Plasma Nitriding Systems

Of all available nitriding processes, plasma nitriding provides the most consistent results and the highest level of reliability. Why? Because plasma nitriding systems use precisely controlled technology that ensures dependable quality.

Organizations looking for plasma nitriding systems have various options. At Electron, we offer IonHeat GlowTech, NitrEos, and GlowFit systems. Each system has its own unique properties. Read on to find out more about the various plasma nitriding solutions and their benefits.


Hardness and resistance

Stainless steel, particularly the austenitic stainless grades, is widely used in industry due to their corrosion resistance. The downside of these materials? They possess very poor mechanical properties – low surface hardness and wear resistance limit their usability. Plasma nitriding is one of the few effective ways to increase the surface hardness of stainless steel.

Plasma nitriding is an environmentally friendly and efficient nitriding process that uses plasma as energy source of gas nitriding species, cleaning power and energy to raise the temperature of the parts. It allows for a new level of precision and control, which results in uniform and consistent case hardening without the side effects (the release of polluting chemicals, high gas consumption) of other nitriding technologies.

Plasma ion nitriding technology

Ion/plasma nitriding processes are carried out in a vacuum vessel where a high-voltage electrical charge forms plasma. This process allows nitrogen ions to accelerate. As a result of this acceleration, the ions cling to the metal, heating it up, cleaning the surface, and allowing the metal to absorb nitrogen and carbon (in the case of plasma nitrocarburizing). This makes the surface of the metal more resilient to corrosion, erosion and galling.

At Electron, we don’t only have the products to help you use plasma nitriding technology in the best way, but we also specialize in co-engineering ion/plasma nitriding solutions with our customers. Thanks to years of experience in supplying the equipment and process knowledge, Electron can provide turnkey solutions or carry out a fast and efficient co-engineering process to get the best out of modern plasma ion nitriding technology.


Advantages of our plasma nitriding systems

Excellent plasma nitriding process control

The Hot-wall configuration of our furnace systems is equipped with independent heating and cooling zones for excellent temperature uniformity. Everything is controlled from a PLC without the further presence of an operator. This provides better process control and repeatability, allowing engineers to guard the security and efficiency of processes, focus on the technical aspects of the production process, design, implement, test and upgrade processes, reduce the energy consumption and lower your organization’s carbon footprint. CEO’s can count on profit maximization, continuity, minimum downtime, cost efficiency, innovative product technology, improved sustainability, and a small machine footprint.

Quality electronics

The electronics for the control (a DC current limiter, an ultra-fast spark detection system, and an adjustable frequency and duty cycle) meet the strictest quality requirements. The result? Better process control and repeatability, resulting in safer, more efficient, and more flexibility when it comes to fast production changeovers. Quality electronics also make it easier to take the development of production lines and system processes to the next level.

Tandem nitiriding system

If required, the system can be run in tandem. This means that you can use the same control, vacuum system, and gas input for two separate process chambers. This gives you the flexibility needed for increased productivity and lower initial investment.

Minimum floor space

Our system design takes up a modest amount of floor space. Depending on your preferences, a single rotating column lifts and rotates both vessels in an individual or tandem system. This leads to a more efficient use of floor space without compromising on safety.

Cleaner and more efficient plasma nitriding processes

Plasma nitriding is cleaner and more efficient than conventional nitriding techniques. It uses lower processing temperatures, produces almost zero contamination, and supports faster treatment cycles. This not only leads to lower costs and fewer environmental issues but also minimizes the need to replace costlier materials on a regular basis. Electron is specialized in developing and implementing the necessary tools for environmentally friendly and efficient nitriding processes that use plasma as an energy source.

Ion/plasma nitriding applications

Plasma nitriding has become a popular technology in the industrial community. Applications include gears, crankshafts, camshafts, cam followers, valve parts, extruder screws, pressure-die-casting tools, forging dies, cold forming tools, injectors and plastic-mold tools, long shafts, and axis, clutch and engine parts. Plasma nitriding technology is also used in the aerospace industry to improve the reliability and durability of commonly used materials such as Aluminum, stainless steel, Titanium and Nitralloys and Nickel alloys.

What ion/plasma nitriding technology ultimately does is case-hardening. It hardens the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal at the surface. The process makes hardened metal more resistant to surface wear. Ideal for objects that are subject to sliding contact with hard or abrasive materials.

IonHeat GlowFit units

You could describe the IonHeat GlowFit unit as a new heart to modernize your old furnace. The “old school” ion nitriding systems from the twentieth century still have the capacity to nitride your parts like champs! But why would you want to convert an existing furnace?

Efficiency gain and cost savings are two excellent reasons, especially in a time in which energy bills are going through the roof.

Installing our retrofitting kit will allow you to upgrade existing plants with new controls, gas panels, top-of-the-line plasma power supplies, and our unique SCADA man/machine software. GlowFit units can be used for existing cold-wall or hot-wall units.
