One Minute Mentor: Plasma Nitriding Equipment

Cold-walled (double-walled water-cooled) systems were the first generation of plasma nitriding furnaces. This technology is also a vacuum-based process but employs the principle of glow discharge to provide energy for heating and nitriding at one time. Therefore, the independent control of the temperature stability and the nitriding intensity is not possible because both processes are using the same energy source—the plasma. The hot-wall plasma nitriding furnaces, the next generation of cold-wall ion nitriding systems, are

Solar Manufacturing receives US patent for a control thermocouple for vacuum heat treating furnaces

Solar Manufacturing,Sellersville, PA, announced that it has received US Patent #11,815,403 for an innovative control thermocouple design for vacuum heat treating furnaces. This new thermocouple offers a significant advantage in controlling operating temperatures from ambient up to 1200°F (649°C), particularly in smaller diameter hot zones of 36 inches (91.44 cm) or less. In conventional control thermocouple designs, the outer ceramic protection tube acts as a heat sink under these conditions. This thermal conduction, or heat

Beymetal Alüminyum rethinks innovation to improve Aluminum extrusion

Nitrex, Quebec, announced a collaboration with Beymetal Alüminyum, a leading player in the aluminum extrusion industry based in Türkiye, to modernize their nitriding capabilities. In its commitment to excellence and pursuit of progress, Beymetal partnered with Nitrex to improve efficiency and scalability in their in-house nitriding operations. The installation of a Nitrex batch-type nitriding/nitrocarburizing furnace has unlocked new possibilities in process efficiency and production capacity for Beymetal. The NX-1015 furnace model, with a 2,000 kg

Lindberg/MPH ships box furnace with automated load table to the aerospace industry

Lindberg/MPH, Riverside, MI, announced the shipment of a rod overbend box furnace with an automated load transfer table to the aerospace industry. This furnace will heat-treat parts under an inert atmosphere. The heat-treating furnace has a maximum temperature rating of 2,000°F and a load capacity of 6,000 lbs. It features a workspace of 36” W x 96” D x 36” H and is designed for a nitrogen atmosphere. A nitrogen gas flow meter controls the

The aviation industry chooses Seco/Warwick vacuum furnaces

Seco/Warwick, Meadville, PA announced that their previous furnace with an aviation industry client will be retired and replaced by a new, economical, and versatile furnace for brazing jet engine parts. Seco/Warwick has been a recognized metal heat treatment equipment manufacturer for decades. In fact in many plants, units were manufactured in the 1980s and 1990s. The partners are gradually replacing these units with modern solutions, continuing to be loyal to the SECO/WARWICK brand. “The aviation

One Minute Mentor: Process Control in Nitriding Systems

Modern gas nitriding and nitrocarburizing furnaces are equipped with sensor systems and a process control unit that allow the measurement and automatic control of the nitriding potential (KN). The figure shows an example of how the process control can be carried out.  Defined amounts of ammonia, nitrogen, and—for nitrocarburizing processes—carbon dioxide, can be chosen for each step in the program and fed into the furnace via mass flow controllers. The gas composition in the retort
