ABOUT US

In 1998 Ionic Technologies, Inc. was established through a partnership with Aalberts Industries of Doorn, Netherlands. Ionic Technologies  supports numerous major manufacturing firms by providing the highest level of Ion Nitriding and Vacuum Heat Treatment services for all types of metals. Read More

Ion Nitride

AMS 2759/8 In the 1980’s the first commercial application of the Ion Nitriding process was introduced into the United States.  This technology utilized a combination of vacuum, voltage, temperature and gas flow controllers that precisely control the final Nitriding phase.  In recent years, Ion Nitriding equipment manufacturers have made significant modifications in equipment, electronics and software design.   Ionic Technologies uses Pulse Plasma Generators that utilize the most current technology available.   These advances in technology have allowed Ionic Technologies to increase the tool performance and the value of our customer’s finished products to above market standards.

Gas Nitride

AMS 2759/6 & AMS 2759/10 Gas Nitriding is a surface hardening process in which nitrogen is added to the surface of steel using dissociated ammonia as the medium.  The result is a very hard case harden surface. Recent developments utilizing computer control of the atmosphere have led to a process that can be accurately controlled.  The thickness and phase formation of the Nitriding layer can now be selected and precisely maintained.

FNC (Ferritic Nitrocarburization)

AMS 2759/12 Ferritic Nitrocarburizing is a case hardening process that is used to produce a hard, wear resistant surface. Despite the name, the process is a modified form of nitriding, not carburizing.  However, both processes introduce nitrogen and carbon in the ferritic state.   The case hardening process diffuses nitrogen and carbon into ferrous metals at sub-critical temperatures.  Because of the low process temperature, little size change or shape distortion occurs allowing this process to be successfully applied to a wider variety of finished parts.  The process is more commonly applied to law alloy steels, mild steels and cast irons, but can also be applied to any steel which is thermally stable at the treatment temperature.   Benefits include:  wear resistance, scuffing/seizure Resistance, improved fatigue, improved corrosion resistance, good surface finish, and minimal shape distortion.

Solution Nitriding

Solution Nitriding is a nitriding process done in a special vacuum furnace at high temperatures and over pressure.  It provides a nitrogen enriched structure to most stainless steels.  It is primarily used for Martensitic materials where case depth of up to .040 deep is required.  It can also be used on austenitic materials such as 300 series and PH materials.  Some materials may require aging or tempering after this process.  It provides a deeper case depth than conventional nitriding and a corrosion resistant structure.

S-Phase Nitriding

AMS 2759/8, AMS 2759/10 The S-Phase increases the hardness of the surface and case depths up to 25 microns depending on the alloy.  Typical materials are 300 series, PH series and Duplex stainless steels.  In an effort to meet the high demands for a low fatigue, wear resistant stainless steel, Ionic Technologies has developed a proprietary method called Ionic Diffusion SS.

Vacuum Heat Treat

Our vacuum heat-treat department operates differently than most commercial shops.  Everything we process is controlled using control thermocouples planted in real parts. We run dedicated cycles for our customers using our Turbo Quench 10 and 12 bar hardening furnaces.  This eliminates any compromise that would be made by the majority of commercial heat treat shops.  Additionally, components that require optimum performance are processed in our cryogenic (or vacuum tempering) department as part of the heat treat process. Correct utilization of vacuum hardening can dramatically reduce the amount of grind stock required after the heat treat process. This saves you, the manufacturer, on machining costs allowing you a competitive advantage.

Cryogenic Treatments

If the heat-treat process is done correctly, it is possible to obtain 95% martensitic transformation; but the typical result is 70% or less and many tools will be below 50%.  The cryogenic process completes the transformation to near 98%-99% depending on the material. Martensite is the fine-grained structure that transforms from austenite during the quench cycle.  It is this desirable fine grain that should be found in all heat-treated tool steels. Cryogenic Treatments are common in precipitation hardening steels where dimensional stability is required.   Correct utilization of vacuum hardening can dramatically reduce the amount of grind stock required after the heat treat process. This saves you, the manufacturer, on machining costs allowing you a competitive advantage.
