nitriding has been developed in recent years, allowing complete monitoring of the thermodynamic properties involved, as well as oxygen levels. The result is a very hard but thinner layer, which is more resistant to shock loading conditions. As we've said, the size of the furnace determines the size of your metal. This control results in superior fatigue performance, wear resistance, and hard layer ductility. So it's only natural that steel alloys should react well to the gas. Contact us today to get started. Advantages and disadvantages of Nitriding process. 3) No heat treatment is used after Nitriding. Blog. © 2010 - 2019 Miheu d.o.o. No bending, rolling, or pressing will break it down easily. Its chief advantages … In this lecture we study of what is advantages and disadvantages of Nitriding process. Superior adhesive wear resistance thanks to the ceramic characteristics of the surface. Plasma ion nitriding is a distortion-free process. Learn about the pros and cons of both ion nitriding and gas nitriding to help you determine the best option for your heat treat needs. 6) Nitriding is improved the fatigue properties of materials. 2) High furnace cost required for Nitriding process. A case-hardening technique in use since the early 20 th century, nitriding steel has been an effective lower-temperature heat treatment for workpieces longer than engineers and metallurgists fully understood it.. Its appeal lies in the ability to harden a part by dissolving nitrogen into its surface without austenitizing, thus all but eliminating the risk of distortion. 5) resistance against Abrasive and adhesive wear is increased. Since then, we've refined and mastered what they called "glow discharge" to rise to the top of the Slovenian heat treatment game. Flexibility. But there are also very large differences, which could make a direct impact on your parts. While it can sustain huge temperatures and last you a long time, it depends on your metal and how you're using it. Tools and small components are often liquid-nitrided. Unlike gas nitriding, these chemicals aren't the method's main mechanism. Especially when you're dealing with iron-based materials or porous substances like sintered steel. Those processes are strong in different circumstances, but plasma nitriding is nontoxic, flexible, and precise. Privacy Statement | Site by Spinutech, Ion Nitriding vs Gas Nitriding: The Pros and Cons, Engineering and Torsion Fatigue Resistance, Iowa (Waterloo - Corporate Office & Service Center), Ion and Gas Ferritic Nitrocarburizing (FNC), "S" Phase Low Temperature Stainless Steel Nitriding, Very precise temperature control – this leads to consistent and predictable case depth / hardness / dimensional stability, Full coverage of nitriding - even inside holes and bores, Great for large quantities of small parts (batch style product), Great for alloy steels and low carbon steels, Without required knowledge, compound zone thickness can exceed desired limits, Product with too much compound zone could require grinding or machining to remove or reduce this layer, Parts must be sufficiently “clean” before processing, otherwise “dirty” parts can lead to delayed or inhibited nitriding areas, Copper plating or masking paint is required to prevent nitriding, Difficult to process stainless steels due to surface activation requirements, Increases surface roughness, but to a less degree as compared to ion nitriding, Mechanical masking (sometimes reusable) can be used to prevent nitriding of specific areas of the product, Great process for alloy steels and stainless steels that require surface activation to allow for nitriding, Ion bombardment helps “sputter” clean the surface, Gases used for processing are safe and environmentally friendly, Limited on compound zone thickness (maximum) due to the nature of the process, Relatively less superior temperature control (as compared to gas) – this can lead to variance in case depth / hardness / dimensional stability. This is because we do it at a mid-temperature which relieves the tension of steel while keeping it intact. Compared to gas nitriding, this process takes much less time and resources. Copyright © Much like a drunken one-night stand. The vacuum nitriding service can significantly improve the fatigue strength and service life of the parts, with the advantages of case depth up to 0.025 and improved wear and abrasion resistance due to 40-70% increase in surface hardness. | Production: TrueCAD d.o.o. Once said gases fill up the back, high-power electric fields bathe the product in a steady voltage, forming ionized molecules. It provides similar advantages as gas nitriding. What makes this process so important, and why do we do it? Hello friends my name is Roshan Namdeo Waje and founder of mechstudy.here I shere the imforfation about mechanical engineering. Advantages and Disadvantages of Ion Nitriding. This method is similar to nitriding except that nitrogen and carbon are introduced into the surface of the work piece.This is achieved by heating the part in a molten salt hath for 2—4 hours. 8) Nitriding materials have higher endurance limit under the bending stress. Consistency. In reality, the disadvantages of ion nitriding are much fewer than that of gas nitriding. Treatment advantages of vacuum nitriding service. Although your mileage may vary, plasma nitriding is superior to other forms of case hardening in its wear resistance, sensible process, and high control. In this article, we're going to discuss how plasma nitriding works and why it's necessary for modern steel quality. 6) Nitriding process is application only for alloy steel containing Nitriding elements. If you need to coat a variety of different metals, it'll take multiple batches, since the regulation temperature will be different for each kind. On Friday, May 29, 2020 We can deal with heavier metals this way, creating layers regularly and efficiently. What you should choose depends on your situation. These first layers can be about 20 microns thick, already doing wonders for your metal. This is plasma. MIHEU, Heat Treatment Solutions & CNC Custom Machining, Šentjanž pri Dravogradu 176, 2373 Šentjanž pri Dravogradu. Surface changes.While ensuring minimal changes in size or shape, we can increase the metal's resistance to friction and corrosion. (But we can do some partial nitriding with gas.). But also, the technology and equipment behind plasma nitriding has a much higher cost. The Cost-Effectiveness of Ion Nitriding. It's simple to mask your metal.This means you can only add layers to part of the surface, as much or as little as you need. Advantages and disadvantages of Nitriding process . Liquid nitriding is used where low case-depth is required and is then cheaper. What is your budget? Whether you're into automobiles, planes, mechanics, or industry, you know one thing: During WWII, physicists Dr. Wehnheldt and Swiss Dr. Bernhard Berghaus developed a method of hardening steel without distortion or danger. No need for further machining operations. We're the biggest name in heat treatment in Slovenia, and we'll continue to invest our experience in the lives of our customers. Plasma nitriding is usually done for gears, crankshafts, cylinders, plastic molds, auto parts, industrial tools, and other mechanical parts that need strength. Advantages of vacuum nitriding treatment. That means your surface won't change at all. The compounds that are formed in this process deposit active nitrogen onto the material, forming a solid layer with carbon. 9) hardness of materials achieved without using the oil ,air quench. In addition, in both gas and ion, the compound zone (or white layer) increases corrosion resistance, and often a post-oxidation process can be applied to further enhance corrosion resistance. While every surface treatment has its advantages and disadvantages, gas and ion (plasma) nitriding are often compared when engineers decide what is best for their application. Just keep in mind there's no such thing as masking in the gas process. And like all things, the nitrided layer does wear with repeated contact. The forming plasma is visible through the window of the chamber. But also, the technology and equipment behind plasma nitriding has a much higher cost. One other form of nitriding is gas nitriding, which releases ammonia into a chamber, diffusing nitrogen onto the surface to create a solid layer.
