White Papers & Case Studies

  • Corrosion Resistance Testing & UltraOx

    Rich Johnson

    Advanced Heat Treat Corp. uses cyclic polarization to test and compare the corrosion resistance performance of UltraOx, conventional gas nitriding and unprocessed materials. Learn about AHT's testing capabilities and its trademarked corrosion resistance solution here.  

  • Ten Tips for When to Use Gas Nitriding

    R. Alexander

    With the variety of surface treatments available today, it can get confusing trying to decide which one is best for your application. Gas nitriding is becoming more and more popular since it is environmentally-friendly, while also offering significant benefits.

  • Surface Treatment of Stamping Dies Infographic

    See how UltraGlow® Ion Nitriding outperforms other surface treatments when it comes to stamping dies, with this infographic!

  • Case Study: Steel Mill Turns to UltraOx┬« to Fight Corrosion

    Advanced Heat Treat Corp. was approached by one of the premiere steel makers in the southeastern United States. The steel producer was having issues with corrosion in the hot working section of their mill. The high corrosion rate was attributed to two factors; heat and process water. Heat has been well documented as increasing corrosion in humid and/or wet environments.

  • How to Streamline Your Process for Heat Treat Success

    Joel Robinson

    In every major industry companies are taking notice of the positive effects that streamlining can have on their internal processes, and economic returns. Through these continuous improvement efforts, companies see cost reductions in categories such as turnaround time, reduction of defects, and elimination of waste, to name just a few. While these concepts are just getting a foothold in industries such as retail and medical, they have an established history in manufacturing. The heat treat industry, and specifically the ion/gas nitriding subset, is not an exception.

  • Metallurgy Basics (for Non-Metallurgists): What's Happening to Metals During Heat Treatment

    Learn how common metals, such as steels, are heated to high temperatures and the significant changes that occur at the atomic level.

  • The Pros & Cons of Induction Hardening

    Scot Clay

    Discover the pros and cons of the selective heat treatment: induction hardening.

  • Ion Nitriding Masking Capability Provides Perfect Solution for Automotive Clutch Hub Housing

    Mikel Woods

    In this white paper learn about ion nitriding, also known as plasma nitriding, and the benefits it provides for parts. In particular, read about how ion nitriding improved the wear resistance for an automotive club hub housing piece.

  • Why Your Long Parts Should be Ion Nitrided in a Vertical Vessel

    Gary Sharp

    Various heat treat methods are available to enhance wear resistance and provide surface hardening on long parts such as screws, shafts and rolls. Learn what the best method is for heat treating long parts and the longest part Advanced Heat Treat Corp. has ion nitrided.

  • Nitriding Tips for New Users

    Chad Clark

    Learn about common nitriding questions for new users.

Technical Papers

  • Nitriding FAQs for Purchasing Professionals

    Vasko Popovski, PE

    From size capabilities to cost/quotes to logistics, Advanced Heat Treat Corp covers ion and nitriding FAQs.

  • Influence of Nitriding Mechanisms on Surface Roughness of Plasma and Gas Nitrided/Nitrocarburized Gray Cast Iron

    E. Rolinski, A. Konieczny, G. Sharp

    The differences in mechanisms of nitrogen transfer between plasma (ion) nitriding and gas nitriding have various practical consequences. For example, gas nitriding increases the surface roughness of gray cast iron. Proper identification of the advantages and disadvantages of these two methods could significantly improve their use.

  • When and Why Ion Nitriding/Nitrocarburizing Makes Good Sense

    E. Rolinski and G. Sharp

    Ion nitriding can be used in many applications, but some are so unique that they can be called “the best” applications, where the competitive treatments such as salt bath and gas nitriding cannot easily duplicate the unique results of ion nitriding.

  • Plasma Nitriding Large Stamping Dies

    E. Rolinski, G. Sharp, A. Konieczny

    Plasma nitriding offers a way to significantly improve the surface properties of tool steel stamping dies, and is not limited by their size to its application, as are some alternative surface treatments.

  • Plasma, Gas Nitriding and Nitrocarburizing for Engineering Components and Metal-Forming Tools

    E. Rolinski, T. Damirgi and G. Sharp

    Wear, corrosion and fatigue properties are strongly dependent on surface quality and its modifications.[1] Thermochemical methods such as gas and plasma nitriding allow for enhancement of these properties in most severely loaded (mechanically and/or chemically) applications without causing any changes in dimensions of the treated objects.
